dbordercol
Returns the ID of a column appearing in the most recently executed query's ORDER BY clause.
Syntax
INT dbordercol (
PDBPROCESS dbproc,
INT order );
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.
order
Is the ID that identifies the particular ORDER BY column. The first column named within the ORDER BY clause is number 1.
Returns
The column ID (based on the column's position in the select list) for the column in the specified place in the ORDER BY clause. If the order is invalid, then -1 is returned.
Remarks
Call dbordercol after dbresults has returned SUCCEED.
Example
In this example, dbordercol(dbproc, 1) returns 3 since the first column named in the ORDER BY clause refers to the third column in the SELECT statement:
SELECT dept, name, salary FROM employee
ORDER BY salary, name
