Problem with ADO

Hy

I have the following SQL statement in the Cpp Builder 5.0 and I use
a Oracle Database

SELECT COUNT(STICHPROBENNUMMER) AS SP_COUNT FROM VT_RS_STICHPROBEN
WHERE STICHPROBENNUMMER = :Param1

The statement is correct, but ADO modifies the statement, so the
datebase gets

SELECT COUNT(STICHPROBENNUMMER) AS SP_COUNT FROM
VT_RS_STICHPROBEN.ROWID WHERE STICHPROBENNUMMER = :Param1

But with the ROWID it doesn't work, can someone give me a hint how to
solve this problem?

Thanks a lot in advance
