The following query grabs data that I need to pivot but Max and Sum don't play well in the same sentence so to speak. Stubborn Aggregates. I have tried various sub selects but the results come out incredibly wrong.

select hhicusn, hhiclsn,
(CASE HHICRDC WHEN 'DAM' THEN sum(hhiexsg) end) as DAM,
(CASE HHICRDC WHEN 'CON' THEN sum(hhiexsg) end) as CON,
(CASE HHICRDC WHEN 'MIS' THEN sum(hhiexsg) end) as MIS

from pwrdta.hhiorddp

where hhifspd in ( 1, 2, 3) and hhifsyr = 2017 and hhicrin = 'Y' and hhiclsn in ('  1', '  2', '  3', '  4', '  5', '  6', '  7', '  8', '  9', ' 10', ' 12', ' 13', ' 30', ' 31') and hhicrdc in ('DAM', 'CON', 'MIS')

group by hhicusn, hhiclsn, hhicrdc
order by hhicusn, hhiclsn

Could you please post few rows and the expected output. Try...Changes marked in bold.

select hhicusn, hhiclsn,
SUM(CASE HHICRDC WHEN 'DAM' THEN (hhiexsg) ELSE colName or you can provide hardcoded value also end) as DAM,
SUM(CASE HHICRDC WHEN 'CON' THEN (hhiexsg) ELSE colName or you can provide hardcoded value also end) as CON,
SUM(CASE HHICRDC WHEN 'MIS' THEN (hhiexsg) ELSE colName  or you can provide hardcoded value also end) as MIS

from pwrdta.hhiorddp

where hhifspd in ( 1, 2, 3) and hhifsyr = 2017 and hhicrin = 'Y' and hhiclsn in
('  1', '  2', '  3', '  4', '  5', '  6', '  7', '  8', '  9', ' 10', ' 12', ' 13', ' 30', ' 31')
and hhicrdc in ('DAM', 'CON', 'MIS')

group by hhicusn, hhiclsn, hhicrdc
order by hhicusn, hhiclsn

The code above results in the following:

hhicusn          hhiclsn          Dam          Con          Mis
00146             1                     -27.50
00146             1                                       -11.95
00146             1                                                         -15.99

The result I am looking for would be:

hhicusn          hhiclsn          Dam          Con          Mis
00146             1                     -27.50      -11.95       -15.99

I'm guessing I need another select along the lines of

SUM(CASE HHICRDC WHEN 'DAM' THEN (SELECT sum(hhiexsg) from ???

end) as DAM,

I have tried variations, but they keep coming out wrong.

Hi Jeff,

Yes you need another select like below..

SELECT hhicusn  ,        hhiclsn , MAX(Dam) Dam ,      MAX(Con)  Con         , MAX(Mis) Mis
FROM
(
select hhicusn, hhiclsn,
SUM(CASE HHICRDC WHEN 'DAM' THEN (hhiexsg) ELSE colName or you can provide hardcoded value also end) as DAM,
SUM(CASE HHICRDC WHEN 'CON' THEN (hhiexsg) ELSE colName or you can provide hardcoded value also end) as CON,
SUM(CASE HHICRDC WHEN 'MIS' THEN (hhiexsg) ELSE colName  or you can provide hardcoded value also end) as MIS

from pwrdta.hhiorddp

where hhifspd in ( 1, 2, 3) and hhifsyr = 2017 and hhicrin = 'Y' and hhiclsn in
('  1', '  2', '  3', '  4', '  5', '  6', '  7', '  8', '  9', ' 10', ' 12', ' 13', ' 30', ' 31')
and hhicrdc in ('DAM', 'CON', 'MIS')

group by hhicusn, hhiclsn, hhicrdc
)k GROUP BY hhicusn  ,        hhiclsn

Hope it helps !!
