How to Retrieve Warnings?

SQLWarning objects are a subclass of SQLException that deal with database access warnings. Warnings do not stop the execution of an application, as exceptions do; they simply alert the user that something did not happen as planned. A warning can be reported on a Connection object, a Statement object (including PreparedStatement and CallableStatement objects), or a ResultSet object. Each of these classes has a getWarnings method, which you must invoke in order to see the first warning reported on the calling object

 
SQLWarning warning = stmt.getWarnings();
if (warning != null)
{
    while (warning != null)
	{
System.out.println("Message: " + warning.getMessage());
System.out.println("SQLState: " + warning.getSQLState());
	System.out.print("Vendor error code: ");
	System.out.println(warning.getErrorCode());
	warning = warning.getNextWarning();
		}
	}
