Question

sql server 2005 我有一个存储过程，我用它将数据插入表中。某些数据需要来自执行存储在单独表中的查询的结果。

我一直遇到的主要问题是无法正确执行返回的查询。我已经尝试根据我读过的其他帖子在过去几天创建了几个函数，但是我继续使用exec，execute，sp_executesql等来解决sql错误。

我将粘贴几个可用于复制环境的脚本。我希望有人能够提供一个实际的代码示例，它将执行返回的查询以便在存储的proc插入函数中使用。

谢谢!!!

您可以查看this fiddle

存储过程的代码是：

CREATE PROCEDURE [dbo].[spInsertStuff]

@cli_id int

AS


DECLARE @SQL AS VARCHAR(MAX)
DECLARE @ADL_ID AS INT

DECLARE MyCURSOR
CURSOR FOR 
SELECT QUERY, ADL_ID FROM ASSESSMENT_DATALABEL_LIST

OPEN MyCURSOR   
FETCH NEXT FROM MyCURSOR INTO @SQL, @ADL_ID   

WHILE @@FETCH_STATUS = 0   
BEGIN   

        SET @SQL = REPLACE(@SQL,'@KeyFieldValue',@cli_id)
        DECLARE @Temp AS TABLE ([Value] [nvarchar](50))

        INSERT INTO @Temp
        EXEC (@SQL)

        INSERT INTO Item_Destination
        (ItemType, ItemCaption, ItemValue)
        SELECT
        ItemType, ItemCaption, (SELECT [Value] FROM @Temp)
        FROM Item_Source 
        WHERE Item_Source.adl_ID = @ADL_ID   

        DELETE FROM @Temp

        FETCH NEXT FROM MyCURSOR INTO @SQL, @ADL_ID   
END   

CLOSE MyCURSOR   
DEALLOCATE MyCURSOR

GO

使用sql存储过程插入从存储在表中的查询返回的数据
