I am using the following code for creating tables in my .sql file as part of a module.

CREATE TABLE IF NOT EXISTS `#__gruposlocales` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `name` varchar(255) NOT NULL,
    `latitude` float(10,6) NOT NULL DEFAULT '255.000000',
    `longitude` float(10,6) NOT NULL DEFAULT '255.000000',

  PRIMARY KEY (`id`)

INSERT INTO `#__gruposlocales` (`id`, `latitude`, `longitude`) SELECT userid, latitude, longitude FROM `#__community_users`;
INSERT INTO `#__gruposlocales` (`name`) SELECT name FROM `#__community_groups` WHERE id=ownerid;

However, when I try to install the module, I get this error:

JInstaller: :Install: Error SQL Unknown column 'latitude' in 'field list' Extension Install: SQL error processing query: DB function failed with error number 1054 Unknown column 'latitude' in 'field list' SQL = INSERT INTO `#__gruposlocales` (`id`, `latitude`, `longitude`) SELECT userid, latitude, longitude FROM `#__community_users`;

Is my code wrong? Could anybody help to fix this, please?

    The table you select from has a latitude field? Mar 1 '18 at 5:54
  • Yes, @SvenBluege, one of the table I select from has the following fields: userid, latitude, and longitude. The code works perfectly inside of phpmyAdmin, creating the requested table from those two other tables. Mar 1 '18 at 13:27
  • Has your database user more than one joomla installation? Did you use the right replacement for #__ while running it in phpmyadmin? Another Idea: bugs.mysql.com/bug.php?id=1689 Mar 1 '18 at 16:37
  • Thank you, Sven. Yes, there a more than one Joomla installation and yes I used the #_jos fashion. I read the article you kindly pointed me out. I have followed every suggestion but I get the same error. As for the grave accents instead of straight quote marks, I have this code that works well with no complains: INSERT INTO #__helloworld (hello, lang) VALUES ('Hello World', 'en-GB'); INSERT INTO #__helloworld (hello, lang) VALUES ('Hola Mundo', 'es-ES'); INSERT INTO #__helloworld (hello, lang) VALUES ('Bonjour tout le monde', 'fr-FR'); Mar 1 '18 at 23:10
  • The grave accents are not visible and I don't know how to fix it. Mar 1 '18 at 23:17

Your database contained more than one Joomla table set. The install script got confused by that.

  • I think for the green tick, this answer needs a bit more context from the string of comments. Please write a comprehensive answer that can stand alone in case comments are deleted.
