Question

以下是我的示例存储过程。当我通过传递DATE执行存储过程时，它显示以下错误。

无效的对象名称'TEMPP'

- 存储过程

ALTER  PROCEDURE [dbo].[mystoredprocedure]
@abc DATETIME  //coming fron front-end
AS   
BEGIN  
SET NOCOUNT ON;

WITH TEMPP AS
 (  
SELECT DISTINCT(ID), NAME  
FROM EMPLOYEE WHERE EMPDATE > @abc 
 )  
    select DP.NAME INTO xy  from DEPARTMENT DP,TEMPP TE  
    where DP.ID=TE.ID  ;

SELECT * FROM xy;
DROP xy;
END

哪里出错？

Answer 1

来自网上书籍：递归成员的CTE_query_definition中不允许使用以下项：

SELECT DISTINCT [...]

你可以试试这个：

ALTER  PROCEDURE [dbo].[mystoredprocedure]
@abc DATETIME  //coming fron front-end
AS   
BEGIN  
SET NOCOUNT ON;

    select DP.NAME from DEPARTMENT DP
    inner join
    (
        SELECT DISTINCT(ID), NAME  
        FROM EMPLOYEE WHERE EMPDATE > @abc
    )TE ON DP.ID=TE.ID;

END

Answer 2

如果您的ID是您的主键，则它已经是DISTINCT，这意味着如果@ibram answer是导致错误的原因，您可以将其删除。我认为xy意味着是一个临时表，并且看不到任何用途。

ALTER  PROCEDURE [dbo].[mystoredprocedure]
   @abc DATETIME  //coming fron front-end
AS   
BEGIN  

SET NOCOUNT ON;

WITH TEMPP AS
(  
  SELECT ID, NAME  
  FROM EMPLOYEE WHERE EMPDATE > @abc 
)  
SELECT DP.NAME
FROM DEPARTMENT DP 
JOIN TEMPP TE
  ON DP.ID=TE.ID  ;

END

如果您稍后尝试在过程中引用CTE，通常会看到此错误。它仅对其定义后的声明有效。

ALTER PROCEDURE [dbo].[mystoredprocedure] @abc DATETIME
AS
  BEGIN
      SET NOCOUNT ON;

      WITH TEMPP
           AS (SELECT DISTINCT ( name ),
                               number
               from   master..spt_values)
      select number
      INTO   xy
      from   TEMPP;

      SELECT *
      FROM   xy;

      DROP table xy;

    SELECT * FROM TEMPP /*Not Allowed: Throws this error*/
  END
