chamilo-lms/main/install/migrate-db-1.6.x-1.8.0-post.sql

-- This script updates the databases structure before migrating the data from
-- version 1.6.x to version 1.8.0
-- it is intended as a standalone script, however, because of the multiple 
-- databases related difficulties, it should be parsed by a PHP script in
-- order to connect to and update the right databases.
-- There is one line per query, allowing the PHP function file() to read 
-- all lines separately into an array. The xxMAINxx-type markers are there 
-- to tell the PHP script which database we're talking about.
-- By always using the keyword "TABLE" in the queries, we should be able
-- to retrieve and modify the table name from the PHP script if needed, which
-- will allow us to deal with the unique-database-type installations

-- This first part is for the main database
