How to measure SQL hits due to my application

I've had a quick look at it - and attended AQTime training academy 101 :smileytongue: I can see that it would allow me to look at performance on a global scale.  It's big on the application side, but I don't see much on the SQL side.  I can't see any indication that it would be able to do someting like error my test if SQL performs more than X queries between the button click and the page being ready after the click.  Any experience that would confirm or deny my limited exposure to help me decide if I should use AQTime or write some sort of custom server side profiling scripts (I've got an idea involving stored procedures, xml files,SQL built-in functions and a touch of roasted fennel to make that work...). I'd prefer the former, but would be prepared to do the latter.  I just need input before I go and do redo something TC/AQTime can already do
