怎么mysql從數(shù)據(jù)庫查最近7天的數(shù)據(jù)？

MYSQL查詢一周內(nèi)的數(shù)據(jù)(最近7天的)怎么寫？

date(column_time)查詢一年：select * from table where DATE_SUB(CURDATE()， INTERVAL 1 YEAR) DATE_ADD((select createdate from tb_equity ORDER BY createdate DESC limit 1) ，INTERVAL -7 day)and (select createdate from tb_equity ORDER BY createdate DESC limit 1) >= createdate3，sql查詢表中的重復數(shù)據(jù)select * from 表名 where 字段名 in (select 字段名 from 表名 group by 字段名 HAVING COUNT(*) > 1) order by 表名

mysql查詢今天、昨天、近7天、近30天、本月、上一月的SQL語句？

試一下這個函數(shù)吧，strtotime

echo strtotime ( "-1 week") //減一周

echo strtotime ( " 1 day") //加一天

echo strtotime ( "-1 day") //減一天

echo strtotime ( "last Monday" ) //上周一

strtotime是返回一個int數(shù)字型，再date("Y-m-d")一下。
