Plugins/Artefact/My Learning/Uninstalling

For uninstalling plug-in you need admin access to your mahara root directory and to your MySQL or PostgreSQL database. I use MySQL database and SQLyog (which is a GUI for working with MySQL database - see images below).

NB: All tables in my database have mhr_ prefix, so in attached images you'll see all tables with mhr_ prefix!

To uninstall My Learning plug-in, follow these simple steps:

1. Connect to your database (MySQL or PostgreSQL)
    
2. Delete all lines from table blocktype_installed_viewtype, which contain learningstyles or multipleintelligences. Use appropriate SQL sentences:
   
   DELETE FROM blocktype_installed_viewtype WHERE blocktype='learningstyles';
DELETE FROM blocktype_installed_viewtype WHERE blocktype='multipleintelligences';
    
3. Delete all lines from table blocktype_installed_category, which contain learningstyles or multipleintelligences. Use appropriate SQL sentences:
   
DELETE FROM blocktype_installed_category WHERE blocktype='learningstyles';
DELETE FROM blocktype_installed_category WHERE blocktype='multipleintelligences';
    
4. Delete all lines from table blocktype_installed, which contain learningstyles or multipleintelligences. Use appropriate SQL sentences:
   
DELETE FROM blocktype_installed WHERE name='learningstyles';
DELETE FROM blocktype_installed WHERE name='multipleintelligences';
    
5. Delete all lines from table artefact, which contain learningstyles or multipleintelligences. Use appropriate SQL sentences:
   
DELETE FROM artefact WHERE artefacttype='multipleintelligences';
DELETE FROM artefact WHERE artefacttype='learningstyles';
    
6. Delete all lines from table artefact_installed_type, which contain learning. Use appropriate SQL sentence:
   
DELETE FROM artefact_installed_type WHERE plugin='learning';
    
7. Delete all lines from table artefact_installed, which contain learning. Use appropriate SQL sentence:
   
DELETE FROM mhr_artefact_installed WHERE name='learning';

All this can be also acomplished just by using SQLyog or similar GUI - please see the attached pictures below.

Sorry, I don't know any GUI to use with PostgreSQL (since I don't use it).
