SQLServer 2008 新增T-SQL 简写语法

答案：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 

(3 row(s) affected)
