"CREATE PROCEDURE" - Creating a Simple Procedure
This section describes how to create a simple procedure that runs a simple query.
In order to test CallableStatement objects, I created a very simple stored procedure that runs a query to return "Hello world!":
herong> mysql -u Herong -pTopSecret
mysql> USE HerongDB;
Database changed
mysql> DELIMITER '/';
mysql> CREATE PROCEDURE HelloWorld()
-> BEGIN
-> SELECT 'Hello world!' AS Message;
-> END/
Query OK, 0 rows affected (0.00 sec)
mysql> CALL HelloWorld()/
+--------------+
| Message |
+--------------+
| Hello world! |
+--------------+
1 row in set (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
Note that "DELIMITER '/';" was used to change the command delimiter from ";" to "/", so that I can use ";" as part of the stored procedure definition statement.
"CALL HelloWorld()/" is a command to test the stored procedure.
If you make a mistake in the stored procedure, you can delete it from the server by the "DROP PROCEDURE HelloWorld" command.
