Обсуждение: Retrieve Number of rows to be DELETEd

I'm using ECPG and embedded SQL.  In the C interface, there is a
PQcmdTuples() command which returns the number of rows affected by an SQL
statement.  In embedded SQL, other than doing a SELECT count(*) first, is
there a way to get the number of rows that may be/were affected by a
delete or update?

Thanks,
