- processed by dbresults() returned any rows. The application
- can call it after dbresults() returns SUCCEED.
-
- o The application must not call DBROWS() after dbnextrow(). The
- macro may return the wrong result at that time.
- o The application can use DBROWS() to determine whether it needs
- to call dbnextrow() to process result rows. If DBROWS()
- returns FAIL, the application can skip the dbnextrow() calls.
-
- o The DBCMDROW() macro determines whether the current command is
- one that can return rows (i.e., a Transact-SQL SELECT statement
- or an EXECUTE on a stored procedure containing a SELECT).
-
- PARAMETERS:
- dbproc - A pointer to the DBPROCESS structure that provides the
- connection for a particular front-end/SQL Server process. It
