Hello,

I've a table called sports that contains a list of list of sports, other called seasons that contains the seasons for a specific sport and competitions that have the competitions of a specific sport and season.

I need one MySQL query to print the list of sports with how much seasons and competitions has each. My tables structure:

sports

+--------------------+------------------+------+-----+---------+----------------+
| Field              | Type             | Null | Key | Default | Extra          |
+--------------------+------------------+------+-----+---------+----------------+
| id                 | int(10) unsigned | NO   | PRI | NULL    | auto_increment |
| name               | varchar(32)      | NO   |     | NULL    |                |
| slug               | varchar(45)      | NO   |     | NULL    |                |
| description        | varchar(128)     | NO   |     | NULL    |                |
+--------------------+------------------+------+-----+---------+----------------+

seasons

+--------------------+------------------+------+-----+---------+----------------+
| Field              | Type             | Null | Key | Default | Extra          |
+--------------------+------------------+------+-----+---------+----------------+
| id                 | int(10) unsigned | NO   | PRI | NULL    | auto_increment |
| id_sport           | int(10) unsigned | NO   | MUL | NULL    |                |
| name               | varchar(32)      | NO   |     | NULL    |                |
| slug               | varchar(32)      | NO   |     | NULL    |                |
+--------------------+------------------+------+-----+---------+----------------+

competitions

+--------------------+------------------+------+-----+---------+----------------+
| Field              | Type             | Null | Key | Default | Extra          |
+--------------------+------------------+------+-----+---------+----------------+
| id                 | int(10) unsigned | NO   | PRI | NULL    | auto_increment |
| id_season          | int(10) unsigned | NO   | MUL | NULL    |                |
| name               | varchar(32)      | NO   |     | NULL    |                |
| slug               | varchar(64)      | NO   |     | NULL    |                |
| description        | varchar(128)     | YES  |     | NULL    |                |
+--------------------+------------------+------+-----+---------+----------------+

The result of my query needs to contain: sports.*, total_seasons (SUM of seasons where seasons.id_sport=sports.id) and total_competitions (SUM of competitions where competitions.id_season=seasons.id AND seasons.id_sport=sports.id).

Thank you in advance!
