MySQL建立日期字典表

建立表：

create table dic_date(

date date

,year int
,month int
,day int
,dayofyear int
,dayofmonth int

,weekofmonth int
,create_datetime timestamp default now() comment '資料建立日期'
) comment '日期字典表' ;

alter table dic_date add index index_dic_date_date (date);

alter table dic_date add index index_dic_date_str_date (str_date);
alter table dic_date add index index_dic_date_local_date (local_date);
