Does anyone know where I can find the 'official' definition of what it meant by ACID compliance? We're having a discussion about it that we could do with resolving. In particular, the key point is what it meant by the 'C' part. I maintain that MySQL is not ACID compliant because it will (among other things) swallow integers that don't fit into a column silently and just truncate it, while our DBA (while agreeing that this is not good behaviour) maintains that this is not what the C part means: he says that's just about transaction states (succeed or fail etc). Anyone have a link? Thanks. -- Russ
