dbaltutype

Returns the user-defined data type for a compute column.

Syntax

DBINT dbaltutype (
PDBPROCESS dbproc,
INT computeid,
INT column );

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.

computeid

Is the ID that identifies the COMPUTE clause. A SELECT statement can have multiple COMPUTE clauses, which can have varying numbers of aggregate operators and aggregate targets. The computeid is returned by dbnextrow or dbgetrow.

column

Is the number of the column. The first column is number 1.

Returns

The user-defined data type of the specified compute column on success and -1 on error.

Remarks

This function is defined as type DBINT, because both the DB-Library data type DBINT and user-defined data types are 32 bits long. Call dbaltutype only after dbnextrow or dbgetrow returns a computeid.
