Thanks to all who responded.
I have taken the solution provided by Birgitta
I had never used CTEs, so I'm excited to use this method.
Thanks
Mike

Subject: AW: Problems with Group by and case in sql
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
