RE: SQL scroll cursor slow performance

If you insist on SQL, basic Boolean logic still helps:

> From: darren@xxxxxxxxx
> 
>      C*        multiply by duty rate percentage
>      C+          ifnull(case
>      C+            when :FEDATE>=F4COOD
>      C+              then 0
>      C+            when :FEDATE<F4COOD
>      C+              and FLPROF='Y'
>      C+              then FLPROR
>      C+            when :FEDATE<F4COOD
>      C+              and FLPROF<>'Y'
>      C+              then FLNORR
>      C+            end,0)

Can be replaced by this:

     C*        multiply by duty rate percentage
     C+          ifnull(case
     C+            when :FEDATE>=F4COOD
     C+              then 0
     C+            when FLPROF='Y'
     C+              then FLPROR
     C+            else FLNORR
     C+            end, 0)

I'm not sure of the effect on performance; it would depend on how smart
the SQL engine is.
