We use DTS packages to compile scripts needed to upgrade our databases. This has worked fine until today so I believe this is related to all of the MS released security patches this week. I can isolate the problem to the SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement that SQL Compare places in the migration script. If I comment it out then all works fine. I assume this more restrictive setting is preferred, so are there any ideas how to get that isolation level to work again?
