为什么@Table不适合我？

Question

有人可以告诉为什么这个查询不起作用吗？

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 

错误我得到的是

`消息102，级别15，状态1，行12 附近有语法错误@unwantedRows“。 Msg 156，Level 15，State 1，Line 15 关键字'As'附近的语法不正确。

编辑：

现在，它与Repetitions，并提供： -

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'.

一个错误，我发现它是不选择到其选择..插入声明

以下查询没有错误做工精细上述查询即语法错误

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你也可以试试这个

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

因为select into创建一个表，你想insert into @unwantedRows select * from ...

，然后你不允许在Where子句中使用窗口函数（如分区）。如果你必须这样做，换你选择到另一个选择：

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

Answer 3

您需要删除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
