[firebird-support] Cannot restore a database because of failed unique key index
Hi, We use Firebird 2.5.1 on Linux 64 bit Firebird fails to restore because of a unique constraint( see below ). However when interrogating the data, no duplicate is found. ( see below SQL, unique key is on the grouped by fields ) How can this be? Kind Regards, Robert.

Hello, Your query uses index, which is correct (it contains unique values). Try to run this query on partially restored database.

Your query above probably uses that index, thus you won't see any result set. Executing the query without that index, probably show duplicates then. -- With regards, Thomas Steinmaurer http://www.upscene.com/

Your query needs an aggregate field. Count.
