mysql日期函数的使用

mysql中想获取日期是当天的记录，由于日期存的是日期加时间。所以需要函数处理一下，这里有两种写法

第一种使用date() ，date()函数获取日期部分, 扔掉时间部分，然后与当前日期比较即可

SELECT
as_ff_vote_record.id as as_ff_vote_record_id,
as_ff_vote_record.anchor_id as as_ff_vote_record_anchor_id,
as_ff_vote_record.phone as as_ff_vote_record_phone,
as_ff_vote_record.vote_time as as_ff_vote_record_vote_time
FROM
ff_vote_record as_ff_vote_record
WHERE
date(as_ff_vote_record.vote_time) = CURDATE()
and
phone = 'xxxxxxx'

第二种是使用DATE_FORMAT(字段, '时间格式')来转化

SELECT
as_ff_vote_record.id as as_ff_vote_record_id,
as_ff_vote_record.anchor_id as as_ff_vote_record_anchor_id,
as_ff_vote_record.phone as as_ff_vote_record_phone,
as_ff_vote_record.vote_time as as_ff_vote_record_vote_time
FROM
ff_vote_record as_ff_vote_record
WHERE
DATE_FORMAT(as_ff_vote_record.vote_time, '%Y-%m-%d') = CURDATE()
and
phone = 'xxxxxxx'
