How to insert/create stored procedures in mySQL from PHP?

Question

I\'ve got a number of stored procedures made with the MySQL Workbench. They work just fine when use MySQL workbench to put them into my test DB.

Now I am preparing

Answer 1

DELIMITER is something that the mysql client application actually uses. I believe that the client application is responsible for breaking up the queries that it sends to Mysql. That is what PHPMyAdmin does, for example.

Instead of spending a whole night writing a script to parse MySQL into queries, use the code I wrote. You will find it in the scriptToQueries function, here:

ENJOY

EDIT: Since writing this answer I have ported the code into the free Q platform in which you can study the code: https://github.com/EGreg/Platform/blob/master/platform/classes/Db/Mysql.php#L824

Answer 2

I haven't tested, but I won't be surprised by mysqli_multi_query() expecting to have the same delimiter of each queries. Try to pack the stored procedure creation in a single query, without using the DELIMITER modifier ?

So instead of

<?php
$results = mysqli_multi(
    'DELIMITER $$
    USE `dbname`$$
    CREATE PROCEDURE `procname`(IN inputparameters)
    BEGIN
    ... procedure goes here

    ;
    END$$
    DELIMITER ;
');
?>

Just do this

<?php
$result = mysqli_query('CREATE PROCEDURE `procname`(IN inputparameters) BEGIN ...; END');

And tell us if it works :)

Answer 3

To sum it up:

DELIMITER is implemented client-side, not serverside.

If you have a good driver or API, it may take care of this. PHP mysql / mysqli, as of now, do not.

If you need to use a different delimiter (e.g. because the default delimiter appears inside scripts), you have to encode/escape your SQL yourself or break it up so you don't need to change the delimiter. No help from PHP here.
