declare @iErrorCount INT
set @iErrorCount = 0
begin tran Tran1
   insert into t1(Id, c1) values(1,'1')
    set @iErrorCount=@iErrorCount+@@error

   insert into t1(Id, c1) values('XX2','2')
    set @iErrorCount=@iErrorCount+@@error

if @iErrorCount=0 
begin   
    COMMIT TRAN Tran1  --执行事务
end 
else   
begin   
    ROLLBACK TRAN Tran1  --回滚事务
end

第二种：

Begin 
　　Tran Tran1
        insert into t1(Id, c1) values(1,'1')
        insert into t1(Id, c1) values('XX2','2')  --此句产生错误
   COMMIT TRAN Tran1
END 
Try
Begin Catch 
    raiserror 50005N'出错了' 
    ROLLBACK TRAN Tran1     ---出错后调用回滚
END Catch

第三种：

SET XACT_ABORT ON ----语句产生运行时错误，则整个事务将终止并回滚。 
Begin Tran
    INSERT INTO t1(Id, c1) VALUES(1,'1')
    INSERT INTO t1(Id, c1) VALUES('XX2','2') --此句产生错误时，就会回滚整个事务
Commit Tran
