How to add data from multiple tables

I suggest you to migrate data to the next strcuture:

-- ---------------------------- -- Table structure for game -- ---------------------------- DROP TABLE IF EXISTS `game`; CREATE TABLE `game` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(128) DEFAULT NULL, `active` tinyint(1) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of game -- ---------------------------- INSERT INTO `game` VALUES ('1', 'knights', '1'); INSERT INTO `game` VALUES ('2', 'blazers', '1'); -- ---------------------------- -- Table structure for player -- ---------------------------- DROP TABLE IF EXISTS `player`; CREATE TABLE `player` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(64) DEFAULT NULL, `active` tinyint(1) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of player -- ---------------------------- INSERT INTO `player` VALUES ('1', 'player1', '1'); INSERT INTO `player` VALUES ('2', 'player2', '1'); INSERT INTO `player` VALUES ('3', 'player3', '1'); INSERT INTO `player` VALUES ('4', 'player4', '1'); INSERT INTO `player` VALUES ('5', 'player5', '1'); INSERT INTO `player` VALUES ('6', 'player6', '1'); INSERT INTO `player` VALUES ('7', 'player7', '1'); INSERT INTO `player` VALUES ('8', 'player8', '1'); INSERT INTO `player` VALUES ('9', 'player9', '1'); -- ---------------------------- -- Table structure for statistics -- ---------------------------- DROP TABLE IF EXISTS `statistics`; CREATE TABLE `statistics` ( `game_id` int(11) DEFAULT NULL, `player_id` int(11) DEFAULT NULL, `points` decimal(10,2) DEFAULT NULL, KEY `player_fk` (`player_id`), KEY `game_fk` (`game_id`), CONSTRAINT `game_fk` FOREIGN KEY (`game_id`) REFERENCES `game` (`id`) ON DELETE SET NULL ON UPDATE NO ACTION, CONSTRAINT `player_fk` FOREIGN KEY (`player_id`) REFERENCES `player` (`id`) ON DELETE SET NULL ON UPDATE NO ACTION ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of statistics -- ---------------------------- INSERT INTO `statistics` VALUES ('1', '3', '23.00'); INSERT INTO `statistics` VALUES ('1', '1', '345.00'); INSERT INTO `statistics` VALUES ('1', '4', '4.00'); INSERT INTO `statistics` VALUES ('1', '2', '345.00'); INSERT INTO `statistics` VALUES ('1', '5', '23.00'); INSERT INTO `statistics` VALUES ('1', '6', '445.00'); INSERT INTO `statistics` VALUES ('1', '7', '47.00'); INSERT INTO `statistics` VALUES ('1', '8', '5.00'); INSERT INTO `statistics` VALUES ('1', '9', '523.00'); INSERT INTO `statistics` VALUES ('2', '1', '2341.00'); INSERT INTO `statistics` VALUES ('2', '2', '0.00'); INSERT INTO `statistics` VALUES ('2', '3', '56.00'); INSERT INTO `statistics` VALUES ('2', '4', '756.00'); INSERT INTO `statistics` VALUES ('2', '5', '755.00'); INSERT INTO `statistics` VALUES ('2', '6', '56.00'); INSERT INTO `statistics` VALUES ('2', '7', '345.00'); INSERT INTO `statistics` VALUES ('2', '8', '523.00'); INSERT INTO `statistics` VALUES ('2', '9', '12.00'); 

Then your can query:

SELECT game.`name`, SUM(statistics.points) FROM statistics INNER JOIN game ON game.id = statistics.game_id GROUP BY game.`id` 

You have a subquery in your SELECT clause, but you don't have a FROM clause to complete the outer query.

Also, the ; between the two subqueries, denotes the end of the SQL statement.

You can do something like:

SELECT sum1, sum2 FROM (subquery1 here) as table1, (subquery2 here) as table2; 

As in (using your example):

"SELECT sum1, sum2 FROM (SELECT kp.pts + kp2.pts2 + kp3.pts3 + kp4.pts4 + kp5.pts5 + kp6.pts6 + kp7.pts7 + kp8.pts8 + kp9.pts9 AS sum1 FROM knightsplayer AS kp JOIN knightsplayer2 AS kp2 ON kp.id = kp2.id2 JOIN knightsplayer3 AS kp3 ON kp.id = kp3.id3 JOIN knightsplayer4 AS kp4 ON kp.id = kp4.id4 JOIN knightsplayer5 AS kp5 ON kp.id = kp5.id5 JOIN knightsplayer6 AS kp6 ON kp.id = kp6.id6 JOIN knightsplayer7 AS kp7 ON kp.id = kp7.id7 JOIN knightsplayer8 AS kp8 ON kp.id = kp8.id8 JOIN knightsplayer9 AS kp9 ON kp.id = kp9.id9) as table1, (SELECT bp.pts + bp2.pts2 + bp3.pts3 + bp4.pts4 + bp5.pts5 + bp6.pts6 + bp7.pts7 + bp8.pts8 + bp9.pts9 AS sum2 FROM blazersplayer AS bp JOIN blazersplayer2 AS bp2 ON bp.id = bp2.id2 JOIN blazersplayer3 AS bp3 ON bp.id = bp3.id3 JOIN blazersplayer4 AS bp4 ON bp.id = bp4.id4 JOIN blazersplayer5 AS bp5 ON bp.id = bp5.id5 JOIN blazersplayer6 AS bp6 ON bp.id = bp6.id6 JOIN blazersplayer7 AS bp7 ON bp.id = bp7.id7 JOIN blazersplayer8 AS bp8 ON bp.id = bp8.id8 JOIN blazersplayer9 AS bp9 ON bp.id = bp9.id9) as table2;" 

Or, if you need to join the two inline views:

SELECT sum1, sum2 FROM (subquery1 here) as table1 JOIN (subquery2 here) as table2 ON (join condition); 

Keep in mind that if you do need to join the two inline views, you need to select a column (aside from sum1/sum2) to join on.
