事物回滚

总体作为一个事务，整体提交或整体回滚

BEGIN tran Price
DECLARE @tran_error int;
SET @tran_error=0;
    BEGIN try
    UPDATE t_PortGrant SET PortPrice ='200' WHERE StageID=73 AND StaffID='18440' and BasePID='1501'
    set @tran_error=@tran_error+@@error;
    update t_BaseProduct SET ImagePrice='200' where StageID=73 and BasePID='1544401'
    set @tran_error=@tran_error+@@error;
    end try
BEGIN CATCH
    PRINT '出现异常，错误编号：' + convert(varchar,error_number()) + ',错误消息：' + error_message()
    SET @tran_error = @tran_error + 1
END CATCH

IF(@tran_error > 0)
    BEGIN
        --执行出错，回滚事务
        ROLLBACK TRAN;
        PRINT '价格修改失败!';
    END
ELSE
    BEGIN
        --没有异常，提交事务
        COMMIT TRAN;
        PRINT '价格修改成功!';
    END

SET XACT_ABORT ON
BEGIN TRAN
--要执行的语句
UPDATE t_PortGrant SET PortPrice='200' WHERE StageID='73' AND StaffID='18440' AND BasePID=1501
UPDATE t_BaseProduct SET ImagePrice='200' WHERE StageID='73' AND BasePID='1234'
COMMIT TRAN
GO

其中某一条SQL语句执行出错时，则事物回滚，两天语句都不会执行操作
