sshum Posted May 10, 2011 Share Posted May 10, 2011 Hello, I have a mysql table with over 1,000,000 postcodes, and I need to select chunks of them. Ive been using the LIKE which has been fine, ie WHERE `POST_CODE`LIKE 'LS%' but I have ran into a problem in I cant do that with postcodes starting with S, as there are postcodes like SE and SY etc. I was looking online and wondered if I needed to use a regular expression, and if so how do I do it? I need to select where the postcode starts with an 'S' and has a number after it. It doesn't matter about the rest of the postcode. Any help will be greatly appreciated.
