My table structures are:
Name: asn_number
+------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+------------+--------------+------+-----+---------+-------+
| asn | mediumint(9) | | MUL | 0 | |
| ip_address | varchar(18) | | MUL | | |
+------------+--------------+------+-----+---------+-------+
And
Name: trace
+-------+---------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+---------------+------+-----+---------+----------------+
| id | double | | PRI | NULL | auto_increment |

| sno | tinyint(4) | | | 0 | |
| asn | tinyint(4) | | MUL | 0 | |

Can someone tell me what could've gone wrong?
