SQLServer 2008 新增T-SQL 簡寫文法_mssql2008

1.定義變數時可以直接賦值
DECLARE @Id int = 5
2.Insert 語句可以一次插入多行資料
INSERT INTO StateList VALUES(@Id, 'WA'), (@Id + 1, 'FL'), (@Id + 2, 'NY')
3.支援+=操作符
SET StateId += 1
完整樣本如下：

複製代碼 代碼如下:

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

結果集為：

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