1. Create Generated Column

   String generatedColumns[] = { "ID" };

   PreparedStatement stmtInsert = conn.prepareStatement(insertSQL, generatedColumns);
   

3. Use ResultSet object to fetch the GeneratedKeys on Statement

   ResultSet rs = stmtInsert.getGeneratedKeys();
   
   if (rs.next()) {
       long id = rs.getLong(1);
       System.out.println("Inserted ID -" + id); // display inserted record
