SQLServer 2008 新增T-SQL 简写语法

1.定义变量时可以直接赋值
DECLARE @Id int = 5
2.Insert 语句可以一次插入多行数据
INSERT INTO StateList VALUES(@Id, 'WA'), (@Id + 1, 'FL'), (@Id + 2, 'NY')
3.支持+=操作符
SET StateId += 1
完整示例如下：

复制代码代码如下:

	
	CREATE TABLE StateList(StateId int, StateName char(2)) 

	GO 

	-- Declare variable and assign a value in a single statement 

	DECLARE @Id int = 5 

	-- Insert multiple rows in a single statement with IDs 5, 6, and 7 

	INSERT INTO StateList VALUES(@Id, 'WA'), (@Id + 1, 'FL'), (@Id + 2, 'NY') 

	-- Use compound assignment operator to increment ID values to 6, 7, and 8 

	UPDATE StateList 

	SET StateId += 1 

	-- View the results 

	SELECT * FROM StateList

结果集为：

StateId StateName
------- ---------
6 WA
7 FL
8 NY
