title: Oracle BI (OBIEE) - Wildcard search for numeric values only
body: <p>I need to set up  a query that returns only the values that would match a pattern {Any character &amp; digit}
  I've tried setting up a filter criteria to ' %_
  [0-9] but it doesn't work...I want to exclude any results that have two letters as the first two characters of a value. 
  Thanks!</p>
