Question

您能帮我this吗？

我想将金额列分为借方和贷方两列，并按帐户ID将借方和贷方总和分组

这是我的桌子：

ID | GeneralLedgerHeaderId | AccountId | DrCr | Ammount
1  |           1           |     2     |   1  | 200.000
2  |           1           |     4     |   1  | 200.000
3  |           1           |     5     |   2  | 428.000
4  |           1           |     8     |   1  | 28.000
5  |           2           |     5     |   1  | 428.000

Answer 1

假设DrCr=1表示借方，DrCr=2表示贷方，则可以使用两个case表达式：

SELECT   AccountId,
         SUM(CASE DrCr WHEN 1 THEN Amount END) AS sum_debit,
         SUM(CASE DrCr WHEN 2 THEN Amount END) AS sum_credit
FROM     mytable
GROUP BY AccountId

Answer 2

您想要以下东西吗？您可以将SUM（）函数与Partition By子句一起使用，以便以Partition By子句中定义的自定义分类的方式获得Count()之类的聚合

select
    Id,
    GeneralLedgerHeaderId,
    AccountId,
    case when DrCr = 1 then Amount end as Debit,
    case when DrCr = 2 then Amount end as Credit,
    Summed = SUM(case when DrCr = 1 then (-1 * Amount) else Amount end) over (partition by AccountId)
from Transactions

将评论编辑到此帖子后的第二次查询

SELECT
    GL.AccountId,
    CA.Code,
    CA.AccountName, 
    SUM(CASE GL.DrCr WHEN 1 THEN Amount END) AS sum_debit, 
    SUM(CASE GL.DrCr WHEN 2 THEN Amount END) AS sum_credit,
    SUM(CASE GL.DrCr WHEN 1 THEN Amount ELSE (-1 * Amount) END) AS sum_total
FROM GeneralLedgerLine GL 
Join COA_Client CC 
    on GL.AccountId = CC.AccountId 
join ChartOfAccount CA 
    on CC.COA_Id = CA.COA_Id 
GROUP BY
    GL.AccountId, CA.Code, CA.AccountName

Answer 3

使用汇总时的用例，这里我假设DrCr = 1借项而2表示贷项

select accountid, sum(case when DrCr=1 then Amount end) as dr,
sum( case when DrCr=2 then Amount end) as cr from your_table
group by accountid
