Hi, (This is Firebird 1.5.3)
I have an 'empty' database with a 'prefs' table which has a pk
'prefs_sn', and a generator 'gen_prefs' which is initially set to 1.
I have a routine which copies all rows of the prefs table from one DB
into another (ALL columns, including the pk's).

When I'm complete I need to set the generator to max(prefs_sn)+1 so
here's my statement:

SET GENERATOR GEN_PREFS TO (select (case when max(PREF_SN) is null
then 1 else max(PREF_SN)+1 end) from PREFS)

However I'm running into trouble after "SET GENERATOR GEN_PREFS TO " -
it seems I can only make it work if I hard-code the value, i.e it
doesn't like me having the inner select there (error is 'Invalid token
select...').

How do I get the system to update the next number in the generator
(there's probably a simpler way than I tried!)?

Thanks, Phil
