我有table:
CREATE TABLE IF NOT EXISTS `un_pl` (
`coo` double DEFAULT NULL,
`pl` varchar(255) DEFAULT NULL,
`gal` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `un_pl` (`coo`, `pl`, `gal`) VALUES
(21.33333, 'One', 'Zero'),
(22.33333, 'Mars', 'Sofar');
CREATE TABLE IF NOT EXISTS `un_tr` (
`ut_id` int(11) NOT NULL AUTO_INCREMENT,
`date` date DEFAULT NULL,
`s_p_c` double NOT NULL,
`d_c` double NOT NULL,
`tr_id` int(11) DEFAULT NULL,
`ev_t` varchar(50) DEFAULT NULL,
PRIMARY KEY (`ut_id`)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;
INSERT INTO `un_tr` (`ut_id`, `date`, `s_p_c`, `d_c`, `tr_id`, `ev_t`)
VALUES
(1, '2018-06-01', 20.33333, 21.33333, 1, 'accident'),
(2, '2018-07-02', 21.33333, 23.33333, 1, 'accident'),
(3, '2018-06-03', 21.33333, 24.33333, 1, 'accident'),
(4, '2018-06-04', 25.33333, 26.33333, 1, 'travel'),
(5, '2018-06-04', 21.33333, 26.33333, 2, 'travel'),
(6, '2018-06-04', 21.33333, 26.33333, 2, 'accident'),
(7, '2018-06-04', 21.33333, 26.33333, 2, 'travel'),
(8, '2018-06-04', 21.33333, 26.33333, 3, 'travel'),
(9, '2018-08-04', 19.33333, 26.33333, 4, 'travel');
我只需要一张唱片
select
count(distinct ut.tr_id) as un_ter,
count(case when ut.ev_t = 'accident' then 1 end) as u_t_a
from un_tr ut
left join un_pl up ON (ut.s_p_c = up.coo) or (ut.d_c = up.coo)
where up.gal = 'Zero' and date between '2018-06-01' and '2018-06-31'
group by ut.tr_id
having count(ut.ut_id)>1
但我得到的结果是:这个查询是错误的,但它显示了我所需要的
record un_ter u_t_a
1 2
1 1
我想得到结果:
record un_ter u_t_a
2 3
你能给我一些建议吗?我该怎么做?谢谢。
