Query stats will show the cached plans, but not trivial ones. For that you'll want to use profiler to capture when they're executed....Such as a select * from tablename

"sql_handle" is not a recognized table hints option. If it is intended as a parameter to a table-valued function, ensure that your database compatibility mode is set to 90.

works fine for me.  make sure your db compatabilty is set to 90 (its likely 80 right now)
