I would expect > him to get the message 'DELETE 1'. Why do you find that strange? Process 1 hasn't committed its insert yet.
I think what he is saying that *after* txn 1 commits, txn 2 does not see the record inserted by txn1. Isn't that a fair point ? I mean txn 2 can see the DELETE operation of txn 1, but can not see the INSERT operation of the same transaction. Thanks, Pavan -- EnterpriseDB http://www.enterprisedb.com
