一 、关于日期查询条件用字段timestamp
A、利用date_format
date_format('timestamp
'
,'%Y%m%d')>'20140101'
DATE_FORMAT(`
timestamp
`,
'%Y-%m-%d %H:%i:%s'
)>=
'2013-03-05 00:00:00'
mysql> select * from organizationtest where date_format(created,'%Y%m%d') betwee
n '20140101' and '20140101000000';
select date_format(created,'%Y%m%d') from organizationtest where date_format(created,'%Y%m%d') betwee
n '20140101' and '20140101000000';
select date_format(created,'%Y%m%d') from organization where date_format(created,'%Y%m%d') < '201405101'
->'20140506 ;
B、利用Date
DATE('timestamp')='2014-01-01'
二 、关于日期查询条件用字段int
用unix_timestamp('2010-04-01')时间戳,存到字段中,
用FROM_UNIXTIME( 1249488000, '%Y%m%d' ) 到到时间进行显示
