What does the the met_office_raw_data table look like.
Using mysql client you can use the describe command like this.

mysql> describe test;
+-------+---------+------+-----+---------+-------+
| Field | Type    | Null | Key | Default | Extra |
+-------+---------+------+-----+---------+-------+
| id    | int(11) | NO   | PRI | 0       |       |
+-------+---------+------+-----+---------+-------+

1 row in set (0.00 sec)
