Question

I have a query with the following syntax:

select x.a as a, x.b as b, x.c as c
from
  (select distinct a from foo
     order by y) as x
  left join zzz....
  left join yyy...;

I want to now put in an order by into the outer select statement.

attaching it to the end – it doesn’t like the syntax, and putting it before the as is apparently valid syntax, but returns an empty result set, when omitting the order by certainly returns results.

Any theories?

Sorry about the variable names, but they’re not really important – it’s more about the placement of the order by that I’m concerned.

Answer 1

The Order By comes after the Where in the outer Select. If there is no “Where” then you’ll place it after the last On (X=X) selector in your join.
