SQL Server查询隐藏重复行列数据。不想删除重复的行。有条件地将数据显示为空白。
何时,我运行此SQL查询:
select
[Vch No.], [Vch Type], [Vch Ref],
[Date], [Party Name], [Sales Ledger],
[Amt], [GST Ledger], [TaxAmount], [Total]
from
[AccountData]
我收到了这个输出:
但是,我需要这种格式的输出:
在第二个打印屏幕中,我不显示[Vch Ref],[Date],[Party Name],[Sales Ledger],[Amt]和Total的值。
答案 0 :(得分:2)
这看起来像是一个疯狂的解决方案,但您可以使用窗口函数ROW_NUMBER()
并使用CASE
表达式来检查行号是否大于1,类似于:
select
[Vch No.],
[Vch Type],
case when rn > 1 then '' else [Vch Ref] end as [Vch Ref],
case when rn > 1 then '' else [Date] end as [Date],
case when rn > 1 then '' else [Party Name] end as [Party Name],
case when rn > 1 then '' else [Sales Ledger] end as [Sales Ledger],
case when rn > 1 then '' else [Amt] end as [Amt],
[GST Ledger],
[TaxAmount],
case when rn > 1 then '' else [Total] end as [Total]
from (
select
[Vch No.],
[Vch Type],
[Vch Ref],
[Date],
[Party Name],
[Sales Ledger],
[Amt],
[GST Ledger],
[TaxAmount],
[Total],
row_number() over (partition by [Vch No.],[Vch Type],[Vch Ref],[Date],[Party Name],[Sales Ledger],[Amt],[GST Ledger],[TaxAmount],[Total] order by [Vch No.]) rn
from [AccountData]
)x
查看数据类型,如果Amt
为INT,则应将其转换为字符串,如果要获取空值。
