Question

我有一个动态数据透视查询，我想转向businessaccountnumber，我知道它存在于transaction_table中，但它一直返回“无效的列名'bizi'。” - 对于第1行。

DECLARE @Output nvarchar(max) = N''
DECLARE @PivotList varchar(max)


SELECT
  @PivotList = COALESCE(@PivotList + ', ', N'') + N'[' + bizid + N']'

FROM (SELECT DISTINCT
  BusinessAccountNumber [bizid]
FROM transaction_table
WHERE postingdate BETWEEN '1/01/2015' AND '2/01/2015'
) AS CustProds;

SET @Output = 'SELECT [bizName],[bizi]
    , ' + @PivotList + '
FROM  ( select businessname as [bizName],businessaccountnumber as [bizi],
        sum((Transactionamount*(-1))) as [Transactionamount] 
        FROM transaction_table
        WHERE postingdate between ''1/01/2015'' and ''2/01/2015''
        GROUP BY businessaccountnumber,businessname) as P
PIVOT ( SUM(Transactionamount) FOR P.bizi IN (' + @PivotList + ') ) AS PVT'

EXEC sp_executesql @Output;

编辑：感谢Backs指出我的错误，但现在我遇到了一个新错误。

我正在寻找的输出是：

Date      | bizid12| bizid13| bizid14...
01/01/2015|  $1    | $3     | $56
01/02/2015| $12    | $34    | $3
.....


DECLARE @Output nvarchar(max) = N''
DECLARE @PivotList varchar(max)


SELECT
  @PivotList = COALESCE(@PivotList + ', ', N'') + N'[' + bizid + N']'

FROM (SELECT DISTINCT
  BusinessAccountNumber [bizid]
FROM transaction_table
WHERE postingdate BETWEEN '1/01/2015' AND '2/01/2015'
) AS CustProds;

SET @Output = 'SELECT [sp_date]
    , ' + @PivotList + '
FROM  ( select Convert(varchar,postingdate,101) as [sp_date] 
        ,businessaccountnumber as [bizi],
        sum((Transactionamount*(-1))) as [Transactionamount] 
        FROM transaction_table
        WHERE postingdate between ''1/01/2015'' and ''2/01/2015''
        GROUP BY businessaccountnumber) as P
PIVOT ( SUM(Transactionamount) FOR P.bizi IN (' + @PivotList + ') ) AS PVT'

EXEC sp_executesql @Output;

现在出现错误：

Msg 8180，Level 16，State 1，Line 1
  声明无法准备。

Msg 102，Level 15，State 1，Line 1
  'Qry12090'附近的语法不正确。

Msg 1056，Level 15，State 1，Line 1
  选择列表中的元素数量超过允许的最大数量4096个元素。

您无法在PIVOT SELECT [bizName],[bizi]中使用它在查询FOR P.bizi IN中选择bizi。从select语句中删除[bizi]
