我们今天主要和大家一起分享的是SQL Server 2008 新增T-SQL 的正确简写语法，如果你对其SQL Server 2008 数据库的新增T-SQL 的正确简写语法有兴趣了解的话，你就可以对其进行点击阅读了。
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：
- view plaincopy to clipboardprint?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 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)
以上的相关内容就是对SQL Server 2008 新增T-SQL 简写语法的介绍，望你能有所收获。
