title: How can I determine if the column name exist in the ResultSet?
body: <p>As the <code>ResultSet</code> contains the data returned from the dynamic SQL, if there are any method to determine if the <code>ResultSet</code> contains a particular column name?</p>
  <p>For example , if I run <code>rs.getString(&quot;Column_ABC&quot;)</code> but <code>&quot;Column_ABC&quot;</code> does not really exist, it will throw out the exception.</p>
  <p>How can I test if the <code>ResultSet</code> can get a data from a column named <code>&quot;Column_ABC&quot;</code>?</p>
