(part+1)*[colnum] The actual formula I want to use is: `index` = (30 * part) + [colnum] The problem is I don't know how to implement this in an SQL statement - what I want is something like an INSERT...SELECT which can split the SELECTed columns of a single row (id, c1, c2, c3) into multiple rows in the INSERT: (id, 1, c1), (id, 2, c2), (id, 3, c3). Afaik there is no such thing so I need an equivalent method - one that isn't going to kill my server (like the several attempts I've made so far!) --Rob ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
