RE: SQL HELP

Try this (lines I added or changed are denoted by C++, change them back to C+). If it doesn't work
you may want to build and prepare your statement dynamically:

C/exec sql
C+ DECLARE R2CSR CURSOR FOR
C+
C++ WITH Temp as (
C+ SELECT MPMRS, CLSUPR, ROUND(AVG(NULLIF(A1,0)),0) AS A1,
C+ ROUND(AVG(NULLIF(A2,0)),0) AS A2, ROUND(AVG(NULLIF(A3,0)),0) AS A3,
C+ ROUND(AVG(NULLIF(A4,0)),0) As A4, ROUND(AVG(NULLIF(A5,0)),0) AS A5
C+
...
C+
C++ Group By mpMrs,CLSUPR )
C++
C++ Select * from Temp
C+ ORDER BY
C+ (Case When :WKSTARDSC = 'OVERALL AVERAGE' Then A1
C+ When :WKSTARDSC = 'i5 SCREEN TIME' Then A2
C+ When :WKSTARDSC = '# OF ACCOUNTS ATTEMPTED' Then A3
C+ When :WKSTARDSC = '# OF TOTAL INSTRUMENTS' Then A4
C+ When :WKSTARDSC = '# OF SCREENS COMPLETED' Then A5 End) DESC
C/end-exec

The suggestion was not to remove the A, but to tell it which result set
column number to sort on. For
example, A1 is column 3 in your SQL.

in the order clause, removing the "A" from a1, a2, a3, a4, and a5 allows
the program to compile but does not allow the sorting to occur like it
should when i run the pgm... so what else?

Sorting by derived columns often necessitates a Common Table Expression or
CTE, or, change
C+ (Case When :WKSTARDSC = 'OVERALL AVERAGE' Then A1
to
C+ (Case When :WKSTARDSC = 'OVERALL AVERAGE' Then 3
And the 3 will be the third column in the selection. I prefer CTE's in
case someone adds a new selection field. Then it's more documenting then
positional.

If we trim this down to:
C/exec sql
C+ DECLARE R2CSR CURSOR FOR
C+
C+ SELECT MPMRS, CLSUPR, ROUND(AVG(NULLIF(A1,0)),0) AS A1,
C+ ROUND(AVG(NULLIF(A2,0)),0) AS A2, ROUND(AVG(NULLIF(A3,0)),0) AS A3,
C+ ROUND(AVG(NULLIF(A4,0)),0) As A4, ROUND(AVG(NULLIF(A5,0)),0) AS A5
C+
...
C+
C+ Group By mpMrs,CLSUPR
C+ ORDER BY
C+ (Case When :WKSTARDSC = 'OVERALL AVERAGE' Then A1
C+ When :WKSTARDSC = 'i5 SCREEN TIME' Then A2
C+ When :WKSTARDSC = '# OF ACCOUNTS ATTEMPTED' Then A3
C+ When :WKSTARDSC = '# OF TOTAL INSTRUMENTS' Then A4
C+ When :WKSTARDSC = '# OF SCREENS COMPLETED' Then A5 End) DESC
C/end-exec
