~ I looked in the archive for anything about "SQL schema", but there were just two messages, and the original message had no thread with it.
~ I took your suggestion, and tried the following, but got the same error message: INSERT INTO comments (idx,sourceid,created,userid,comment,parentid) VALUES(0,1,NULL,'testuser','this is a test',(SELECT max(idx) FROM comments WHERE sourceid=1))
~ The error is still: You can't specify target table 'comments' for update in FROM clause
