Hi,
I am trying to issue a query like "SELECT * from <some table> limit
30". In psql command line interface it displays only 30 rows at a time.
How will it behave if I use libpq. Is it going to return me only 30 rows ?
Regards,
Kashyap Jani

With LIMIT 30 psql should display only 30 rows altogether ("30 rows
at a time" suggests that you're getting more than 30 rows -- are
you?).

If you put LIMIT 30 in the query then you should get at most 30
rows. What happened when you tried it?

Thanks Michael,
I returned 30 records back. I wasn't sure how it will work and
thought I could just ask instead of actually writing a sample test
program... But I ended up witting a sample program anyway..
