"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!":

C:\herong>\local\mysql\bin\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.
