在同一存储过程中使用3个更新？``商场错误''

如何解决在同一存储过程中使用3个更新？``商场错误''

您启动的SP;WITH ratingLines ...连接到第一个UPDATE语句，而不连接其他语句。此构造创建一个CTE，该CTE仅对它后面的第一条语句可见。可以在TN中找到有关WITH common_table_expression（Transact-SQL）的更多说明。特别是摘录自“备注”的摘录突出了这一点：

CTE之后必须是引用某些或所有CTE列的单个SELECT，INSERT，UPDATE，MERGE或DELETE语句。

若要使该表为您SP中的所有语句所知，请为它创建一个表变量或一个临时表ratingLines。

使用临时表的大纲如下：

Select   RDA.[CTS]        AS [CTS]
              ,RDA.[B_KEY]        AS [B_KEY]
              ,RDA.[H_KEY]        AS [H_KEY]
              ,RDA.[RT_ID]        AS [RT_ID]
              ,RDA.[RT_AVGrating] AS [RT_AVGrating]
              ,RDDA.[RTD_COMMENT] AS [RTD_COMMENT]
INTO #ratingLines -- Create #ratingLines as temporary table
From  [DynNavHRS].[HRSDB].[HTL_rating_ALL_DA]        RDA
Join  [DynNavHRS].[HRSDB].[HTL_rating_DETAIL_ALL_DA] RDDA
ON    RDA.RT_ID =RDDA.RT_ID
AND   RDDA.[RTD_COMMENT] <> ''
AND   RDA.[B_KEY]='19214642';

-- Throughout the rest of the SP, use #ratingLines as your ratings table; eg:
...
INNER JOIN #ratingLines   RL1
...

-- At the end of the SP, drop the temporary table
DROP TABLE #ratingLines;

解决方法

我有以下SP，它具有3条更新语句。每个执行此SP的程序，我都会收到一个错误“消息208，级别16，状态1，过程sp_Rating_Comments，第41行无效的对象名称’RatingLines’。”。此错误位于第二条更新语句中。当我隐藏第二条和第三条更新语句时，我的代码工作正常。知道如何将这3个Update语句一起使用。

Alter PROCEDURE [HRSDB].[sp_Rating_Comments]

-- @BookingNr varchar(25)

--,@Company varchar(30)

AS

  SET NOCOUNT ON;

     ;WITH RatingLines AS   -- Get the important columns from both HRSDB tables

        From  [DynNavHRS].[HRSDB].[HTL_RATING_ALL_DA]        RDA

        Join  [DynNavHRS].[HRSDB].[HTL_RATING_DETAIL_ALL_DA] RDDA
