datetime类型

CREATE TABLE `test_date` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `create_time` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=29 DEFAULT CHARSET=utf8;

‘create_time’为datetime类型sql

select * from test_date where create_time BETWEEN '2018-10-16' AND '2018-10-28'

查询出来的数据,包含‘2018-10-28 00:00:00 ’,不包括' 2018-10-28 01:00:00 'spa

若是是datetime的'2018-10-28' 会被转成'2018-10-28 00:00:00'类型，因此查不出来2018-10-28的数据。3d

能够经过精确到秒查code

select * from test_date where create_time BETWEEN '2018-10-16 00:00:00' AND '2018-10-28 23:59:59'
