oh magic eight ball is there a better way than calling a ugly function twice
when I need two columns returned with the same value.
I hate the call the function twice because it is very costly.
what I need to do is:
select x,y,z, ugly_function as ugly1, ugly_function ugly2 from a
when I do.... it actually gives me worse results ie. more physical reads....
select x,y,z , ugly1, ugly1 as ugly2 from (
select x,y,z, ugly_function ugly1 from a)
Is there anyway around this?
Kathy.
