mysql提供了两个函数:
from_unixtime(time_stamp) -> 将时间戳转换为日期 unix_timestamp(date) -> 将指定的日期或者日期字符串转换为时间戳
如果要查询当天的订单的记录: [plain] select count(*) from b_order Where date_format(from_unixtime(create_time),'%Y-%m-%d') = date_format(now(),'%Y-%m-%d') 也可以这样: [plain] select count(*) from b_order Where create_time >= unix_timestamp('2013-10-24 00:00:00') and create_time <= unix_timestamp('2013-10-24 23:59:59') ;
