爲什麼@Table不適合我？

Question

有人可以告訴爲什麼這個查詢不起作用嗎？

DECLARE @unwantedRows TABLE 
( 
    ProductId INT, 
    ProductName VARCHAR(50), 
    Description VARCHAR(50), 
    Category VARCHAR(50), 
    Repetitions VARCHAR(50) 

); 

Select * 
INTO @unwantedRows From 
(
Select a.*,Row_Number() Over(Partition By ProductId Order By ProductId) As [Repetitons] from tblProduct a 
) As A 

Where A.Repetitons > 1 

錯誤我得到的是

`消息102，級別15，狀態1，行12 附近有語法錯誤@unwantedRows「。 Msg 156，Level 15，State 1，Line 15 關鍵字'As'附近的語法不正確。

編輯：

現在，它與Repetitions，並提供： -

INSERT 
INTO @unwantedRows 
Select a.*,Row_Number() Over(Partition By ProductId Order By ProductId) As [Repetitons] from tblProduct a 
Where a.Repetitons > 1 

`

Invalid column name 'Repetitons'.

一個錯誤，我發現它是不選擇到其選擇..插入聲明

以下查詢沒有錯誤做工精細上述查詢即語法錯誤

DECLARE @unwantedRows TABLE 
( 
    ProductId INT, 
    ProductName VARCHAR(50), 
    Description VARCHAR(50), 
    Category VARCHAR(50), 
    Repetitions VARCHAR(50) 

); 

insert INTO @unwantedRows 
Select a.*,Row_Number() Over(Partition By ProductId Order By ProductId) As [Repetitons] from tblProduct 
Where A.Repetitons > 1 

insetead你也可以試試這個

insert INTO @unwantedRows 
select * from (
Select a.*,Row_Number() Over(Partition By ProductId Order By ProductId) As [Repetitons] from tblProduct) d 
Where d.Repetitons > 1 

Answer 2

因爲select into創建一個表，你想insert into @unwantedRows select * from ...

---

編輯

，然後你不允許在Where子句中使用窗口函數（如分區）。如果你必須這樣做，換你選擇到另一個選擇：

select * from (select * from ...) as a where a.Partition > 1 

Answer 3

您需要刪除SELECT INTO，你需要指定列。

INSERT @unwantedRows 
SELECT a.ProductID, a.ProductName, a.Description, a.Category, a.Repetitions 
FROM (
    Select *, Row_Number() Over (Partition By ProductId Order By ProductId) As [Repetitons] 
    from tblProduct) As A 
Where A.Repetitons > 1; 

Answer 4

insert into @unwantedRows 
Select * from 
(
Select a.*,Row_Number() Over(Partition By ProductId Order By ProductId) As [Repetitons] from tblProduct a 
) As A 
Where A.Repetitons > 1
