title: Stripping out Non Numerical Characters using a Query
body: <p>Light user of MS Access so not a power user by any means. </p>
  
  <p>Ok, to explain what I want first of all. </p>
  
  <p>I have two tables, one with a username <code>XXX99999</code> ( 3 Alpha 5 Numeric ) and the other one just <code>99999</code> ( 5 numeric ).</p>
  
  <p>They are one in the same, for the most part I can safely drop the first 3 letters and perform what I need to 'link' using the last 5 Numeric digits only.</p>
  
  <p>I imagine doing this by a query.</p>
  
  <p>My question is, how would I mask this to build my query. </p>
  
  <p>All 5 Numeric are unique. </p>
