【问题描述】：

我无法找到与帐户相关的报告我需要在一行中获得信用卡账户和借记账户..with amount

我的桌子是这样的

Id  VoucherId   AccountId   Amount  AccountName IsDebit
1   1           26          100     Sales       0
2   1           10          100     Cash        1
3   2           26          200     Sales       0
4   2           10          200     Cash        1
5   3           10          150     Cash        0
6   3           20          150     Expense A   1
7   4           10          240     Cash        0
8   4           21          240     Expense B   1

我需要得到这样的结果 VoucherId DebitName DebitID CreditName CreditID Amount 1 Cash 10 Sales 26 100 2 Cash 10 Sales 26 200 3 Expense a 10 Cash 26 150 4 Expense b 10 Cash 26 240 我试过这个

select vc.Id,
am.Name,vc.AccountName,vd.[Description],
    case when vd.isdebit=1 then vd.amount else 0 end  as C6,
    case when vd.isdebit=1 then vd.AccountId else 0 end as A,
    case when vd.isdebit=0 then vd.amount else 0 end as C7,
    case when vd.isdebit=0 then vd.AccountId else 0 end as B
    from VoucherDetails vd 
    inner join Voucher Vc on vc.Id=vd.VoucherId and vc.IsDeleted=0
    inner join AccountsMaster Am on am.Id=vd.AccountId

和许多其他查询，但没有得到上述结果

请帮助..提前感谢

【解决方案1】：

如果您进行复式输入，这将起作用。也就是说，每个借方条目也应该有一个贷方条目。

select DrVoucherId as VoucherId,DebitName,DebitId,CreditName,CreditId,Amount from (
select VoucherId as DrVoucherId,AccountName as DebitName ,AccountId as DebitId from VoucherDetails where IsDebit=1
) a
left join
(select VoucherId as CrVoucherId,AccountName as CreditName ,AccountId as CreditId,Amount from VoucherDetails where IsDebit=0) b on  a.DrVoucherId=b.CrVoucherId

像这样？：

select VoucherId,
  max(case when IsDebit = 1 then AccountID end) DebitID,
  max(case when IsDebit = 1 then am.Name end) DebitName,
  max(case when IsDebit = 0 then AccountID end) CreditID,
  max(case when IsDebit = 0 then am.Name end) CreditName,
  Amount
from VoucherDetails vd
  join AccountsMaster am on am.Id = AccountID
group by VoucherId, Amount
order by VoucherId

你需要聚合：

select vc.Id, 
       sum(case when vd.isdebit = 1 then vd.amount else 0 end)  as C6,
       sum(case when vd.isdebit = 1 then vd.AccountId else 0 end) as A,
       sum(case when vd.isdebit = 0 then vd.amount else 0 end) as C7,
       sum(case when vd.isdebit = 0 then vd.AccountId else 0 end) as B
from VoucherDetails vd join
     Voucher Vc 
     on vc.Id = vd.VoucherId and vc.IsDeleted = 0 join
     AccountsMaster Am
     on am.Id = vd.AccountId
group by vc.Id

实际上我需要将两行合并为1，其中凭证ID相同，您的查询为每个凭证ID返回2行，感谢您的快速回复
@丽莎。 . .然后从 select 和 group by 中删除所有未聚合的列，凭证 ID 除外。
