Hi,
When we use WITH (NOLOCK) at the end of table list in a SELECT query, a Cartesian join is returned (i.e. approximately 6,500 records instead of 57, which is distressing.
We are building a database-agnostic system; while I believe PostgreSQL is using a multiversion locking model and does not need WITH (NOLOCK), our application also must run against MS SQL Server and that uses a concurrency control locking model. We are using PostgreSQL 7.3.2 on RedHat 7.2.
Any suggestions?
Thanks in advance,
Roger
