I only recently learned that LIKE also supports something vaguely similar to regex character classes: SELECT * FROM customers WHERE company_name LIKE 'foo[lt]' will only return customers whose company_name is 'fool' or 'foot', while SELECT * FROM customers WHERE zipcode LIKE '12[^30]45' will return customers whose zipcode is LIKE '12_45', except '12345' and '12045'.
