MySQL Multiple COUNT in the same table in a single request - mysql

Question

I need some help with my SQL request. I have this table:
CREATE TABLE `contact` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(65) DEFAULT NULL,
`last_name` varchar(65) DEFAULT NULL,
`phonenumber` varchar(45) NOT NULL,
`avinumber` varchar(45) DEFAULT NULL,
`date` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
`source` varchar(45) NOT NULL,
`nbrtryies` int(11) NOT NULL DEFAULT '0',
`treaty_at` date DEFAULT NULL,
`comment` varchar(255) DEFAULT '',
`status` varchar(45) DEFAULT 'KO',
`campagne_id` int(11) NOT NULL,
`treated_by` int(11) DEFAULT NULL,
`nodetree_id` int(11) DEFAULT NULL,
`avi` varchar(45) DEFAULT NULL,
`sessionid` varchar(45) DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id_UNIQUE` (`id`),
KEY `fk_contact_campagne1_idx` (`campagne_id`),
KEY `fk_contact_agent1_idx` (`treated_by`),
CONSTRAINT `fk_contact_agent` FOREIGN KEY (`treated_by`) REFERENCES `user` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION,
CONSTRAINT `fk_contact_campagne1` FOREIGN KEY (`campagne_id`) REFERENCES `campagne` (`id`) ON DELETE CASCADE ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=82 DEFAULT CHARSET=latin1;
I need to count the number of the rows and the number of the rows when the column:
treated_by
has a certain value and group the result by that column
Thsi is what I did but I doesn't seem to work:
SELECT
co.treated_by AS userId,
COUNT(*) AS treated,
SUM(CASE WHEN ca.userId=1 THEN 1 ELSE 0 END) AS total
FROM
contact AS co
INNER JOIN
campagne AS ca ON ca.id = co.campagne_id
WHERE
(co.date BETWEEN '2013-07-09' AND '2014-08-15')
AND co.treated_by IN (2 , 40)
GROUP BY co.treated_by
This is what I got:
----------------------------
| userId | treated | total |
----------------------------
| 2 | 5 | 5 |
----------------------------
| 40 | 3 | 3 |
----------------------------
And I need something like:
----------------------------
| userId | treated | total |
----------------------------
| 2 | 5 | 20 |
----------------------------
| 40 | 3 | 20 |
----------------------------
Thanks a lot for your help

Answer 1

GROUP BY co.treated_by , It produces record COUNT(*) AS treated 5 and 3 , so SUM(CASE WHEN ca.userId=1 THEN 1 ELSE 0 END) AS total , It is impossible much than 20 and 20.

Answer 2

If the condition is on co.treated_by, then why does the logic contain ca.userId?
Perhaps this will work:
SELECT co.treated_by AS userId,
COUNT(*) AS treated,
SUM(co.treated_by) AS total
FROM contact co INNER JOIN
campagne ca
ON ca.id = co.campagne_id
WHERE (co.date BETWEEN '2013-07-09' AND '2014-08-15') AND
co.treated_by IN (2 , 40)
GROUP BY co.treated_by;
Note that I also replaced the calculation for total with a simpler version supported by MySQL.
