       survey_list.`status`,
       count(survey_list.`id`)AS COUNT
FROM `survey_list`
LEFT JOIN survey_summary ON survey_list.`id`=survey_summary.`survey_id`
WHERE survey_list.`survey_name` LIKE '2%'

Is it that you are looking for?

   SELECT survey_list.`id`,
           survey_list.`survey_name`,
           survey_list.`status`,
           count(survey_list.`id`)AS cnt
    FROM `survey_list`
    LEFT JOIN survey_summary ON survey_list.`id`=survey_summary.`survey_id`
    WHERE survey_list.`survey_name` LIKE '2%'
      OR survey_list.`status` LIKE '2%'
    GROUP BY survey_list.`id`
    HAVING
     cnt > 0
