默认行为：默认为SET XACT_ABORT OFF，没有事务行为。

SET XACT_ABORT ON
SET XACT_ABORT ON分为两种：

　　1、总体作为一个事务，整体提交或整体回滚，格式为：

--创建测试表
use MyDB
CREATE TABLE student
(
stuid int NOT NULL PRIMARY KEY,
stuname varchar(50)
)
CREATE TABLE score
(
stuid int NOT NULL REFERENCES student(stuid),
score int
)
GO

--插入测试数据
INSERT INTO student VALUES (101,'zhangsan')
INSERT INTO student VALUES (102,'wangwu')
INSERT INTO student VALUES (103,'lishi')
INSERT INTO student VALUES (104,'maliu')
GO

---------------测试事务提交------------------
use MyDB
--只回滚错误行，语句还继续执行
SET XACT_ABORT OFF
BEGIN TRAN
INSERT INTO score  VALUES (101,90)
INSERT INTO score VALUES (102,78)
INSERT INTO score VALUES (107,76) /* Foreign Key Error */
INSERT INTO score VALUES (103,81)
INSERT INTO score VALUES (104,65)
COMMIT TRAN
GO
/*
stuid       score
----------- -----------
101         90
102         78
103         81
104         65

(4 row(s) affected)
*/

use MyDB
--事务终止并全部回滚
SET XACT_ABORT ON
BEGIN TRAN
INSERT INTO score  VALUES (101,90)
INSERT INTO score VALUES (102,78)
INSERT INTO score VALUES (107,76) /* Foreign Key Error */
INSERT INTO score VALUES (103,81)
INSERT INTO score VALUES (104,65)
COMMIT TRAN
GO
/*
stuid       score
----------- -----------
(0 row(s) affected)
*/

use MyDB
--事务在错误行终止，错误行回滚，错误行之前的不回滚
SET XACT_ABORT ON
BEGIN
INSERT INTO score  VALUES (101,90)
INSERT INTO score VALUES (102,78)
INSERT INTO score VALUES (107,76) /* Foreign Key Error */
INSERT INTO score VALUES (103,81)
INSERT INTO score VALUES (104,65)
END
GO
/*
stuid       score
----------- -----------
101         90
102         78
(2 row(s) affected)
*/
