title: Google query multiple columns references
body: <p>I have this query:
  <code>=QUERY(all!A:Z, "select B where (B=1 and H=true)")</code></p>
  
  <p>How can I turn <code>B</code> and <code>H</code> into a column reference so I don't have to write them when I copy the query to new cells.</p>
  
  <p>Note: column B is a number, meanwhile H contains boolean values.</p>
