*Update (2008-09-19 10:05) - Solution:*
**My Solution:** Social engineering, I dug real hard and found someone who knew the schema name.
**Technical Solution:** Searching the .dmp file **did** yield the schema name.
Once I knew the schema name, I searched the dump file and learned where to find it.

Whether or not you would get a performance gain by partitioning the data depends on the data and the queries you will run on it.

RAM is relatively cheap (not that this is an excuse for poor memory managmentment). Unused memory is essentially WASTED memory. If you're hitting limits and the IDE is the problem consider less multitasking, adjusting your memory reqs, or buy more. I wouldn't cripple Eclipse if that's your bread-and-butter IDE. |

You **might** be able to do it on the server side. Alternately you could attach an onload event to swap the image src out. I guess the question then becomes, why would you have to use Javascript in the first pace?

Switch statement is faster to execute than the if-else-if ladder. This is due to the compiler's ability to optimise the switch statement.

There are two main types of drawing context in CSS that can be assigned to elements. One, `display: block`, creates positionable boxes. The other, `display: inline` flows the content as a series of lines within a box.

While it *is* true that using errors is more expensive, most people believe that a majority of their GUIDs are going to be computer generated so a `TRY-CATCH` isn't too expensive since it only generates cost on the `CATCH`.
