Question :
I have a table which is like this.
CREATE TABLE `ad_analytics` (
`id` int(90) NOT NULL,
`ad_id` int(90) NOT NULL,
`advertiser_id` int(90) NOT NULL,
`publisher_id` int(90) NOT NULL,
`visitor_ip` varchar(250) NOT NULL,
`type_ad` varchar(90) NOT NULL,
`impression` int(90) NOT NULL,
`view` int(90) NOT NULL,
`clicks` int(90) NOT NULL,
`date_event` date NOT NULL,
`placed_date` date NOT NULL,
`ending_date` date NOT NULL,
`cpc` int(60) NOT NULL,
`cpv` int(60) NOT NULL,
`cpi` int(60) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
I want to count the number of impressions, views, and clicks for a particular id for distinct IP Aka if there are four impressions from the same IP then it should be counted as one impression for a particular IP. How can I do that?
Sample data.
INSERT INTO `ad_analytics` (`id`, `ad_id`, `advertiser_id`, `publisher_id`,
`visitor_ip`, `type_ad`, `impression`, `view`, `clicks`,
`date_event`, `placed_date`, `ending_date`, `cpc`, `cpv`, `cpi`)
VALUES
(34, 49, 113, 109, '::1', 'Video', 1, 0, 0, '2018-04-16', '0000-00-00', '0000-00-00', 0, 0, 0),
(35, 49, 113, 109, '::1', 'Video', 1, 0, 0, '2018-04-16', '0000-00-00', '0000-00-00', 0, 0, 0),
(36, 49, 113, 109, '::1', 'Video', 0, 0, 1, '2018-04-16', '0000-00-00', '0000-00-00', 0, 0, 0),
(37, 49, 113, 109, '::1', 'Video', 1, 0, 0, '2018-04-16', '0000-00-00', '0000-00-00', 0, 0, 0),
(38, 50, 113, 109, '::1', 'Video', 0, 0, 1, '2018-04-16', '0000-00-00', '0000-00-00', 0, 0, 0),
(38, 49, 113, 109, '::1', 'Video', 0, 0, 1, '2018-04-16', '0000-00-00', '0000-00-00', 0, 0, 0);
I am expecting the result like this.
ad_id Impression views click
49 1 0 1
50 0 0 1
Answer :
First you need to group by ad_id
and then group by visitor_ip
then select max for impression
, view
and click
so your query would look like
SELECT visitor_ip, ad_id,MAX(impression), MAX(view), MAX(clicks)
FROM ad_analytics
GROUP BY ad_id, visitor_ip;

as column name.
