Thread: reusing column labels in select
Hello, Is there any way to reuse a column label in a select list like this: SELECT 1 + 1 AS a, a + 1 AS b; I vaguely remember being able to do something like this in oracle. Any ideas? Thanks! ~RvR
There might be a better way then this but this works SELECT a, a+1 as b from (SELECT 1+1 as a) as ab; On 16 Oct 2004 11:18:48 -0700, ryan <rvanroode@gmail.com> wrote: > Hello, > > Is there any way to reuse a column label in a select list like this: > > SELECT 1 + 1 AS a, a + 1 AS b; > > I vaguely remember being able to do something like this in oracle.
