Creating Procedures with IN and OUT Parameters
This section describes how to create a procedure with IN and OUT parameters.
To do more tests on CallableStatement objects, I created another stored procedure with IN and OUT parameters:
herong> mysql -u Herong -pTopSecret mysql> USE HerongDB; Database changed mysql> -- Changing the command delimiter to '/' mysql> DELIMITER '/'; mysql> -- Creating the procedure mysql> CREATE PROCEDURE ReverseProcedure(IN String VARCHAR(80), -> OUT Reversed VARCHAR(80), OUT Length INTEGER) -> BEGIN -> SET Reversed = REVERSE(String); -> SET Length = LENGTH(String); -> SELECT String, Reversed, Length; -> END/ Query OK, 0 rows affected (0.00 sec) mysql> -- Testing the procedure mysql> CALL ReverseProcedure('Herong', @Reversed, @Length)/ +--------+----------+--------+ | String | Reversed | Length | +--------+----------+--------+ | Herong | gnoreH | 6 | +--------+----------+--------+ 1 row in set (0.00 sec) Query OK, 0 rows affected (0.00 sec) mysql> -- Checking the OUT parameters mysql> SELECT @Reversed, @Length/ +-----------+---------+ | @Reversed | @Length | +-----------+---------+ | gnoreH | 6 | +-----------+---------+ 1 row in set (0.02 sec)
