--本周

SELECT * FROM 表名 WHERE YEARWEEK( date_format( 时间字段名,\'%Y-%m-%d\' ) ) = YEARWEEK( now() ) ;

--本月

SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, \'%Y%m\' ) = DATE_FORMAT( CURDATE( ) ,\'%Y%m\' )

--上一个月

SELECT * FROM 表名 WHERE PERIOD_DIFF(date_format(now(),\'%Y%m\'),date_format(时间字段名,\'%Y%m\') =1

--本年

SELECT * FROM 表名 WHERE YEAR( 时间字段名 ) = YEAR( NOW( ) )

--上一月

SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , \'%Y%m\' ) , date_format( 时间字段名, \'%Y%m\' ) ) =1

--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));

--查询当前这周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,\'%Y-%m-%d\')) = YEARWEEK(now());

--查询上周的数据

--查询当前月份的数据
select name,submittime from enterprise where date_format(submittime,\'%Y-%m\')=date_format(now(),\'%Y-%m\')

--查询距离当前现在6个月的数据
select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();

--查询上个月的数据
select name,submittime from enterprise where date_format(submittime,\'%Y-%m\')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),\'%Y-%m\')
