tsql - TSQL PIVOT 抛出多部分标识符无法绑定

我在 SQL Server 2005 中使用以下语法创建了一个存储过程：

当我尝试更改存储过程时，我收到以下信息：

消息 4104，级别 16，状态 1，过程 sp_sc_ConRptsSurgery，第 16 行
无法绑定多部分标识符“EncounterProc.Encounter Number”。

必须对上述语法做什么才能更正上述错误？

更新：我将左外连接更改为以下内容：

Left Outer JOIN ( SELECT *
FROM (SELECT [Encounter Number]
,[Procedure Code (Enctr)]
,Row_Number() OVER 
( Partition By [Encounter Number] 
Order By [EncounterNumber], [Procedure Code (Enctr)] ) AS RowNumber
FROM EncounterProc) o
PIVOT ( MAX([Procedure Code (Enctr)] ) for RowNumber IN ( [1], [2], [3], [4], [5], [6], [7], [8], [9],

,[41], [42], [43], [44], [45], [46], [47], [48], [49]) ) t ) pr
on Encounter.EncounterNumber = pr.[Encounter Number]

更新 2：这是 EncounterProc 表的结构：

CREATE TABLE [dbo].[EncounterProc](
[COMPANY CODE] [varchar](5) NULL,
[ENCOUNTER NUMBER] [varchar](20) NOT NULL,
[PROCEDURE CODE (ENCTR)] [varchar](15) NOT NULL,

       )WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,ALLOW_ROW_LOCKS    
       = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
       ) ON [PRIMARY]

不幸的是，错误仍然存在，包括：

Msg 207, Level 16, State 1, Procedure sp_sc_ConRptsSurgery, Line 95
Invalid column name 'EncounterNumber'.
Msg 207, Level 16, State 1, Procedure sp_sc_ConRptsSurgery, Line 103

Invalid column name 'Date of Service'.
Msg 207, Level 16, State 1, Procedure sp_sc_ConRptsSurgery, Line 112
Invalid column name 'Procedure Code (ENCTR)'.

为什么这些列名被视为无效？

更新 3：不知道为什么我的问题被否决了？通过错误消息解析后，我将存储过程重组如下：

存储过程现在运行无错误。但是，我看到相同的遭遇号重复了许多行，因为它有程序。如果有 7 个过程，则存储过程会为此遇到返回 7 行。

我将如何修改上面的更新代码以确保存储过程每次遇到只返回一行？

I believe the error is at the end of your PIVOT:

) pr
on Encounter.EncounterNumber = EncounterProc.[Encounter Number]
                                  ^-- this should be pr

So the code should be:

) pr
on Encounter.EncounterNumber = pr.[Encounter Number]

Edit, based on your additional errors, it appears that you are not including the [DATE OF SERVICE] in your subquery. Also it doesn't make sense that you have a filter on the outside WHERE clause using the [Procedure Code (ENCTR)] because you are using that column in your max() on the PIVOT. Based on those guesses your code seems like it should be:
