-
- o This routine determines whether the current Transact-SQL com-
- mand or remote procedure call generated a return status number.
- Status numbers are returned by all stored procedures running on
- a SQL Server whose version is 4.0 or above. Since status
- numbers are a feature of stored procedures, only a remote pro-
- cedure call or an EXECUTE command can generate a status number.
- o The dbretstatus() routine actually gets the status number.
- Stored procedures that complete normally return a status number
- of 0. For a list of return status numbers, see the Commands
- Reference.
-
- o When executing a stored procedure, the server returns the
- status number immediately after returning all other results.
- Therefore, the application can call dbhasretstat() only after
- processing the stored procedure's results by calling
- dbresults(), as well as dbnextrow() if appropriate. (Note that
- a stored procedure can generate several sets of results-one for

- ______________________________________________________________________
- each SELECT it contains. Before the application can call
- dbhasretstat() or dbretstatus(), it must call dbresults() and
- dbnextrow() as many times as necessary to process all the
- results.)
-
- o The order in which the application processes the status number
- and any return parameter values is unimportant.
- o For an example of this routine, see Example 8 in the DB-Library
- Reference Supplement.
-
- 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.
