Stored procedures are used to store some actions on your database. So that those actions can be peformed by people without having direct access to the data.

It allows for variable declaration. Its like functions in programming.


CREATE PROCEDURE `multiply` (OUT var1 INT)
    SET var1 = var1 * 2;
END //

When the mutiply procedure is called like so

CALL multiply(5)

its given a parameter(in this case 5).

That parameter is then multiplied by two and returned.

Within the "begin" and "end", you can put any type of query.

It limits what users can do on your database and enhances security and ease of use.

The "DELIMITER" tells sql your done with typing a statement.

In the example we used // as our delimiter.

Hope that helps.

Very Thanx,
