Dmitry, I used an empty database made with backup/restore from 2.5.6 to 3.0.1. I did this step many times and this is the only one with this issue. I will inform you, when this happens again. -- Best regards, TRoland http://www.rotursoft.sk http://exekutor.rotursoft.sk

A generator that has never been triggered has a value of 0, not 1. In the context of your complaint that NEXT VALUE FOR seemed to return a wrong value, Dmitry suggested you query the column RDB$GENERATOR_INCREMENT in RDB$GENERATORS, to check whether the problem might be caused by 0 or null in that field. If you didn't do that, and you think you still have a problem, then look at it. HB

Re: [firebird-support] Re: NEXT VALUE FOR on Firebird 3.0.1 32bit Windows 7 32bit
Hello Dmitry, Thanks for response, but I have found that he has only few generators with value 1. But I cannot call this: update RDB$GENERATORS set rdb$generator_increment = 1 where rdb$generator_name not starting 'RDB$'; how can I set the value to 1? Thanks.

Is that > intentional? System generators are not transferred in backup, they're recreated from scratch when a database is being created during restore. And you cannot explicitly issue either GEN_ID or NEXT VALUE for them, the engine itself increments them at the low level, without looking at RDB$GENERATOR_INCREMENT. So I believe it's absolutely OK, although possibly looking weird. Dmitry

NEXT VALUE FOR uses > the increment stored inside the system table. I noticed something interesting, when restoring a Firebird 2.5 database to Firebird 3.0, only user generators (RDB$SYSTEM_FLAG = 0) get a value of 1 in RDB$GENERATOR_INCREMENT, system generators get 0. Is that intentional? Mark -- Mark Rotteveel

Check RDB$GENERATOR_INCREMENT inside RDB$GENERATORS. NEXT VALUE FOR uses the increment stored inside the system table.
