        changes. This means you should not get the thread ID and store

          This function does not work correctly if thread IDs become
          larger than 32 bits, which can occur on some systems. To avoid
          problems with
          mysql_thread_id(), do not use
          it. To get the connection ID, execute a SELECT
          CONNECTION_ID() query and retrieve the result.NoteThis function does not work correctly if thread IDs become
