開發十年，就只剩下這套架構體系了！ >>>   

今天：

SELECT * FROM A WHERE create_time = create_time(now());

昨天：

SELECT * FROM A WHERE TO_DAYS( NOW( ) ) - TO_DAYS( create_time) <= 1;

最近7天：

SELECT * FROM A where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(create_time);
 

本週資料：

SELECT * FROM A WHERE YEARWEEK(date_format(create_time,'%Y-%m-%d')) = YEARWEEK(now());

上週資料：

SELECT * FROM A WHERE YEARWEEK(date_format(create_time,'%Y-%m-%d')) = YEARWEEK(now())-1;

最近30天：

SELECT * FROM A where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(create_time);

本月：

SELECT * FROM A WHERE DATE_FORMAT( create_time, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' );
 

上一月：

SELECT * FROM A WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format(create_time, '%Y%m' ) ) =1;

本季度資料：

SELECT * FROM A WHERE QUARTER(create_time)=QUARTER(now());

距離當前6個月的資料：

SELECT * FROM A WHERE create_time BETWEEN date_sub(now(),INTERVAL 6 MONTH) AND now();

上季度資料：

SELECT * FROM A WHERE QUARTER(create_time)=QUARTER(DATE_SUB(now(),INTERVAL 1 QUARTER));
 

本年度資料：

SELECT * FROM A WHERE YEAR(create_time)=YEAR(NOW());

上年度資料：

SELECT * FROM A WHERE YEAR(create_time)=YEAR(date_sub(now(),INTERVAL 1 YEAR));
