【问题描述】：

我需要像运行余额或总计一样运行 VoucherNo 连接。如图所示，将前一个 VoucherNo 连接到当前 VoucherNo 行明智

查询是：

select 
v.VoucherDate,v.VoucherNo,v.VoucherType,v.Narration,SUM(v.Debit) Debit , SUM(v.Credit) Credit,dbo.GetBalance(v.CompanyProfileId,v.AccountCode,v.VoucherDate ,SUM(v.Debit), SUM(v.Credit)) Balance
from AcVoucher v
where v.VoucherDate Between '2016-03-24' and '2016-03-30' and v.CompanyProfileId = 2 and v.AccountCode = '05010001'
group by v.VoucherNo,v.VoucherDate,v.VoucherType,v.Narration,v.CompanyProfileId,v.AccountCode

架构：

    GO
/****** Object:  Table [dbo].[AcVoucher]    Script Date: 03/30/2016 3:47:02 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[AcVoucher](
    [Id] [bigint] IDENTITY(1,1) NOT NULL,
    [CompanyProfileId] [int] NOT NULL,
    [AccountCode] [nvarchar](50) NOT NULL,
    [VoucherNo] [bigint] NOT NULL,
    [VoucherType] [nvarchar](5) NOT NULL,
    [VoucherDate] [datetime] NOT NULL,
    [Narration] [nvarchar](500) NULL,
    [Debit] [float] NOT NULL,
    [Credit] [float] NOT NULL,
    [TaxPercentage] [float] NULL,
    [DiscountPercentage] [float] NULL,
    [CreatedBy] [int] NULL,
    [CreatedDate] [datetime] NULL,
 CONSTRAINT [PK_ACVoucher_1] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

没有previous 凭证号，除非您有指定订购的列。而且，不清楚该列是什么。
您的查询有什么问题？你有错误吗？
Calculate running total / running balance的可能重复

【解决方案1】：

您可以使用与 SQL Server 中的字符串连接基本相同的逻辑来执行此操作。唯一的区别是where 子句。

一个关键问题是连接的顺序。这在问题中并不明显，因此我在查询中添加了一个minid，它用于（以相反的顺序）选择要组合在一起的 id：

with v as (
      select v.VoucherDate, v.VoucherNo, v.VoucherType, v.Narration,
             SUM(v.Debit) as Debit , SUM(v.Credit) as Credit, 
             dbo.GetBalance(v.CompanyProfileId, v.AccountCode, v.VoucherDate,
                            SUM(v.Debit), SUM(v.Credit)
                           ) as Balance,
             min(id) as minid
      from AcVoucher v
      where v.VoucherDate Between '2016-03-24' and '2016-03-30' and
            v.CompanyProfileId = 2 and v.AccountCode = '05010001'
      group by v.VoucherNo, v.VoucherDate, v.VoucherType,v.Narration, v.CompanyProfileId, v.AccountCode
     )
select v.*,
       stuff((select ',' + cast(v2.VoucherNo as varchar(8000))
              from v v2
              where v2.minid >= v.minid
              for xml path ('')
             ), 1, 1, '') as RunningConcat
from v;
