Re: [GENERAL] sequence

Hi Tom,

but when i let pgsql setup everything (i mean when i create table -> pgsql creates sequence)
), i have called = no, before using any select nextval()... and in this case, it works great.

but once called = yes, select nextval(sequence_name); always gives me current value +1 :-(
