Question

SQL Server 2008

Hi

I have an issue where i have two of the same accounts which i would like to merge together, the list looks like below:

AcctID  AcctType  AcctSubType  Curr  TransType  Amount
1        CCY       SET          EUR   Opening    1000
1        CCY       SET          EUR   BUY        -100
1        CCY       SET          EUR   SEL        100
1        CCY       SET          EUR   Closing    1000
2        CCY       SET          EUR   Opening    2000
2        CCY       SET          EUR   SEL        100
2        CCY       SET          EUR   Closing    2100
3        CCY       INC          EUR   Opening    1000
3        CCY       INC          EUR   SEL        200
3        CCY       INC          EUR   BUY        -100
3        CCY       INC          EUR   Closing    1100

So basically i would like to merge it so it looks like this:

AcctID AcctType  AcctSubType  Curr  TransType  Amount
1      CCY       SET          EUR   Opening    3000
1      CCY       SET          EUR   BUY        -100
1      CCY       SET          EUR   SEL        100
2      CCY       SET          EUR   SEL        100
1      CCY       SET          EUR   Closing    3100
3      CCY       INC          EUR   Opening    1000
3      CCY       INC          EUR   SEL        200
3      CCY       INC          EUR   BUY        -100
3      CCY       INC          EUR   Closing    1100

However i can’t think of the best way to code this in SQL in my stored proc. I can only really think of a merge or a union, but i only want it to merge where there are two capital accounts, a capital account is signified by the ‘CCY’ AcctType and AcctSubType ‘SET’.

A point in the right direction would be much appreciated.

Thanks

How about this:

;with test (AcctID, AcctType, AcctSubType, Curr, TransType, Amount)
as
(
select 1, 'CCY', 'SET', 'EUR', 'Opening', 1000
union all
select 1, 'CCY', 'SET', 'EUR', 'BUY', -100
union all
select 1, 'CCY', 'SET', 'EUR', 'SEL', 100
union all
select 1, 'CCY', 'SET', 'EUR', 'Closing', 1000
union all
select 2, 'CCY', 'SET', 'EUR', 'Opening', 2000
union all
select 2, 'CCY', 'SET', 'EUR', 'SEL', 100
union all
select 2, 'CCY', 'SET', 'EUR', 'Closing', 2100
union all
select 3, 'CCY', 'INC', 'EUR', 'Opening', 1000
union all
select 3, 'CCY', 'INC', 'EUR', 'SEL', 200
union all
select 3, 'CCY', 'INC', 'EUR', 'BUY', -100
union all
select 3, 'CCY', 'INC', 'EUR', 'Closing', 1100
union all
select 4, 'CCY', 'SET', 'SEK', 'Opening', 2000
union all
select 4, 'CCY', 'SET', 'SEK', 'SEL', 100
union all
select 4, 'CCY', 'SET', 'SEK', 'Closing', 2100
)
, needed as
(
select  *
from    test
where   AcctType = 'CCY'
    and AcctSubType = 'SET'
    and TransType in ('Opening','Closing')
)
select  min(AcctID) as AcctID
        ,AcctType
        ,AcctSubType
        ,Curr
        ,TransType
        ,sum(Amount) as Amount
from    needed
group by
        AcctType
        ,AcctSubType
        ,Curr
        ,TransType
union all
(   
    select  *
    from    test
    except
    select  * 
    from    needed
)

EDIT: Updated to support multiple currencys.

The only change is to wrap the final SELECT - EXCEPT in parantheses.
