Please note that the mail you were replying to is over five years old.
It is unlikely that the original author still reads this list.

The SQL_ATTR_PARAM_STATUS_PTR array returns whether a statement resulted in
an error. But a WHERE clause that matches zero rows is not considered an
error by the SQL standard.
To find out how many rows were deleted, you _must_ call SQLRowCount.
For a SQL_PARC_BATCH driver, you have to get each row count separately by
calling SQLRowCount/SQLMoreResults in a loop, as documented here:
