mysql查詢數據
發布日期:2016-4-27 13:4:5

  本文介紹了mysql查詢今天、昨天、7天、近30天、本月、上一月數據的方法,參考代碼已給出:

  1.今天

  select * from 表名 where to_days(時間字段名) = to_days(now());

  2.昨天

  SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 時間字段名) <= 1

  3.7天

  SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(時間字段名)

  4.近30天

  SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(時間字段名)

  5.本月

  SELECT * FROM 表名 WHERE DATE_FORMAT( 時間字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )

  6.上一月

  SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 時間字段名, '%Y%m' ) ) =1

  #查詢本季度數據

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

  #查詢上季度數據

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

  #查詢本年數據

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

  #查詢上年數據

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

  8.查詢當前這周的數據

  參考代碼如下所示:

  SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());

  8.查詢上周的數據

  參考代碼如下所示:

  SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;

  10.查詢當前月份的數據

  參考代碼如下所示:

  select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')

  11.查詢距離當前現在6個月的數據

  參考代碼如下所示:

  select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();

  12.查詢上個月的數據

  參考代碼如下所示:

  select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m')

  select * from ` user ` where DATE_FORMAT(pudate, ' %Y%m ' ) = DATE_FORMAT(CURDATE(), ' %Y%m ' ) ;

  select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = WEEKOFYEAR(now())

  select *

  from user

  where MONTH (FROM_UNIXTIME(pudate, ' %y-%m-%d ' )) = MONTH (now())

  select *

  from [ user ]

  where YEAR (FROM_UNIXTIME(pudate, ' %y-%m-%d ' )) = YEAR (now())

  and MONTH (FROM_UNIXTIME(pudate, ' %y-%m-%d ' )) = MONTH (now())

  select *

  from [ user ]

  where pudate between 上月最后一天

  and 下月第一天

  where date(regdate) = curdate();

  select * from test where year(regdate)=year(now()) and month(regdate)=month(now()) and day(regdate)=day(now())

  SELECT date( c_instime ) ,curdate( )

  FROM `t_score`

  WHERE 1

  LIMIT 0 , 30
