OLE DB CLOSE

If a database stored procedure returns a result set, you must close the stored procedure when processing is complete. The procedure remains open until you close it, execute a COMMIT or ROLLBACK, or end the database connection.

Do you have to retrieve all the rows?

You do not have to retrieve all rows in a result set to close a request or procedure.

Example

Closing a procedure looks the same as closing a cursor:

CLOSE emp_proc;
