RE: SQL - Using Case in Order By clause

["Hauser, Birgitta" <Birgitta.Hauser@xxxxxxxxxxx>]

Hi Terri,

C/EXEC SQL DECLARE A CURSOR FOR
C+ SELECT EMEMP#,EMPNAM,EMSTCD,EMOHYY,EMCORP,EMPAY#
C+ FROM HRV6DTA/HRPEMP
C+ ORDER BY Case  When :F1Sort = 'Y' then EMEMP#
C+                      When :F1Sort = 'N' then EMLNAM ConCat EMFNAM
C+                      End
C/END-EXEC

Your solution only will work if EMEMP# is a character field, too.
To handle different datatypes, you have to use different Case statements.
See the following example:
I suppose that EMEMP# and EMLNAM have different formats, may be character
and numeric.

C/EXEC SQL DECLARE A CURSOR FOR
C+ SELECT EMEMP#,EMPNAM,EMSTCD,EMOHYY,EMCORP,EMPAY#
C+ FROM HRV6DTA/HRPEMP
C+ ORDER BY Case  When :F1Sort = 'Y' then EMEMP#
C+                Else NULL
C+          End,    
C+          Case  When :F1Sort = 'N' then EMLNAM 
C+                Else NULL
C+          End,
C+          Case  When :F1Sort = 'N' then EMFNAM
C+                Else NULL   
C+          End
C/END-EXEC

If EMEMP# and EMLNAM have the same format, may be both Character, the
example can be changed as follows:

C/EXEC SQL DECLARE A CURSOR FOR
C+ SELECT EMEMP#,EMPNAM,EMSTCD,EMOHYY,EMCORP,EMPAY#
C+ FROM HRV6DTA/HRPEMP
C+ ORDER BY Case  When :F1Sort = 'Y' then EMEMP#
C+                When :F1Sort = 'N' then EMLNAM
C+                Else NULL
C+          End,    
C+          Case  When :F1Sort = 'N' then EMFNAM
C+                Else NULL   
C+          End
C/END-EXEC
