Question

I have table like this, name: Table.dbo

Amount  Desc    Month   SM  code    ID
$32,323.00  Bla1    1   121 3   2424221
$4,242.00   Bla2    1   A1  3   2424221
$3,535.00   Bla3    1   A3  1   3230824

$24,224.00  Bla9    2   132 24  3434334

I wrote this query :

select 
[SM],
   count(*) as TotalCntOfSM,
   sum(case when [code] between 4 and 27 then 1 else 0 end) as TotalCntOfSM_R,
   sum(case when [code] in (1,2,3) then 1 else 0 end) as TotalCntOfSM_B,
   sum(case when [code] in (1) then 1 else 0 end) as TotalCntofSM_B1,
   sum(case when [code] in (2) then 1 else 0 end) as TotalCntofSM_B2,
   sum(case when [code] in (3) then 1 else 0 end) as TotalCntofSM_B3,
   sum([Amount]) As TotalAmount
   ****[How can I sum the Amount for the SM if the code is between 4 and 27?** For example]** 
from [Table]
group by [SM]
order by TotalCntOfSM desc

How can I sum the Amount for the SM if the code is between 4 and 27 or the code is in (1,2,3) only (For example).

Thank you very much!

Answer 1

Exactly like qxg said - Replace

****[How can I sum the Amount for the SM if the code is between 4 and 27?** For example]** `

with

sum(case when [code] between 4 and 27 then [Amount] else 0 end) as SMAmount

If you want to total up amount for code between 4 and 27 or for codes 1,2,3

sum(case when [code] between 1 and 27 then [Amount] else 0 end) as SMAmount
You can write the above also as
sum(case when [code] between 4 and 27 OR [code] in (1,2,3) then [Amount] else 0 end) as SMAmount
