How to quit/ exit from MySQL stored procedure?

We can quit/ exit from MySQL stored procedure with the help of the LEAVE command.

The following is the syntax.

Leave yourLabelName;

The following is an example. Here, we are creating a new procedure.

mysql> delimiter //
mysql> CREATE PROCEDURE ExitQuitDemo2(IN Var1 VARCHAR(20))
   -> proc_Exit:BEGIN
   -> IF Var1 IS NULL THEN
   -> LEAVE proc_Exit;
   -> END IF;
   -> END //
Query OK, 0 rows affected (0.16 sec)

Above, we have set the following LEAVE command to exit from the procedure. If Var1 is “NULL”, the procedure will exit.

LEAVE proc_Exit;

To change the delimiter to ‘;’.

mysql>delimiter ;

To call stored procedure, we need to use CALL command followed by the procedure name.

The following is the syntax.

call yourStoredProcedureName;
