Re: Sql question about join order

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

A couple comments -

I couldn't tell if the OP wanted only the last row or to start with it - 
in either case, DESC is the thing to use, as all the replies have suggested.
A couple replies have offered what looks like 2 solutions - DESC LIMIT 1 
--or-- DESC FETCH FIRST 1 ROW -- they mean the same thing. According to 
the SQL Reference, LIMIT and OFFSET were added in October 2015. Here is 
an interesting comment on this -

I also saw a comment that OFFSET can't be used in interactive SQL, 
didn't see anything about that restriction for LIMIT.
