ADO and empty Dates [SOLVED]
|
Hello,
With ADORDD and Harbour there is a problem with emtpy dates.
When issuing an append blank, putting a ctod('') fails.
Also, FW_DateToSQL( , "D" ) fails too.
As I workarround, I set to date(), but there are some cases I need an emty date().
This is the code:
[code=fw:1bhpr914]<div class="fw" id="{CB}" style="font-family: monospace;"><br /><br /> aStruct := ADOSTRUCT<span style="color: #000000;">(</span> oRs <span style="color: #000000;">)</span><br /><br /><br /> <span style="color: #00C800;">FOR</span> n := <span style="color: #000000;">1</span> <span style="color: #0000ff;">TO</span> LEN<span style="color: #000000;">(</span> aStruct <span style="color: #000000;">)</span><br /> <span style="color: #00C800;">IF</span> aStruct<span style="color: #000000;">[</span> n, <span style="color: #000000;">6</span> <span style="color: #000000;">]</span><br /><br /> AADD<span style="color: #000000;">(</span> aCols, aStruct<span style="color: #000000;">[</span> n, <span style="color: #000000;">1</span> <span style="color: #000000;">]</span> <span style="color: #000000;">)</span><br /> AADD<span style="color: #000000;">(</span> aVals, HB_DECODE<span style="color: #000000;">(</span> aStruct<span style="color: #000000;">[</span> n, <span style="color: #000000;">2</span> <span style="color: #000000;">]</span>, <span style="color: #ff0000;">'C'</span>, Space<span style="color: #000000;">(</span> aStruct<span style="color: #000000;">[</span> n, <span style="color: #000000;">3</span> <span style="color: #000000;">]</span> <span style="color: #000000;">)</span>, <span style="color: #ff0000;">'D'</span>, FW_DateToSQL<span style="color: #000000;">(</span> , <span style="color: #ff0000;">"D"</span> <span style="color: #000000;">)</span>, <span style="color: #ff0000;">'L'</span>, .f., ;<br /> <span style="color: #ff0000;">'M'</span>, <span style="color: #ff0000;">""</span>, <span style="color: #ff0000;">'m'</span>, <span style="color: #ff0000;">""</span>, <span style="color: #ff0000;">'+'</span>, <span style="color: #000000;">0</span>, ;<br /> <span style="color: #ff0000;">'N'</span>, <span style="color: #00C800;">If</span><span style="color: #000000;">(</span> aStruct<span style="color: #000000;">[</span> n, <span style="color: #000000;">3</span> <span style="color: #000000;">]</span> == <span style="color: #000000;">0</span>, <span style="color: #000000;">0</span>, Val<span style="color: #000000;">(</span> <span style="color: #ff0000;">"0."</span> + Replicate<span style="color: #000000;">(</span> <span style="color: #ff0000;">'0'</span>, aStruct<span style="color: #000000;">[</span> n, <span style="color: #000000;">3</span> <span style="color: #000000;">]</span> <span style="color: #000000;">)</span> <span style="color: #000000;">)</span> <span style="color: #000000;">)</span>, ;<br /> <span style="color: #ff0000;">'T'</span>, CTOT<span style="color: #000000;">(</span> <span style="color: #ff0000;">''</span> <span style="color: #000000;">)</span>, <span style="color: #ff0000;">''</span> <span style="color: #000000;">)</span> <span style="color: #000000;">)</span><br /><br /> <span style="color: #00C800;">ENDIF</span><br /> <span style="color: #00C800;">NEXT</span><br /><br /><br /> oRs:<span style="color: #000000;">AddNew</span><span style="color: #000000;">(</span> aCols, aVals <span style="color: #000000;">)</span><br /> oRs:<span style="color: #0000ff;">Update</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /><br /><br /> </div>[/code:1bhpr914]

ADO and empty Dates [SOLVED]

FW_DateToSQL() and FW_ValToSQL() are meant to be used while constructing SQL statements.
FW_DateToSQL( CTOD( "" ) ) returns "NULL"
Example usage:
if we want to update a datefield:
[code=fw:b076l919]<div class="fw" id="{CB}" style="font-family: monospace;"><br />cSql := <span style="color: #ff0000;">"UPDATE MYTABLE SET DOCDT = "</span> + FW_DateToSQL<span style="color: #000000;">(</span> dDate <span style="color: #000000;">)</span> + <span style="color: #ff0000;">" WHERE ID = 10"</span><br />oCn:<span style="color: #000000;">Execute</span><span style="color: #000000;">(</span> cSql <span style="color: #000000;">)</span><br /> </div>[/code:b076l919]
Even better
cSql := SQL UPDATE MYTABLE SET DOCDT = dDate WHERE ID - 0
For ado, you may use FW_AdoNull() for updating or inserting empty dates

Hello,
I have a client that use my program on a network. before it was a version with DBF-files. Now I upgrade his program to ADO with MySQL.
The program is working very nice, but...
The customer don't quit the program at the evening, but all the PC go to 'Sleep-mode'. In the morning he resume the program, but than he get directly an error that the program can't write/access the database.
With the DBF-files he didn't get an error, but now he have to restart the program.
I know it's better to quit the program, but is there a way to fix this problem without restaring the program?

If it were me and your customer does not want to shut down his computer, I would go to the control panel and the power settings and on "Close Lid" .. set the option to "Do Nothing"
That way, your customer and just shut the lid and walk away and the laptop will not go to sleep.

Hi,
I was thinking to do a open again if it fails
like[code=fw:2h5ev0f2]<div class="fw" id="{CB}" style="font-family: monospace;"><span style="color: #00C800;">TRY</span><br /> oSQL:<span style="color: #000000;">execute</span><span style="color: #000000;">(</span> vCommando<span style="color: #000000;">)</span><br />CATCH oErr<br /> <span style="color: #00C800;">TRY</span><br /> oSQL:<span style="color: #000000;">Open</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /> CATCH oError<br /> <span style="color: #0000ff;">MsgInfo</span><span style="color: #000000;">(</span><span style="color: #ff0000;">"Failed to Connect to the Database "</span><span style="color: #000000;">)</span><br /> quit<br /> END<br />END <span style="color: #00C800;">TRY</span><br /> </div>[/code:2h5ev0f2]
I'm wondering that is would be a good solution?

Hi,
I just found out that there is a ADO-state-propery, so I can check that the connection is still OK.
I will try to use that.

oCn:State --> 0 = not open and 1 = open
But when server disconnects you, your oCn:State shows 1 though in real there is no connection.
To resume a connection you need to do:
[code=fw:2kdflhla]<div class="fw" id="{CB}" style="font-family: monospace;"><br />oCn:<span style="color: #000000;">Close</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /><span style="color: #00C800;">TRY</span><br /> oCon:<span style="color: #000000;">Open</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span><br />CATCH<br /> <span style="color: #B900B9;">// handle failure and exit</span><br />END<br /><span style="color: #00C800;">if</span> oCn:<span style="color: #000000;">State</span> == <span style="color: #000000;">0</span><br /> <span style="color: #B900B9;">// not connected</span><br /><span style="color: #00C800;">else</span><br /> <span style="color: #B900B9;">// connected .. go ahead</span><br /><span style="color: #00C800;">endif</span><br /> </div>[/code:2kdflhla]
When connection dies (due to loss of connectivity or server closing the connection), only way we know it when we get a runtime error. Any openration, even a recordset movement causes runtime eror.
So try to have a global error block directing to your own error routine:
1. Check if it is Ado Error ( check oCn:Errors collection )
2. If Ado error is it related to connection
a. If not call standard error routne
b. If yes, Try Resume connection as above and then return RETRY operation

Thank you Rao,
Indeed, I just found out that oCn:State is still open, even when I disconnected the network.
I try to use your suggestion, and put it in my global error-handler.
The only problem I have ir the network-connections was lost, and back OK-again (after resuming the PC) is when writing to the database, because, for reading I allways use a recordset that I open while reading it. If the connections is back OK, than it works.
But for opdating, writing to the database, I use a connection that I open in the beginning of my program, and close while exiting the program.

We are not opening a new connection again. We are closing and reopening the same connection that you opened first. Still do you get error while writing?
Meanwhile please also see

I know than whe are using the same connection again, but I was refering to recordset that are allways are reopen while calling.
But anyhow, it's working now, like you suggested. By closing the connection, and reopening it, if there was an error.
Thanks,

Glad it is working. Can you post your Code here for the benefit of all of us? Can we standardise this and integrate with fwh adofuncs library?
|

For now I have put in my functions I have made for myself for updating, deleting and adding records with ADO, because I needed it very fast for that customer.
I will put it in my error-handler, so it will work allways when there is an ADO-error. It will than also write the error in the error-file.
Now the customer just get an error that the connections was lost, and that the program can't reconnect anymore...
I will post the code after I put it in my error handler.

Hi,
After debugging the program, I finaly found the error that my customer get.
It is : 'MySQL server has gone away'
Now I'm looking a for a way to reconnect. I found something like oSql:ping(), fut there is also a possibility to auto-reconnect according to the MySQL-site.
Has anyone already did something like this?

ADO append con Uniqueidentifier en MSSQL

Manualmente hago asi para agregar un registro con el campo ID del tipo uniqueidentifier: (B85E62C3-DC56-40C0-852A-49F759AC68FB)
[code:5i9csd9t]
INSERT INTO articoli
(ID, Sub_ID, codice, descrizione)
VALUES (NEWID(), 15, 'uno', 'due')
[/code:5i9csd9t]
Alguien sabe como hacerlo con ADO?
[code:5i9csd9t]
FOR i := 1 TO 5000
oRs:AddNew()
//oRs:fields("ID"):VALUE := "NEWID()"
oRs:fields("Sub_ID"):VALUE := i
oRs:fields("codice"):value := "COD" + ALLTRIM( STR( i ) )
oRs:Fields( "descrizione" ):Value := "Descrizione articolo " + ALLTRIM( STR( i ) )
oRs:Update()
NEXT
[/code:5i9csd9t]
Gracias

ADO append con Uniqueidentifier en MSSQL

Fernando,
no puedo usar adordd porque no compila con la version de xharbour que uso yo, que no puedo cambiar porque uso FWH 2.7 que actualizaré apenas me lo permitan. De todos modos, no se si está previsto, pero cuando el campo es del tipo uniqueidentifier hay que llamar a una funcion NewID() para crear el uniqueidentifier, que manualmente se hace "INSERT INTO articoli (ID, codice) VALUES (NewID(), 'codigo uno')"
Mi problema es que con ADO no podia hacerlo en automatico, de todos modos lo he resuelto en este modo:
[code:1bqlnruj]
TRY
oRs:AddNew()
CATCH oError
MsgStop(oError:Operation+CRLF+oError:Description,"Ado Connection")
RETURN NIL
END TRY
TRY
oRs2 := oConnection:Execute("select newid()")
CATCH oError
MsgStop(oError:Operation+CRLF+oError:Description,"Ado Connection")
RETURN NIL
END TRY
cNewID := oRs2:fields(0):value
oRs:fields("ID"):VALUE := cNewID
oRs:fields("Sub_ID"):VALUE := i
oRs:fields("codice"):value := "COD" + ALLTRIM( STR( i ) )
oRs:Fields( "descrizione" ):Value := "Descrizione articolo " + ALLTRIM( STR( i ) )
oRs:Fields( "nota1" ):Value := REPLICATE("-=-", 800 )
oRs:Fields( "nota2" ):Value := REPLICATE("-+-", 800 )
oRs:Fields( "messaggio" ):Value := REPLICATE(".-.", 800 )
TRY
oRs2:close()
CATCH
END TRY
[/code:1bqlnruj]
Seria bueno preveerlo que en ADORDD (si ya no lo hace) que cuando el campo sea de este tipo, lo genere automaticamente al hacer un append.
Saludos y gracias de tu tiempo.

Con ado puedes utilizar el metodo Execute del objeto connection.
[code:1vn1im4w]
oCnn:Execute("INSERT INTO articoli (ID, Sub_ID, codice, descrizione) VALUES (NEWID(), 15, 'uno', 'due') ")
[/code:1vn1im4w]

Biel,
justamente, como habia leido aqui que RF decía que conviene usar oRs:update() en vez del comando INSERT (o de repente yo lo entendí mal), es que quería saber como hacerlo con el recordset (:update() en vez que con :Execute()
gracias de tu tiempo.

[quote="Fernando Mancera":1ypgk66h]Hola Pedro,
En el mensaje referente a ADORDD un usuario posteo un link con todo lo necesario para hacer funcionar en xHarbour. Recuerda compilar el codigo fuente de ADORDD con tu version de xHarbour.
[url:1ypgk66h]http://rapidshare.com/files/29234022/adoRDD.rar.html[/url:1ypgk66h][/quote:1ypgk66h]
Fer,
compila tanto en xharbour como harbour.
por cierto, sería conveniente incluir las modificaciones en el cvs de harbour.
saludos

ADO back up full database

Hi,
Using ado/FW_ado functions as DBMS management irrespective of MYSQL, MSSQL, etc, is there a way to back up the whole database to a local file?
Thank you
|
ADO back up full database

Backup and Restore are specific to each database. There is no common support in ADO.
For MySql, we can use FWH oCon:Backup(...) and oCon:Restore(...) methods.

Thank you very much for replying. I am looking for an approach via ADO for MySQL/MSSQL/María DB, therefore neutral from the point of view of the database.
I think this method exists, but I haven't found its parameters.

com ODBC eu fiz assim:
[code:2frtg540]Function Teste(oMeter) // Ler arquivos Excel com ODBC
local oDbc := TOdbc():New() // criar o ODBC no Windows !
local n := 1
local oAdo := TdbOdbc():New("SELECT * FROM [folha1$]", oDbc)
oMeter:nTotal := oAdo:RecCount()
While !oAdo:eof()
++n
oMeter:cText := padr(oAdo:FieldGet(1),18) + " " + padr( oAdo:FieldGet(2) ,20)
oMeter:Set(n)
oMeter:refresh()
oAdo:skip()
End
return nil[/code:2frtg540]
* isto funcionou, mas eu tenho que criar a conexao na maquina do usuario para funcionar, gostaria de algo direto.

ADO con MySQL problema con recordset
|
Estoy comenzando a trabajar con ADO y MySql hasta aquí hice un pequeño mantenedor de una tabla de artículos en la que puedo agregar, eliminar y crear registros desde el recordset y funciona bien, pero luego despues de unos minutos de operar (modificabdo y creando) aparece el error mas abajo, lo he probado como localhost y conectandome a una DB remota. Será porque se desconecta del servidor?, porque despues al volver a entrar funciona por un tiempo y se cae nuevamente.

ADO con SQL comando nativos.

Amigos:
Que necesito y donde lo consigo..
para usar ADO con SQL Server y usar lo comandos nativos SQL.
Después de saber un poco mas de SQL probare el ADORDD.
Muchas gracias.

No necesitas nada, Windows trae instalado todo, el proveedor ADO para SQL Server.
Solo necesitarias un SQL Servers instalado y listo, ha claro y la cadena de conexion.
De ahi en fuera, tienes todo puesto para comenzar a utilizar ADO directamente desde tu programa FW.

ADO enhansed TwBrowse ?
|
To All
Working with a local access table and FWH Twbrowse seems to work with decent responce in painting the listbox .. BUT .. connecting to a SQL server using ADO and FW Twbrowse is very slow ..
The ( fwh ) Browse will start and you will see a corner in the left open and sit there till Twbrowse can get it's 'bearings'. I realize that Twbrowse has to figure out it's parameters. top, bottom, recno?? but it is painfully slow.
Even worse is Hernan's TwBrowse replacement class .. it never opens the recordset... and looking at the code .. it doesn't even take into consideration ADO .. just rdd and I am not using an rdd to calc the recordset.
Is there a way to modify either FW TWbrowse or Hernan's Twbrowse to give any better performance with ADO.
Thanks
Rick Lipkin

Have you already tested the free ADORDD that we have published ?

To be honest with you .. no, I have not tried the adordd. Would you be so kind as to send it to my private e-mail .. I will give it a good test..
I have been following your development .. does the download include a brief readme on the syntax .. for the connection strings ?? I guess the .ch would tell me a great deal as well ..
Be anxious to see how it works.

Rick:
Where are your placing the RecordSet Cursor ?
For browsing my best advice is to place the cursor on the client size because in the server size it takes ALOT of time on retrieving data.
Have you modified the gotop, gobottom, bskip and blogiclen blocks ?

Rick,
Check the source code of the ADORDD to see how we do it:
oAdo := TOleAuto():New( "ADODB.Recordset" )
oAdo:CursorType = adOpenDynamic
oAdo:CursorLocation = adUseClient
oAdo:LockType = adLockPessimistic
|
ADO enhansed TwBrowse ?

Antonio and Fernando
I am looking at the adordd.prg and I see how you are creating the recordset ..
oADO := TOleAuto():New( "ADODB.Recordset" )
oAdo:CursorType = adOpenDynamic
oAdo:CursorLocation = adUseClient
oAdo:LockType = adLockPessimistic
oAdo:Open( s_cQuery + s_cTableName, s_aConnections[ nWA ] )
//--- my code
oRs := CREATEOBJECT( "ADODB.Recordset" )
TRY
oRS:Open( "SELECT * FROM CERT_DATA order by Name", "Provider=SQLOLEDB;Data Source=WEBDB02;Initial Catalog=DRUG_CONTROL;User Id=drugcontroluser;Password=r2x6j3q4", 1,3 )
CATCH oErr
MsgInfo( "Error in Opening CERT_DATA table" )
RETURN NIL
END TRY
Please excuse the dumb question .. what is the difference in :
oADO := TOleAuto():New( "ADODB.Recordset" )
and
oRs := CREATEOBJECT( "ADODB.Recordset" )
I take it that this is what you were driving at with a client cursor vs a server cursor ??
If that is correct .. does the last two parameters 1,3 .. still allow the client recordset update visability back and forth from other network clients ??
Being rdd .. how do I define field vars and how do I write them back .. can I do something like :
Select 1
USE (AllTrim(cDbf)) VIA "ADORDD" TABLE AllTrim(cTable) SQL ;
FROM AllTrim(cFrom) USER AllTrim(cUser) PASSWORD AllTrim(cPsw)
then reference my vars with cWhatever := a->whatever and then write them back like a->whatever := cWhatever ?
I take it record locks are still not relevant here since the database handles the oportunistic locking ?? 1,3 )
I am looking forward to seeing how this works .. I will let you all know sometime tomorrow ..
Many thanks
Rick Lipkin

Rick:
I reviewed your code all seems to look all rigth, I mean, the movement blocks are correct but, you have to "prepare" your RecordSet BEFORE open the query.
To "prepare" the cursor, you have to follow Antonio's instructions and use the ::CursorType, ::CursorLocation, and ::locktype properties before opening the recordset, if you don't prepare the recordset, the cursortype is Forward Only, the cursor location is on server size and the Locktype is Optimistic (default values), I guess that's why the browsing is slow.

I got a working browse with my code and YES .. the listbox is MUCH better when the recordset is cached locally.
Still takes a while to 'fetch' the recordset .. but that is based on the connection to the server .. which is ( in my case here ) a considerable distance from my location.
I have not tried multiple workstations updating records and the visability of those changes .. any thoughts there ??
What about indexes .. or TAGS .. generally speaking I was creating the ORDER by in the SQL statement as to how I want to see the records and on the relational tables .. opening a recordset with the sql clause .. WHERE ASSOCIATED_FILE_NUM ='"+cFILENUM+"'"+" order by date_" .. not even using an index.
In traditional dbfcdx rdd .. there is a set scope .. or filter .. I see in the adordd code:
STATIC FUNCTION ADO_SETFILTER( nWA, aFilterInfo )
local oADO := USRRDD_AREADATA( nWA )[ 1 ]
oADO:Filter = SQLTranslate( aFilterInfo[ UR_FRI_CEXPR ] )
RETURN SUCCESS
STATIC FUNCTION ADO_CLEARFILTER( nWA )
local oADO := USRRDD_AREADATA( nWA )[ 1 ]
TRY
oADO:Filter = ""
#ifndef __XHARBOUR__
CATCH
FINALLY
#else
CATCH oError
Alert( oError:Operation )
END
#endif
RETURN SUCCESS
How is that translated into rdd ?? ... set index to... set order to tag ... LOCATE ??
#command LOCATE [FOR <for>] [WHILE <while>] [NEXT <next>] ;
[RECORD <rec>] [<rest:REST>] [ALL] => ;
[ HB_AdoSetLocateFor( <(for)> ); ] ;
__dbLocate( <{for}>, <{while}>, <next>, <rec>, <.rest.> )
I know this is still a work in progress .. MARVELOUS WORK so far !!

ADO enhansed TwBrowse ?
|
Rick,
>
I got a working browse with my code and YES .. the listbox is MUCH better when the recordset is cached locally.
Still takes a while to 'fetch' the recordset .. but that is based on the connection to the server .. which is ( in my case here ) a considerable distance from my location.
>
You may try setting the recordset CacheSize value. We have not implemented it yet, but we plan to do it:
oAdo:CacheSize := 50
>
I have not tried multiple workstations updating records and the visability of those changes .. any thoughts there ??
>
ADORDD uses oAdo:CursorType = adOpenDynamic so the changes should become visible from all workstations
> What about indexes .. or TAGS
We have not implemented them yet. Probably we will do it along this next weekend
You can use SET FILTER TO <expression> and SET FILTER TO, to clear the filter. Same as Clipper. For SQL expressions, write them between quotation marks
We are glad that you are enjoying the ADORDD <!-- s:-) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":-)" title="Smile" /><!-- s:-) -->

ADO enhansed TwBrowse ?

Antonio
oAdo:CacheSize had no effect at any value .... but I am not complaining. This is a table with about 25k records .. and I have tested it at this location ( on the 'outer rim' ) and close to the core router. The closer to the core router .. the faster the 'fetch'
Just thought I would let you know about the cachesize

P.D. No puedo hacer las pruebas con la nueva clase porque me da errores varios, porque seguramente con la version de xharbour que tengo no van de acuerdo y por ahora no puedo actualizar FW.

ADO error en la conexion...

Parece cosa de locos... hace 5 dias que estoy con este problema, cuando decido poner el mensaje en el foro despues de 5 minutos descubro que el string de conexion que uso no era el adecuado.... Gracias a un mensaje de RF que dejó un link con todas las conexiones a sql <!-- m --><a class="postlink" href="http://www.connectionstrings.com/">http://www.connectionstrings.com/</a><!-- m --> y ahi encontré la que necesito...
"Provider=SQLNCLI;Server=PCPEDRO\SQLEXPRESS;Database=data_di_prova;Uid=sa;Pwd=1234"

ADO events
|
Hi !
It's needful to adopt one event in ADO objects . I found an VFP sample ,
it demonstrate what I want to do :
#DEFINE C_VFPCOMCLASS 'vfpcom.comutil'
oVFPCOM = CreateObject(C_VFPCOMCLASS)
oRecordSet = CreateObject('ADODB.RECORDSET')
oRecordSet.CursorType = 3 && adOpenStatic
oRecordSet.LockType = 1 && adLockReadOnly
oRecordSet.Open('SELECT * FROM AUTHORS', + ;
'Provider=sqloledb;Server=MYSQL1;' + ;
'Initial Catalog= pubs;UId=sa;PWD=; ')
oEvents = CreateObject('adoevents')
nError = oVFPCOM.BindEvents(oRecordSet, oEvents)
oRecordSet.MoveNext
DEFINE CLASS adoevents AS Session
PROCEDURE WillMove(adReason, adStatus, pRecordset)
WAIT WINDOW 'Moving one record...' NOWAIT
ENDPROC
ENDDEFINE
The problem is that this example is adapted to VFP COM object . So my
question it will second : can I manage events of recordsets without COM
object ( as in sample ) ? Only with ADO objects ?
If yes , can you show some source how to do that ? It's needful to
recognize movings events on recordset and then to do some things .
Many thanks in adcvance ! With best regards ! Rimantas

ADO for ADS?
|
Mr. Rao;
I now see how you have been working on making standardized ADO functions that work across a number of different sql engines. I have been using ADS for many years quite successfully. I mostly work via ACE32 and the ADS RDDs. I would assume that it is just as possible to work with ADS using ADO. If so, why not make the FW ADO functions compatible with ADS? Can I help? I already have a TAdsQuery() class to execute sqls and even allows you to treat a returning cursor as an array or as TData object.
as in:
[code=fw:15u45rea]<div class="fw" id="{CB}" style="font-family: monospace;"><span style="color: #B900B9;">//------------------------------------------------------------------------------</span><br /><span style="color: #00C800;">METHOD</span> SaveIdImage<span style="color: #000000;">(</span><span style="color: #000000;">)</span> <span style="color: #00C800;">CLASS</span> Tpatient<br /> <span style="color: #00C800;">LOCAL</span> binImage, oQ<br /><br /> <span style="color: #00C800;">IF</span> ::<span style="color: #000000;">cIDImageFile</span> != <span style="color: #00C800;">NIL</span> .AND. !EMPTY<span style="color: #000000;">(</span> ::<span style="color: #000000;">cIDImageFile</span> <span style="color: #000000;">)</span> .AND. file<span style="color: #000000;">(</span> ::<span style="color: #000000;">cIDImageFile</span> <span style="color: #000000;">)</span><br /><br /> binImage := MEMOREAD<span style="color: #000000;">(</span> ::<span style="color: #000000;">cIDImageFile</span> <span style="color: #000000;">)</span><br /><br /> oQ := TAdsQuery<span style="color: #000000;">(</span><span style="color: #000000;">)</span>:<span style="color: #00C800;">New</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /> oQ:<span style="color: #000000;">cSql</span> := <span style="color: #ff0000;">"UPDATE patients SET [image] = :bin_data WHERE recno = '$1$'"</span><br /> oQ:<span style="color: #000000;">aSubstitutes</span> := <span style="color: #000000;">{</span> ::<span style="color: #000000;">oPatTbl</span>:<span style="color: #000000;">VarRecNo</span> <span style="color: #000000;">}</span> <span style="color: #B900B9;">//StrTrans '$1$' for array contents on [1]</span><br /> oQ:<span style="color: #000000;">AdsPrepareSQL</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span> <span style="color: #B900B9;">//to prepare a paraetized query</span><br /> oQ:<span style="color: #000000;">SetParameters</span><span style="color: #000000;">(</span> <span style="color: #ff0000;">"bin_data"</span>, binImage, <span style="color: #ff0000;">"B"</span> <span style="color: #000000;">)</span> <span style="color: #B900B9;">//Parameterized query</span><br /> oQ:<span style="color: #000000;">RunAdsPreparedSql</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /> oQ:<span style="color: #000000;">End</span><span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /><br /> <span style="color: #00C800;">ENDIF</span><br /><br /> <span style="color: #B900B9;">//fErase( ::cIDImageFile )</span><br /> <span style="color: #B900B9;">//ClearTmpfiles()</span><br /><br /><span style="color: #00C800;">RETURN</span> <span style="color: #00C800;">NIL</span><br /> </div>[/code:15u45rea]

ADO for ADS?
|
Honestly I still love ADS and miss ADS. But for the sheer size of our data, I would not have left ADS and migrated to Oracle.
You are aware that there are OLEDB providers for ADS and we can work with ADO.
But knowing both, my advice for you is to continue what you are doing. Do not go the ADO way using ADS' OleDb providers.
Please never think again. Please stick to what you are doing. ADS, using ace.lib is still the best way and what you are doing is still the best.
Now about how do we deal with the results of ADS SqlQuery. If you are using TData or TDataBase that is good.

ADO function to append table not DBF into a recordset

Hello,
Is there an FW ADO function to import or append an existing table accessed via ADO, not a DBF file, into a recordset?
Thank you.

ADO no me funciona en una tabla en especifico
|
Hola a todos,
... no tienen idea de lo que he buscado informacion sobre esto en la red, y finalmente he caido aqui, pues he llegado a la conclusion de que solamente Ustedes podran darme luz en esto.
Se trata del ampliamente expuesto en la red, problema del mensaje de error que aparece:
"No se puede encontrar la fila para su actualizacion: algunos valores han cambiado desde la ultima vez que se leyo"
A partir de alli, parece que la conexion con el recorset desaparece, pues todas las instrucciones que siguen aparecen con error, y nunca se ejecuta.
TOdo esto aparece al ejecutar una instruccion ::oRs:Update().
No me ocurre con todas las tablas de la base de datos, sino con una sola de ellas (hasta ahora no he comprobado con todas las tablas). A TODAS las tablas de la base de datos se le ha agregado un columna, al inicio, llamada "noreg", entero, auto_increment que lo utilizo como llave primaria.
Estoy usando xHarbour 0.99.3, FWH24, Borland 5.5.1, MySQL 3.23 (en modo local) e instale MyODBC 2.50
Hasta ahora he tratado lo siguiente:
1.- realizo las sustituciones con ::oRs:Fields(n):value := 'valor a cambiar', cambie a ::oRs:Fields('nombre del campo'):value := ´valor a cambiar', y el error persiste.
2.- realizo el ::oRs:Update() al final de las sustituciones. Cambie a realizar las sustituciones por ::oRs:Update('nombre del campo', 'valor a cambiar'), y el error persiste.
3.- Utilizo OPTION=3, y la cambie a OPTION=16387, y el error persiste.
4.- marque las dos primeras opciones en la configuracion de MyODBC en el COntrol Panel, y el error persiste.
5.- Ejecute todo con la opcion de Trazas seleccionada en Control Panel, y el archivo no me dice de nikngun error (o no se interpretarlo), y tambien seleccione la opcion de trazas con OPTION=7, y lo mismo.
6.- He leido todas las news de FW, y veo que nadie reporta esto.
7.- He buscado en la red, y aunque mucha gente lo reporta, nadie llega a una solucion. Algunos suguieren soluciones para VB, tales como utilizar los campos numericos en formato DOUBLE y no FLOAT, agregar un campo timestamp "dummy" a las tablas. Esto no lo he tratado aun.
Mi string de conexion es:
DRIVER={MySQL}; SERVER=localhost; DATABASE=XXXXXXX; UID=jllinas; PWD=XXXXXXXX; OPTION=16387
AL momento de conectar, el CursorLocation es adUseClient.
Para crear el recordset hago:
::oRs := CreateObject("ADODB.Recordset")
::oRs:Open( cQuery, uConn, nCursorType, nLockType, nOptions )
donde nCursorType es adOpenKeySet, nLockType es adLockOptimistic y nOptions es adCmdUnknown
He comprobado, y realmente el registro no se ha movido, comprobado entre la lectura y la escritura.
... no se que mas comprobar, a ver que estoy haciendo mal...
Me estoy tirando de los pelos que ya no me quedan!
AYUDA.... POR FAVOR !!!!!

ADO no me funciona en una tabla en especifico

Fernando,
Gracias adelantadas por contestar...
En efecto, comparando la forma que lo hago con lo que me expresas aqui, tenía solo diferencia en el ::oRs:CursorType, que al tu colocarle un valor de 3, significa que has seleccionado adOpenStatic. Ya habia observado que algunos otros compañeros asi lo hacian.
Lo cambié y el problema persiste. Lo probe de nuevo con la tabla en interes, y no funciona (reporta el mismo error), mientras que en otras tablas el problema no ocurre, y el ABM ocurre normalmente.
Una cosa que no entendi: incluyes aqui el parámetro ::oRs:MaxRecords := 0. ¿Que significa esto? no lo habia visto por ninguna otra parte...
Por otro lado, y ahora para todos:
¿En ADO existen nombres reservados, que no puedan utilizarse para nombres de columnas? Se que en MySQL existen, y ya pase por esta, pero no he verificado en ADO.... ¿Alguien sabe de esto?
Gracias a todos,

ADO no me funciona en una tabla en especifico

Julio , segun lo que indica la documentacion es esto.
Nos permite fijar el número máximo de registros que aceptará el objeto Recordset. El valor por defecto es 0 e indica que no existirá límite.
si quieres puedes anviarme la tabla o la bd, para ver si tambien a mi presenta los mismo problemas.

ADO no me funciona en una tabla en especifico

Gracias Fernando,
Dos cosas nuevas en esto:
- Primero, no se como pasarte la tabla en la cual tengo problemas. Yo utilizo MySQL, y todo depende de con cual motor de BD vas a buscar reproducir el mismo error que me pasa. Puedo enviarte la tabla en DBF a partir de la cual he creado la de MySQL (solo tiene 10 registros para probar), pero tú me diras.
- "Conversando" con José Luis Capel por MSN, me ha sugerido que integre las pruebas con el metodo Supports(), a ver si es que los metodos ::oRs:Update() y la propiedad ::oRs:BookMark estan soportadas por el proveedor (MySQL). El caso es que SI estan soportadas ambas. Anexo mas abajo el metodo Save(), que es con el cual me ocurre el problema. Se trata del mismo método Save() propuesto por JLC y que fuera publicado en su Blog..... pero muy, muy modificado, pues trato los valores en un buffer, y luego simplemente los grabo con el Update().
-----------------------------------------
METHOD Save() CLASS tAdoRs
LOCAL oError
LOCAL lResult
LOCAL n, nFields
LOCAL lChange := .F.
LOCAL uBkMrk
LOCAL cType
lResult := .T.
TRY
if ::lNeedUpd
if ::lBuffer
for n := 1 to len( ::aBuffer )
if ::oRs:Fields(n-1):value <> ::aBuffer[n]
cType := ::FieldType( n )
cName := ::FieldName( n )
do case
case cType = "D"
::oRs:Fields( cName ):value := if(::aBuffer[n]=CTOD(""), NIL, DTOC( ::aBuffer[n] ) )
otherwise
::oRs:Fields( cName ):value := ::aBuffer[n]
endcase
lChange := .T.
endif
next
endif
if lChange
MsgInfo( "Soporta el metodo UPDATE(): "+IIF(::oRs:Supports( adUpdate ),"Si","No" ) )
MsgInfo( "Soporta la propiedad BOOKMARK: "+IIF(::oRs:Supports( adBookMark ),"Si","No" ) )
IF ::oRs:Status() == adRecModified
::oRs:Update()
uBkMrk := ::Recno()
::oRs:Requery()
::Goto( uBkMrk )
ENDIF
endif
::lNeedUpd := .F.
endif
CATCH oError
lResult := .F.
MsgStop(oError:Operation+CRLF+;
oError:Description+CRLF+;
"Tabla: "+::cAlias+CRLF+;
"Columna: "+STR(n),"Ado Recordset - Método Save()")
END
RETURN lResult
Gracias anticipadas por cualquier sugerencia...

ADO no me funciona en una tabla en especifico
|
Bueno, a ver si "mato" dos de un tiro:
Primero, dejame comenzar con el último, Fernando:
- Para ver las clases originales sugeridas por jcapel, puedes visitar su blog que esta en [url:1207ic2h]http://www.capelblog.com[/url:1207ic2h]
- La tabla que me pides puedes descargarla en este enlace [url:1207ic2h]http://www.ssp.com.do/clientes.dbf[/url:1207ic2h]
Ahora para lo que me pide José Luis:
Debo comenzar por colocar a la disposición de todos las clases originales, propuestas por ti, modificadas por mi. Buscaré crear en mi blog un articulo donde comentaré los cambios que le he realizado. Por ahora, la puedes descargar de aqui [url:1207ic2h]http://www.ssp.com.do/adoclass.zip[/url:1207ic2h], el cual contiene las clases ADOCONN, ADORS y el archivo ADO.CH modificado.
[quote:1207ic2h]a. ¿Como creas el recordset? muestrame el código[/quote:1207ic2h]
Primero la conexion. Esto lo hago al momento de empezar con nuestro sistema, para conectar con ADO:
[code:1207ic2h]
oConexionAdo := tAdoConn():New()
lConectado := oConexionAdo:Open( MIP )
CursorWait()
oTables := oConexionAdo:OpenSchema( adSchemaTables )
aFiles := {}
DO WHILE !oTables:EOF()
AADD( aFiles, oTables:Fields(2):value )
oTables:MoveNext()
ENDDO
oTables:Close()
CursorArrow()
if len(aFiles) == 0
MsgAlert("No existen tablas sobre esta Base de datos, retornando...", "Busqueda de Tablas con ADO")
oConexionAdo:Close()
QUIT
endif
[/code:1207ic2h]
oCOnexionAdo es una variable (objeto) pública, MIP es la cadena de conexion, que para mi caso es:
[code:1207ic2h]
MIP := "DRIVER={MySQL}; SERVER=localhost; DATABASE=richardcar; UID=jllinas; PWD=XXXXXXXX; OPTION=16387"
[/code:1207ic2h]
Luego, para crear el recordset, utilizo este código:
[code:1207ic2h]
oDbf := tAdoRs():New()
oDbf:oRs:CursorLocation := adUseClient
oDbf:oRs:CursorType := adOpenForwardOnly
oDbf:oRs:LockType := adLockOptimistic
lReturn := oDbf:Open( cQuery, oConexionAdo:oConnection, adOpenKeyset, adLockOptimistic, adCmdUnknown, cAlias,, cOrder )
[/code:1207ic2h]
[quote:1207ic2h]b. ¿Como haces para modificar un registro? Muéstrame el código[/quote:1207ic2h]
Como puedes ver, para modificar un registro, siempre lo cargo a una variable tipo DATA de la clase ADORS que se llama ::buffer, y que es un arreglo simple y sencillo del registro donde está el puntero en el recordset. Este arreglo se accesa haciendo mencion a
"nombre del recordset":"nombre de la columna"
Por ejemplo, para la tabla que me da problemas, llamo "oClientes" al recorset, y para cambiar el valor en la columna llamada "nombre", simplemente hago
[code:1207ic2h]oClientes:Nombre := "JUAN PEREZ"[/code:1207ic2h]
Pero todo esto se hace en el buffer. Si vez el método ON ERROR al final de la clase ADORS, podrás ver que allí se realiza este milagro (no es un truco de mi autoría... lo segui simplemente después de ver a muchos hacerlo así).
Luego de esto, solo me queda grabar el registro...
Para "cargar" el registro desde el recordset tengo la siguiente función:
[code:1207ic2h]
FUNCTION DBGET( oDbf, lAgrega )
LOCAL nRecno := 1
IF lAgrega
oDbf:Blank()
ELSE
oDbf:Load()
ENDIF
RETURN NIL
[/code:1207ic2h]
donde oDbf es la variable objeto del recorset (para mi ejemplo, oClientes).
[quote:1207ic2h]c. ¿Como haces para grabar el registro? Muéstrame el código.[/quote:1207ic2h]
Luego, para grabarlo, tengo otra función, parecida a la anterior, pero que "coloca" el registro en el recordset:
[code:1207ic2h]
FUNCTION DBPUT( oDbf, lAgrega )
IF lAgrega
oDbf:Append()
oDbf:Save()
ELSE
oDbf:Save()
ENDIF
RETURN NIL
[/code:1207ic2h]
Creo que esto es todo. La tabla que me dá problemas la puedes descargar (en formato DBF) desde un enlace que incluí al principio de este mensaje.
Ojala y puedas ver algo que no este yo viendo ahora !!!
Gracias anticipadas,

Julio no se que problema haya, luego de hacer varias pruebas , el cambio el siguiente, oRs:Fields("Nombre"):= alltrim(cNombre) , no se harbour o xharbour agrege algun caracter al terminar de capturar o lo espacion en blanco no sean aceptados por ado.
de echo tambien tengo el mismo problema con una tabla, que ya estaba funcionando bien.
