And what's the result of: select i.rdb$relation_name , s.rdb$field_name from rdb$indices i join rdb$index_segments s on (i.rdb$index_name = s.rdb$index_name) where i.rdb$index_name = 'RDB$INDEX_20' Regards, Thomas > Greetings from Lutherstadt Wittenberg :-) > Maik Sommer > IT-Systemadministrator > > > > processed by David.fx > Subject: Re: [firebird-support] Restore fails due to "duplicate Value in > unique Index" (13-Sep-2012 14:03) > From: Thomas Steinmaurer <t...@iblogmanager.com> > To: firebird-support@yahoogroups.com > > > >> i have a problem with my 27Gb FB2.5 Database.
