[PHP-DB] mySQL Query and blank fields

[Niklas Lampén]

How can I query for specified fields that has to contain atleast 2
charters?
 
Example:
Field AAA contains '' (NULL) => No match
Field BBB contains ' ' (one charter) => No match
Field CCC contains  'ab' => Match
Field DDD contains 'abcdefg' => Match
