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)
