SQL2005支持的两条新语法

1. OUTPUT ... INTO

用于将一条记录从表一移动到表二时非常好用，常见于备份记录的应用

例一：

DELETE [TableUseing] 

OUTPUT Deleted.* 

INTO [TableBak]

.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; }例二：（用于移动时修改某字段的值）

DELETE [TableUseing] 

OUTPUT Deleted.Field1, Deleted.Field2, GETDATE() 

INTO [TableBak]

.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; }

2.表变量

用于存储临时的查询结果

DECLARE @tmp TABLE (ID INT, CITY NVARCHAR(50))

INSERT INTO @tmp 

SELECT MIN(ID), CITY  

FROM [TableTest] WITH(NOCLOCK) 

GROUP BY CITY
