I have spent a good portion of today trying to create an image of the MediaWiki table structure.
While I think the SQLFairy (aka SQL Translator) is going to work quite well, it has rather cryptic error messages.
For instance, if the SQL syntax isn’t supported by its internal parser, the error message references the start of the table.
Which means, of course, that you have to compare statements in the table to the subset of SQL that is supported.
I am rapidly losing my SQL parsing skills as the night wears on so I am stopping with a little over 50% of the MediaWiki schema parsing.
Hopefully will finish correcting the SQL file tomorrow and will post the image of the MediaWiki schema.
Plus notes on what I found to not be recognized in SQLFairy to ease your use of it on other SQL schemas.
