Quick question. I’m in a bit of a rush but if someone could quickly point me in the right direction I would be very very happy.
I have a field in the db, let’s call it field_a which returns a string in the format “20,50,60,80” etc.
I wish to do a query which will search in this field to see if 20 exists.
Could I use MySQL MATCH or is there a better way?
Thank you!
Just be careful you don’t get a substring of what you actually want – for example LIKE ‘%20%’ would also match ‘50,120,70’. If you’re using MySQL, you might want to use REGEXP ‘[[:<:]]20[[:>:]]’ – where the funny faces are word boundary markers that will respect break on beginning / end of string or commas so you shouldn’t get any false positives.
