Answer 1

For getting your expected results:

This is what your query will look like (Using GROUP BY AND GROUP_CONCAT )

SELECT i.*, GROUP_CONCAT(c.category_name) FROM institute i, category c 
WHERE FIND_IN_SET(c.category_id, i.institute_category) 
GROUP BY i.institute_category

Answer 2

Use group_concat function:

SELECT i.*, group_concat(c.category_name) FROM institute i, category c
WHERE FIND_IN_SET(c.category_id, i.institute_category)
