I have developed a Joomla extension and in the newest version the need to delete one column from a table belonging to my plugin has arisen.
As far as I know there is no easy way to delete a column in Mysql only if it exists. Therefore, the only possibility I see at the moment to achieve that, would be to use custom php upgrade code, as shown here.
But this problem would seem so common to me, that I would suspect to be an easier solution? Is there maybe an easy way (provided through Joomla) to execute a schema change only when updating from a particular extension version?
