title: SQL COUNT function for results "greater than or equal to"
body: <p>I currently have a query where it returns the total number of accounts each customer holds, but how do I make it so that it returns only customers who  has more than 1 account?</p>
  
  <pre><code>SELECT C.customerID, COUNT(O.accNumber) AS "total"
  FROM Customer C, Owns O
  WHERE C.customerID = O.customerID
  GROUP BY C.customerID
  </code></pre>
