MySQL Volleyball Standings
- by Torez
I have a database table full of game by game results and want to know if I can calculate the following:
GP (games played)
Wins
Loses
Points (2 points for each win, 1 point for each lose)
Here is my table structure:
CREATE TABLE `results` (
`id` int(10) unsigned NOT NULL auto_increment,
`home_team_id` int(10) unsigned NOT NULL,
`home_score` int(3) unsigned NOT NULL,
`visit_team_id` int(10) unsigned NOT NULL,
`visit_score` int(3) unsigned NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;
And a few testing results:
INSERT INTO `results` VALUES(1, 1, 21, 2, 25);
INSERT INTO `results` VALUES(2, 3, 21, 4, 17);
INSERT INTO `results` VALUES(3, 1, 25, 3, 9);
INSERT INTO `results` VALUES(4, 2, 7, 4, 22);
INSERT INTO `results` VALUES(5, 1, 19, 4, 20);
INSERT INTO `results` VALUES(6, 2, 24, 3, 26);
Here is what a final table would look like:
+-------------------+----+------+-------+--------+
| Team Name | GP | Wins | Loses | Points |
+-------------------+----+------+-------+--------+
| Spikers | 4 | 4 | 0 | 8 |
| Leapers | 4 | 2 | 2 | 6 |
| Ground Control | 4 | 1 | 3 | 5 |
| Touch Guys | 4 | 0 | 4 | 4 |
+-------------------+----+------+-------+--------+
