Hi, This look for me like wrong design. Query running minutes are not acceptable from my POV.
I do not know how your system work, but in any stock system i see month work. Month is closed and data are calculated and stored. And in next month the same Regards, Karol Bieniaszewski ----- Reply message ----- Od: "'Tiberiu Horvath' tiberiu_horv...@yahoo.com [firebird-support]" <firebird-support@yahoogroups.com> Do: <firebird-support@yahoogroups.com> Temat: [firebird-support] Cumulative queries Data: czw., mar 12, 2015 07:19 Hi all, I have a Firebird stock management system with 100+ tables and 10+ clients. I have some cumulative queries in my Delphi program that generates reports. My problem is that while the queries are run (less than 5 minutes each), the whole system performance is poor, people complaining about the speed of the database. How do you deal with this ? Thinking about : 1. Create a backup database and have the queries run there (backup / restore during the night) ? This would be the obvious option. If data for the reports is one day behind the real system is not a big problem. 2. In FireBird do I have some switch to lower the priority of a query ? select * from table –low priority mode- some other ideas ? Thank you in advance , Tiberiu
