How to correctly use DELIMITER in a MySQL stored procedure?
The correct way is as follows −
DELIMITER // CREATE PROCEDURE yourStoredProcedureName() BEGIN IF yourCondition then yourStatement1 ; else yourStatement2 ; END IF ; END // DELIMITER ;
Let us now see an example and create a stored procedure −
mysql> DELIMITER // mysql> CREATE PROCEDURE delimiter_demo() -> BEGIN -> IF 1 THEN -> SELECT "If condition will always true"; -> else -> select "No" ; -> END IF ; -> END -> // Query OK, 0 rows affected (0.17 sec) mysql> DELIMITER ;
Now you can call the stored procedure using CALL command
mysql> call delimiter_demo();
This will produce the following output −
+-------------------------------+ | If condition will always true | +-------------------------------+ | If condition will always true | +-------------------------------+ 1 row in set (0.00 sec) Query OK, 0 rows affected (0.02 sec)
