Thomas Fox resolved TORQUE-281. ------------------------------- Resolution: Won't Fix Assignee: Thomas Fox A database is in principle a device where many users can write to. This means a row in the database can be written by a concurrent connection at any time. There are two ways known to me to be sure that all columns of a row are in the desired state a) write all rows b) put a write lock on the row while reading and then write only the changed columns Torque has always chosen the method a). It may be a bit slower but it is simple. b) has the problem that a lock is put on a row, which can cause problems like when to lock a row, dealing with unreleased locks, deadlocks etc. > Only issue SQL update with columns whose value is changed in dbObject, since > it was loaded from db > -------------------------------------------------------------------------------------------------- > > Key: TORQUE-281 > URL: https://issues.apache.org/jira/browse/TORQUE-281 > Project: Torque > Issue Type: Improvement > Reporter: rajguru > Assignee: Thomas Fox > > This means dbObject needs to have a way to see oldValue and newValue.
