1、回滚语句1: 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
1、回滚语句1:
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
结果1:只回滚错误行,语句还继续执行。
–select * from score
101 90
102 78
103 81
104 65
2、回滚语句2:
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
结果2:事务终止并全部回滚,结果为空。
–select * from score
3、回滚语句3:
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
结果3:出现这种是因为系统把每个insert语句都看成是单独的事务,所以错误行以前的是不回滚的。
–select * from score
101 90
102 78
