title: MySQL - Fetch rows where a field value is less than 5 chars
body: <p>I need to fetch all the rows where the 'zip' field is less than 5 characters. How can I achieve this using only SQL? I google'd first, but only found info on CHAR_LENGTH().</p>
  
  <p>ie, psudeo code: SELECT * FROM users WHERE STRLEN(zip_code) &lt; 5</p>
  
  <p>Thanks!</p>
