Thread: How to obtain a sequence's increment value from the system catalog

How to obtain a sequence's increment value from the system catalog

Hi,

I'd like to query a sequence's increment value from the system catalog. I tried looking at http://www.postgresql.org/docs/8.1/static/catalog-pg-class.html but I'm stuck here.

Any ideas/help would be appreciated.

Thanks,

Wouter Gazendam
have you tried:
select * from my_seq;

or are you looking for the functions currval() or lastval()

Ah, 'select * from my_seq;' did the trick.
I mistakenly assumed that all information entered in DDL statements would end up in the system catalog.

Thank you for the quick response,
