What does the "%%" in this statement mean?
SELECT nextval(seq_name) %% 1024 INTO seq_id;
And why does Postgres say, when I use it?
operator does not exist: bigint %% integer
Most probably, it's an artifact from translating dynamic SQL with format()
, which requires to double %
characters. Should be the modulo operator %
if translated correctly, which also makes sense for a sharding solution or similar. Effectively, you get numbers cycling from 0 to 1023.
I suspect it's the same as we already dealt with here:
