Hi I've a number of different postal codes in a system for example
WC1B 5JA WC1H 8EJ W1J 7BX W1H 7DL NW1 1NY I can use like statements for example SELECT * FROM postal_codes WHERE zip LIKE 'W1%' giving me W1J 7BX W1H 7DL In addition I have a number of abbreviated postal codes like W1 WC1 WC2 NW1 Now, if I know the postal code W1J 7BX what is the best way using a MySQL query to get the abbreviated postal codes W1. Same if I have the postal code WC1H 8EJ, how do I get the abbreviated postal codes WC1 Can I use any matching patterns ? Thanks, Neil
