CLOSE

Syntax:

>>---EXEC SQL---.------------.--->
                +-AT db_name-+

 >--CLOSE---cursor_name---.------------.---END-EXEC---><

Parameters:

AT `db_name`	The name of a database that has been declared using DECLARE DATABASE. This clause is not required, and if omitted, the connection automatically switches to the connection associated with the DECLARE CURSOR statement if different than the current connection, but only for the duration of the statement. Provided for backward compatibility.
`cursor_name`	A previously declared and opened cursor.

Comments:

The cursor must be declared and opened before it can be closed. All open cursors are closed automatically at the end of the program.

Example:

*Declare the cursor...
     EXEC SQL
         DECLARE C1 CURSOR FOR
            SELECT staff_id, last_name
            FROM staff
     END-EXEC

     IF SQLCODE NOT = ZERO
        DISPLAY 'Error: Could not declare cursor.'
        DISPLAY SQLERRMC
        DISPLAY SQLERRML
        EXEC SQL DISCONNECT ALL END-EXEC
        STOP RUN
     END-IF
     
     EXEC SQL
        OPEN C1
     END-EXEC

     IF SQLCODE NOT = ZERO
        DISPLAY 'Error: Could not open cursor.'
        DISPLAY SQLERRMC    
        DISPLAY SQLERRML
        EXEC SQL DISCONNECT CURRENT END-EXEC
        STOP RUN
     END-IF

     PERFORM UNTIL sqlcode NOT = ZERO
*SQLCODE will be zero as long as it has successfully fetched data
        EXEC SQL
           FETCH C1 INTO :staff-staff-id, :staff-last-name
        END-EXEC
        IF SQLCODE = ZERO
           DISPLAY "Staff ID: " staff-staff-id
           DISPLAY "Staff member's last name: " staff-last-name
        END-IF
     END-PERFORM

     EXEC SQL
        CLOSE C1
     END-EXEC

     IF SQLCODE NOT = ZERO
        DISPLAY 'Error: Could not close cursor.'
        DISPLAY SQLERRMC
        DISPLAY SQLERRML
     END-IF
