AW: Problems with Group by and case in sql

["Birgitta Hauser" <Hauser@xxxxxxxxxxxxxxx>]

I'd use at least 2 Common table expressions:

With a as (Select distinct PRDPT  
              from PROVRDPT00
              Where PRNAME = 'BRANDTNS'),
     b as (Select PLBEMP, PLBGG1, PLBHRS, 
                  Case When PLBPTP = 'CO' Then 'CALLOUT'
                       Else 'OVERTIME' 
                       End FldCase
             From PRLBH
             Where     PLBEDT = 20100228 
                   and PLBPTP in ('CO','OH', '6D','7D','OG'))
Select EEUN, EEDPT, PLBEMP, EENAM, PLBBG1, FldCase, Sum(PLBHRS)
  From b Join EEMP on PLBEMP = EENO 
         Join a    on PRDEPT = EEDPT
  Where  EETDT = 0
  Group By EEUN, EEDPT, PLBEMP, EENAM, PLBBG1, FldCase
  Order By ... whatever sequence you need
                  

Mit freundlichen Grüßen / Best regards

Betreff: Problems with Group by and case in sql

I have a SQL I'm trying to write. My first attempt is trying to use a
case statement in a GROUP BY clause.  

SELECT eeun, eedpt, plbemp, eenam, plbbg1, plbptp, sum(plbhrs)   
FROM PRLBH, EEMP
WHERE PLBEMP = EEENO  and PLBPTP in('CO','OH', '6D','7D','OG')

 and EETDT = 0 and   EEDPT  in (select PRDPT from PROVRDPT00 where
PRNAME = 'BRANDTNS')

and  PLBEDT = 20100228

 GROUP BY PLBEMP,EENAM,PLBBG1,EEUN, EEDPT ,         
case  PLBPTP when 'CO' then 'CALLOUT'

             Else 'OT'                                              
             End       

I get errors telling me PLBPTP or expression in select list not valid

If I remove the case on the group by I get results, but not what I would
like ideally. 

In researching this, I came across a CTE example that I worked like this


with x (a,b,c,d,e,f) as (SELECT eeun, eedpt, plbemp, eenam, plbbg1,
sum(plbhrs) case plbptp when 'CO' then 'CALLOUT'                   
                         when 'OT' then 'OVERTIME'                 
                         when '6D' then 'OVERTIME'                 
                         when '7D' then 'OVERTIME'                 
                         when 'OG' then 'OVERTIME'                 
                         else 'OTHERS'                             
                         end                                       
 from PRLBH, EEMP                                                  
 WHERE PLBEMP = EEENO                                              
and PLBPTP in('CO','OH', '6D','7D','OG') and EETDT = 0 and EEDPT   
in (select PRDPT from PROVRDPT00 where PRNAME = 'BRANDTNS') and    
PLBEDT = 20100228)                                                 
select a,b,c,d,e,f  from x group by c,d,e,a,b,f


On this one I get token  PLBPTP not valid on my case statement. 

This one will work if I remove the sum(plbhrs), but I need it in my
final results.  

Any idea what I'm doing wrong on either one of these.          

Thanks for any help 

Mike
