Creating Procedures with INOUT Parameters
This section describes how to create a procedure with INOUT parameters.
To do more tests on CallableStatement objects, I created another stored procedure with INOUT parameters:
herong> local\mysql\bin\mysql -u Herong -pTopSecret mysql> USE HerongDB; Database changed mysql> -- Changing the command delimiter to '$' mysql> DELIMITER '$'; mysql> -- Creating the procedure mysql> CREATE PROCEDURE C2F(INOUT C REAL, INOUT F REAL) -> BEGIN -> IF C IS NOT NULL THEN -> SET F = 1.8*C + 32.0; -> ELSEIF F IS NOT NULL THEN -> SET C = (F-32.0)/1.8; -> ELSE -> SET C = 0.0; -> SET F = 32.0; -> END IF; -> SELECT C, F; -> END$ Query OK, 0 rows affected (0.00 sec) mysql> -- Testing the procedure mysql> SET @C = 20$ Query OK, 0 rows affected (0.00 sec) mysql> CALL C2F(@C,@F)$ +------+------+ | C | F | +------+------+ | 20 | 68 | +------+------+ 1 row in set (0.00 sec) Query OK, 0 rows affected (0.00 sec) mysql> -- Checking output parameters mysql> SELECT @C, @F$ +------+------+ | @C | @F | +------+------+ | 20 | 68 | +------+------+ 1 row in set (0.00 sec)
