- buffer.
-
- o If you aren't buffering rows, DBFIRSTROW(), DBCURROW(), and
- DBLASTROW() always have the same value. If you have enabled
- buffering by setting the DBBUFFER option, DBFIRSTROW() returns
- the number of the first row in the row buffer.
- o Note that the first row returned from SQL Server (whose value
- is 1) is not necessarily the first row in the row buffer. The
- rows in the row buffer are dependent on manipulation by the
- application program. See the dbclrbuf() manual page for
- details.
-
- PARAMETERS:
- dbproc - A pointer to the DBPROCESS structure that provides the
- connection for a particular front-end/SQL Server process. It
- contains all the information that DB-Library uses to manage
- communications and data between the front end and SQL Server.
