Обсуждение: grouping and first()

Hi, just wondering if anyone can tell me what replaces the first  function
in access.


Thanks

PEter

select first(a) from ta order by a

in access, is equivilent to

select a from ta order by a limit 1

Thanks
Chad
P.S.  Note that access will always return the same value if you exclude the
order by, this is not necessarily true with postgresql or any real RDBS.
