Syntax

INT dbnumorders ( PDBPROCESS dbproc );

Arguments

dbproc

Is the DBPROCESS structure that is the handle for a particular workstation/ Microsoft® SQL Server™ process. It contains all the information that DB-Library uses to manage communications and data between the workstation and SQL Server.

Returns

The number of ORDER BY columns. If there is no ORDER BY clause, dbnumorders returns 0. If there is an error, dbnumorders returns -1.
