What is SQLWarning In JDBC?

SQLWarning is a subclass of SQLException that holds database access warnings. Warnings do not stop the execution of a specific application, as exceptions do.

A warning may be retrieved on the Connection object, the Statement object, PreparedStatement and CallableStatement objects, or on the ResultSet using getWarnings method. 

SQLWarning warning = stmt.getWarnings();

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