Question

我希望每天执行一次存储过程，该过程将首先删除指定表中的数据，然后将新数据插入其中。

我的存储过程大致如下

ALTER PROCEDURE  [dbo].[SP_Name]

 AS BEGIN

 WITH  CTE_Name as 

   (   select
        Title,
        First_Name,
        Surname

         From table

   ) 

   DELETE [dbo].[NEW_TABLE]
   INSERT INTO [dbo].[NEW_TABLE]

   Select * from CTE_NAME

    END

执行查询时，我得到错误的无效对象名称'CTE_NAME'

我尝试删除'DELETE [dbo]。[NEW_TABLE]'行，执行此操作后，存储过程便会运行并将数据插入表中。

我正在使用SQl Management Studio 2012

您可以尝试以下代码：

ALTER PROCEDURE [dbo].[SP_Name] AS
BEGIN
    DECLARE @helperTbl TABLE (Title varchar(100), First_Name varchar(100), Surname varchar(100))
    INSERT INTO @helperTbl
    SELECT Title,
           First_Name,
           Surname
    FROM [table]

    DELETE FROM [dbo].[NEW_TABLE]
    INSERT INTO [dbo].[NEW_TABLE]
    SELECT * FROM @helperTbl
END

Answer 2

我认为您需要通过在其前面添加分号来分隔您的With

下面的代码应该可以工作

DECLARE @TABLE TABLE (
 id VARCHAR(100)
)
DELETE FROM @TABLE
;WITH  CTE_Name AS
(   
    SELECT id FROM OtherTable
)    
INSERT INTO @TABLE 
SELECT id FROM CTE_Name

删除并插入
