Creating stored procedures with Joomla Custom Installer code API

Question

Update: [Background info: I'm working on a Silverlight app which uses PHP code to interact with the MySql dbase. I have a regular installation package on www.mobilesportscoach.com (demo site on www.mobilesportscoach.com/test) which works well when you run the SQL file in phpMyAdmin. But I want the whole package to be installable in Joomla without having people to run several scripts in several places.]

I'm creating an joomla components xml install file and in the install section I want it to create my tables / stored procedures with an sql script so I've tried:

    <install> 
     <sql> 
      <file charset="utf8" driver="mysql">install.sql</file> 
     </sql> 
     <install>

Tables aren't the problem, single line sql code runs fine but in my SQL create procedure statements I have to change the delimiter (that's how it works in MySQL), eg:

    DELIMITER $$
    CREATE PROCEDURE `tp_delete_match_and_scores_onmatchid`(IN matchid VARCHAR(10))
    BEGIN
     DELETE FROM tp_scores WHERE (tp_scores.matchid=matchid);
     DELETE FROM tp_matches WHERE (tp_matches.recid=matchid);
    END$$
    DELIMITER ;

The extension installer gives me:

   JInstaller: :Install: Error SQL DB function failed with error number 1064 
  You have an error in your SQL syntax; check the manual that corresponds to your MySQL
  server version for the right syntax to use near 'DELIMITER $$ 

I've also tried the custom installer api but I can't get it to work: I have an installfile tag in my xml: install.component.php

My php:

 <?php
function com_install(){
global $database;

 echo  "TEST COM_INSTALL";

 //get database
 if(defined('_JEXEC')){
  //joomla 1.5
  $database = JFactory::getDBO();
 }   

 //table for item index
  $query = "CREATE PROCEDURE `tp_delete_match_and_scores_onmatchid`(IN matchid VARCHAR(10)"; 
  $query .= "\nBEGIN"; 
  $query .= "\nDELETE FROM tp_scores WHERE (tp_scores.matchid=matchid);"; 
  $query .= "\nDELETE FROM tp_matches WHERE (tp_matches.recid=matchid);";
  $query .= "\nEND"; 

  $database->setQuery($query);
  $database->query();

  ?>

The component installs alright but I can't find my procedure with phpMyAdmin / is not created. Seems like the install.component.php isn't fired at all?

I don't want users to run a separate sql script, I want it all in one package if possible...

Answer 1

Have the same question and found this about the manifest XML files:

http://docs.joomla.org/Manifest_files#Script_file

There's a section "Script file" describing what you need. You have to create a special class in your custom installer script.

One common thing is to change keyword 'TYPE' to 'ENGINE' (for MySQL 5.5.x) but sometimes it still doesn't work...

Make sure your install.sql file is formatted/codded in UTF-8 WITHOUT BOM!!
