Select rows where 2 cells not the same I have the following table:

+----+-------+---------+---------------+
| id | owner | variant | EAN           |
+----+-------+---------+---------------+
| 1  | 101   | black   | 1111111111111 |
+----+-------+---------+---------------+
| 2  | 102   | blue    | 1111111111112 |
+----+-------+---------+---------------+
| 3  | 103   | white   | 1111111111113 |
+----+-------+---------+---------------+
| 4  | 103   | white   | 1111111111114 |
+----+-------+---------+---------------+
| 5  | 103   | black   | 1111111111115 |
+----+-------+---------+---------------+
| 6  | 104   | white   | 1111111111116 |
+----+-------+---------+---------------+
| 7  | 104   | black   | 1111111111117 |
+----+-------+---------+---------------+


I want to select all rows except the one's that have the same owner and variant

My output has to be like this:

+----+-------+---------+---------------+
| id | owner | variant | EAN           |
+----+-------+---------+---------------+
| 1  | 101   | black   | 1111111111111 |
+----+-------+---------+---------------+
| 2  | 102   | blue    | 1111111111112 |
+----+-------+---------+---------------+
| 4  | 103   | white   | 1111111111114 |
+----+-------+---------+---------------+
| 5  | 103   | black   | 1111111111115 |
+----+-------+---------+---------------+
| 6  | 104   | white   | 1111111111116 |
+----+-------+---------+---------------+
| 7  | 104   | black   | 1111111111117 |
+----+-------+---------+---------------+


Can anyone explain me how this can be done? I have tried group by but that only works on 1 column
The particular EAN to render would be determined by the database.

Assuming your tablename is august15, then 

using the sample data below

+----+-------+---------+---------------+
| id | owner | variant | EAN           |
+----+-------+---------+---------------+
| 1  | 101   | black   | 1111111111111 |
+----+-------+---------+---------------+
| 2  | 102   | blue    | 1111111111112 |
+----+-------+---------+---------------+
| 3  | 103   | white   | 1111111111113 |
+----+-------+---------+---------------+
| 4  | 103   | white   | 1111111111114 |
+----+-------+---------+---------------+
| 5  | 103   | black   | 1111111111115 |
+----+-------+---------+---------------+
| 6  | 104   | white   | 1111111111116 |
+----+-------+---------+---------------+
| 7  | 104   | black   | 1111111111117 |
+----+-------+---------+---------------+


This query
SELECT * FROM August15 GROUP BY owner, variant;
would result


+----+-------+---------+---------------+
| id | owner | variant | EAN           |
+----+-------+---------+---------------+
| 1  | 101   | black   | 1111111111111 |
+----+-------+---------+---------------+
| 2  | 102   | blue    | 1111111111112 |
+----+-------+---------+---------------+
| 5  | 103   | black   | 1111111111115 |
+----+-------+---------+---------------+
| 3  | 103   | white   | 1111111111113 |
+----+-------+---------+---------------+
| 7  | 104   | black   | 1111111111117 |
+----+-------+---------+---------------+
| 6  | 104   | white   | 1111111111116 |
+----+-------+---------+---------------+


to get exactly what you need change the query to
SELECT * FROM August15 GROUP BY owner, variant ORDER BY id ASC;

Sample Data

SET FOREIGN_KEY_CHECKS=0;

-- Table structure for august15

DROP TABLE IF EXISTS august15;
CREATE TABLE august15 (
  id int(11) NOT NULL AUTO_INCREMENT,
  owner int(11) NOT NULL,
  variant varchar(50) NOT NULL,
  ean varchar(11) CHARACTER SET latin1 COLLATE latin1_bin DEFAULT NULL,
  PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=latin1;

-- Records of august15

INSERT INTO august15 VALUES ('1', '101', 'black', '11111111111');
INSERT INTO august15 VALUES ('2', '102', 'blue', '11111111112');
INSERT INTO august15 VALUES ('3', '103', 'white', '11111111113');
INSERT INTO august15 VALUES ('4', '103', 'white', '11111111114');
INSERT INTO august15 VALUES ('5', '103', 'black', '11111111115');
INSERT INTO august15 VALUES ('6', '104', 'white', '11111111116');
INSERT INTO august15 VALUES ('7', '104', 'black', '11111111117');
