   mysql查詢當天的所有資訊:

  代碼如下

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

  這個有一些繁瑣,還有簡單的寫法:

  代碼如下

  select * from table where date(regdate) = curdate();

  另一種寫法沒測試過

  查詢當天的記錄

  代碼如下

  select * from hb_article_view where TO_DAYS(hb_AddTime) = TO_DAYS(NOW())

  date()函數擷取日期部分, 扔掉時間部分,然後與當前日期比較即可

  補充:本周、上周、本月、上個月份的資料

  查詢當前這周的資料

  代碼如下

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

  查詢上周的資料

  代碼如下

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

  查詢當前月份的資料

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

  查詢距離當前現在6個月的資料

  代碼如下

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

  查詢上個月的資料

  代碼如下

  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 上月最後一天

  and 下月第一天

  mysql查詢多少秒內的資料

  代碼如下

  SELECT count( * ) AS c, sum( if( logusertype =2, logusertype, 0 ) ) /2 AS a, sum( if( logusertype =3, logusertype, 0 ) ) /3 AS b

  FROM testlog WHERE UNIX_TIMESTAMP(NOW())-UNIX_TIMESTAMP( logendtime )<=30

  查詢30秒內記錄的總數,loguser等於2的記錄的總數和,和 loguser等於3的記錄的總數.

  if( logusertype =2, logusertype, 0 ) 如果logusetype等於2 就在logusertype上累加,否則加0。

  sum( if( logusertype =2, logusertype, 0 ) ) 把logusertype都累加起來。

  sum( if( logusertype =2, logusertype, 0 ) ) /2 AS a, 除以2是統計個數。

  UNIX_TIMESTAMP(NOW())計算目前時間的秒數,

  UNIX_TIMESTAMP( logendtime )計算logendtime的秒數
