title: Need a query that returns every field that contains a specified letter
body: <p>I have an SQL table with 11000 keywords in it.</p>
  
  <p>I want a query that can find fields which contain a certain letter.</p>
  
  <p>So, if I include "a" and "b" the query will select all fields which contain the letter "a" and the letter "b" somewhere in the field.</p>
