Hi All
I think there is a alternative solution, you can test with next(): if t=
here is
any row in the resultSet returns true and moves the cursor at first row=
. If
there isn't any row returns false.

You could always do a "SELECT COUNT (*)" SQL query first, this will tell you
how many rows you will get back then run the 'real' query if the answer is >
0
