dbrowtype

Returns the type of the current row.

STATUS dbrowtype ( PDBPROCESS dbproc );

where

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

One of four values:

If the current row is a regular row, REG_ROW is returned.
If the current row is a compute row, the computeid of the row is returned. (For information about computeid, see "dbaltbind.")
If no rows have been read, NO_MORE_ROWS is returned.
If dbrowtype was unsuccessful, FAIL is returned.

Because dbnextrow returns the type (regular or compute) of the current row, you can usually determine the row type without using dbrowtype.
