查询本周记录

select * from ht_invoice_information where WEEKOFYEAR(create_date)=WEEKOFYEAR(NOW())

#查询上周记录

select * from ht_invoice_information where create_date>=date_add(now(),interval -(8 + weekday(now())) day)

and create_date<=date_add(now(),interval -(1 + weekday(now())) day)

#或者

select * from `ht_invoice_information` where WEEKOFYEAR(create_date)=WEEKOFYEAR(DATE_SUB(now(),INTERVAL 1 week))

#查询本月数据

select * from ht_invoice_information where MONTH(create_date)=MONTH(NOW()) and year(create_date)=year(now())

#查询上月数据

select * from ht_invoice_information where create_date<=last_day(date_add(now(),interval -1 MONTH))

and create_date>=DATE_FORMAT(concat(extract(year_month from date_add(now(),interval -1 MONTH)),'01'),'%Y-%m-%d')

#或者

select * from `ht_invoice_information` where MONTH(create_date)=MONTH(DATE_SUB(NOW(),interval 1 month))

and year(create_date)=year(now())

#查询本季度数据

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now())

#查询上季度数据

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER))

#查询本年数据

select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW())

#查询上年数据

select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year))

参考这个吧，很全了。
