title: $wpdb->insert not working, last_query doesn't show insert "SHOW FULL COLUMNS FROM"
body: <p>I run <code>$wpdb-&gt;insert($table, $data)</code> where data is an array with column_name => value and the insert is not working. I tried <code>$wpdb-&gt;last_query</code> and something bizarre comes back:</p>
  
  <pre><code>SHOW FULL COLUMNS FROM `table_im_trying_to_insert`
  </code></pre>
  
  <p>Why is the last query not my insert?</p>
