I have two tables EventsLog and FaultsLog, FaultsLog has a foreign key to EventsLog and I run this queries
select EventsLog.PK from TVM.dbo.EventsLog where PK = 1095387
select FaultsLog.PK, FaultsLog.fkEventsLog from TVM.dbo.FaultsLog where FaultsLog.fkEventsLog = 1095387
select EventsLog.PK from TVM.dbo.EventsLog where EventsLog.PK not in (select FaultsLog.fkEventsLog from tvm.dbo.FaultsLog)
First query returns one record, all is good.
Second query returns no records, still good.
Third query returns no records too?? Shouldn't I get the record for PK = 1095387?
So confused...
(By the way, this is part of a longer store procedure that was working fine until Friday, today I noticed the problem and I think I narrowed it down to a query similar to this)
TIA,
Hugo
