SQLServer 2008 新增T-SQL 简写语法

　　本文标签：SQLServer,T-SQL

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)
