每年的节假日数据处理

需求：每年的法定节假日都是不固定的，我们需要把固定的那些日子存入数据库中，每年12月份颁布下一年的节假日，将这些节假日和调班数据更新到库表中。这样就可以知道下一年的节假日情况了

数据库表设计：

drop table if exists t_holiday_bill;

/*==============================================================*/
/* Table: t_holiday_bill                                        */
/*==============================================================*/
create table t_holiday_bill 
(
   id                   varchar(32)                    not null,"date"               varchar(20)                    null,serial_no            varchar(20)                    null,weekday              varchar(20)                    null,remark               varchar(20)                    null,pass_flag            varchar(1)                     null,constraint PK_T_HOLIDAY_BILL primary key clustered (id)
);
