[Swarlog]

try (Connection con = L2DatabaseFactory.getInstance().getConnection();
               PreparedStatement ps = con.prepareStatement("UPDATE clan_data SET clan_name = ? WHERE clan_id = ?"))
            {
               ps.setString(1, val);
               ps.setInt(2, st.getPlayer().getClanId());
               ps.execute();
            }
            catch (Exception e)
            {
               _log.warn("Couldn't update clan privs for old clan leader", e);
            }
            st.getPlayer().getClan().setName(val);
            
            st.getPlayer().sendMessage("Your Clan name has been changed to " + val);
            st.getPlayer().broadcastUserInfo();

val --> Es el nuevo nombre que vas a darle al clan.
 st.getPlayer().getClanId() --> Es la id del clan al que vas a cambiar el nombre.
