数据仓库日期维表怎么做

最近终于有点时间了，东拼西凑的设计了一个日期维表，也是数仓设计时比较常用的。表结构如下：

dt string COMMENT '日历日期',
lunar_dt string COMMENT '农历日期',
calendar_year int COMMENT '日历年',
quarter_of_year int COMMENT '季度',
month_of_year int COMMENT '月份',
week_of_year int COMMENT '一年第几周',
dt_of_week int COMMENT '一周第几天',
dt_of_month int COMMENT '一个月第几天',
dt_of_year int COMMENT '一年第几天',
is_last_day_of_month boolean COMMENT '是否一个月最后一天',
is_weekend boolean COMMENT '是否周末日',
is_holiday boolean COMMENT '是否节假日',
holiday_cnt tinyint COMMENT '节日天数',
holiday_type tinyint COMMENT '日历天类型:1：工作日；2：周末（和假期连着按假期，因节假日调休上班按工作日算：3:元旦 4：春节 5：清明节 6：劳动节：7：端午节 8：中秋节 9：国庆'

实际落表代码没有写，只写了数据获取部分，具体实现代码如下，欢迎大佬指点~
