(Thomas Corell T.Corell@t-online.de): But, I will start porting the tables as soon I found some spare time. Lee, is there a loctation where I can get these mysql statements you isolated?
All database access in the system should go through the functions in DatabaseFunctions.php. The only one that might be tricky to implement is wfInsertID(), which currently depends on a MySQL extension for auto-increment fields. But most databases have some similar feature.
