Select with no lock should allow results to be returned - though it will effectively be a dirty read.

I would consider implementing such locking a bug not a feature. Try the following in SQL server query analyzer: Begin Tran [some update of a table] in new window try to select on the table and do some other ops. See what happens. After you are done do 'commit' in transaction window or 'rollback'. Depending on locking you wil need to commit or rollback trans before you can see anything done by select TK > >>cftransaction locks that DB actually follows may lock the whole table > and > you should *never* place any user code or some prolonged operation inside > transaction block. > > cftransaction is not a panacea either: it only locks for the time of a > transaction, > not for the time the user will edit a record. > > -- > _______________________________________ > REUSE CODE!
