Hi all

According to page 159 of Certfox, a .DBC record is locked when a view is requeried AND this lock prevents others from doing a query until the results are returned. If that's true, it should be demonstrable with only 2 users and a query against a large table returning lots of records.

So, I tried it. Query progress bars were active on both machines, but if I interpret CertFox correctly, one machine should have had to wait.

It should be possible to show record contention with 2 users. Anyone have any code that could demonstrate this?
