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 or Microsoft® SQL Server™ 2000 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.
