Question

I am trying to build this type of query in SQLServer for my report but for branches.

Branch_Master

Branch_ID
Branch_Name

CheckList_Master

CheckList_ID
CheckList_Name

CheckList_Detail

CheckList_ID
Branch_ID
Chk_Value
ResponseDate

Now I want to pass only the month and year and it should do something like the following. Note: I have taken this query from oracle forum for the requirement of MONTHS but i want BRANCHES. Also note for example if i have 12 branches in detail table but 28 branches in master still i need to show 28 branches in query and show 0 value if no data of relavent branch in detail table.

select
c_name,
sum(decode(mon, 'Jan', pono, 0)) jan,
sum(decode(mon, 'Feb', pono, 0)) feb,
.....
.....
sum(decode(mon, 'Nov', pono, 0)) nov,
sum(decode(mon, 'Dec', pono, 0)) dec,
sum(decode(mon, 'Mon_Total', pono, 0)) mtotal
from (
select decode(grouping(c_name), 1, 'Total', c_name) c_name,
decode(grouping(month), 0, month, 'Mon_Total') mon, sum(po_no) pono
from t
group by cube(c_name, month)
)
group by c_name

And the result may look like:

C_NAME BR1 BR2 BR3 BR4 BR5 BR6 BR7 BR8 BR9 BR10 BR11 BR12 TOTAL_OF_ROW
------------------------------ ---------- ---------- ---------- ----------    
----------    ---------- ---------- ---------- ---------- ---------- ---------- 
CHKLST1 1 2 3 4 5 6 7 8 9 10 11 12 78
CHKLST2 20 30 40 50 60 70 80 90 100 110 120 780

Use PIVOT.

SELECT *
FROM
(
    SELECT c.CheckList_Name,
        b.BranchName,
        COUNT(*) ItemCount
    FROM dbo.CheckList_Detail cd
    JOIN dbo.CheckList_Master c
        ON c.CheckList_ID = cd.CheckList_ID
    JOIN dbo.Branch_Master b
        ON b.Branch_ID = cd.Branch_ID
) a
PIVOT
(
    MIN(ItemCount) FOR BranchName IN
    (
        [BR1], [BR2], [BR3], [BR4], [BR5], [BR6],
        [BR7], [BR8], [BR9], [BR10], [BR11], [BR12]
    )
) b
