I have the following tables:
CREATE TABLE members (
member_id int(1) unsigned NOT NULL AUTO_INCREMENT,
logged_in tinyint(1) NOT NULL,
PRIMARY KEY (member_id),
UNIQUE KEY member_id (member_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO members (member_id, logged_in) VALUES
(1, 0),
(2, 1),
(3, 1),
(4, 1),
(5, 0);
+-----------------------+
| members |
+-----------+-----------+
| member_id | logged_in |
+-----------+-----------+
| 1 | 0 |
| 2 | 1 |
| 3 | 1 |
| 4 | 1 |
| 5 | 0 |
+-----------+-----------+
CREATE TABLE team_members (
team_id int(1) unsigned NOT NULL,
member_id int(1) unsigned NOT NULL,
PRIMARY KEY (team_id,member_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO team_members (team_id, member_id) VALUES
(1, 1),
(1, 2),
(2, 3),
(2, 4),
(3, 5);
+---------------------+
| team_members |
+---------+-----------+
| team_id | member_id |
+---------+-----------+
| 1 | 1 |
| 1 | 2 |
| 2 | 3 |
| 2 | 4 |
| 3 | 5 |
+---------+-----------+
And this is the output I need to achieve:
+---------+-----------------------+
| team_id | logged_in_users_count |
+---------+-----------------------+
| 1 | 1 |
| 2 | 2 |
| 3 | 0 |
+---------+-----------------------+
I am trying the following sql query but it is not returning the expected output:
SELECT
tm.team_id,
(SELECT COUNT(m.logged_in) FROM members m WHERE m.logged_in = 1) AS logged_in_users_count
FROM
members m
INNER JOIN team_members tm ON (m.member_id = tm.member_id)
GROUP BY
tm.team_id

Answer 1

SELECT
team_members.team_id,
COUNT(members.logged_in)
FROM
team_members LEFT JOIN members
ON (team_members.member_id = members.member_id AND members.logged_in = 1)
GROUP BY
team_members.team_id;
