Well, I have to admit I am not using parameters mode too much recently; usually it buys you nothing.

I haven't check how SqlExp with explicit params works, but using parameters with SQL is very important. If you aren't using parameters, then server has to parse your SQL all the time. And very often parsing (and creating an execution plan) is more expensive than executing itself.

In any case, maybe you can try inverse conversion - from SetParam to SqlExp....

Actually, I'm planing to move from SetParam to my own database code as soon as I will be able to integrate it into TheIDE build system, which is unfortunately very hard to use in workspace-like way.
