使用ROW_NUMBER()查询：列名 'RowNumber' 无效。

原文:使用ROW_NUMBER()查询：列名 'RowNumber' 无效。

使用ROW_NUMBER()方法查询结果集；语句如下：

 

select ROW_NUMBER() OVER(ORDER BY dbo.OrderOutProduct.ID) AS RowNumber,

 dbo.Order.ID,Telephone,AddressCity,Province, from dbo.Order 

inner join dbo.Order2

on dbo.Order.ID=Order2ID

inner join dbo.Order3

on dbo.Order2.OrderID=dbo.Order3.Order3

where Service=1 and RowNumber=1

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

但是出现了错误：列名 'RowNumber' 无效。

查到网上给的解释是：在sql里这个叫做，热名称，刚定的不能立马使用！要包一层查询！

修改为：

select * from(

select ROW_NUMBER() OVER(ORDER BY dbo.OrderOutProduct.ID) AS RowNumber,

dbo.Order.ID,Telephone,AddressCity,Province, from dbo.Order 

inner join dbo.Order2

on dbo.Order.ID=Order2ID

inner join dbo.Order3

on dbo.Order2.OrderID=dbo.Order3.Order3

where Service=1 

)U where RowNumber=1

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
