  <p>`Error: ER_BAD_FIELD_ERROR: Unknown column '2525' in 'field list'
  Fields are varchar(32) for both CONVERSATION_ID and FC_CONTACTNAME and ints for the 2 others.</p>
  
  <p>What's wrong with this query? I even put the backticks around <code>CONVERSATION_ID</code> and it thinks the <code>convID</code> variable is a column...</p>
  
  <p>Edit:</p>
  
  <p>If my query is just that, then it works:</p>
  
  <pre><code>        var sql = "INSERT INTO contacts (`FK_OWNERID`, `FK_USERID`, `FC_CONTACTNAME`)
                   VALUES (" + mysql.escape(userId) + "," + mysql.escape(contactId) + "," + mysql.escape(contactUsername) + "),
                   (" + mysql.escape(contactId) + "," + mysql.escape(userId) + "," + mysql.escape(username) + ")";
  </code></pre>
