where clause for DT 1.10

Hello.

I'm upgrading to DT 1.10, and I don't understand how I can make a Where clause for MySQL.

At the end of the serverside_processing file, do I change "simple" to "complex" ? Do I add "complex" to the function the the html file? I've tried this with no success.

Sorry to seem obtuse, but I could not figure this out.

Thanks
