You can't. If you do a select it will expect it to be a singleton select and
raise an exception. If there is more than one record it will raise and
exception too.
Use a cursor and call First and then check to see if it is EOF. If not then
just ignore the returned record.

Hello,
How can I use TIB_DSQL to determine whether the dataset is empty or not?
Thanks,
Ronan
