Answer 1

If you are passing 48,52 as comma separated numbers as a string to IN then search is not performed correctly. You have to use FIND_IN_SET with column and the CSV value.

SELECT * FROM tbl_listing 
WHERE status='1' 
  and ( FIND_INSET( 48, sub_cat_id ) > 0
        OR FIND_INSET( 52, sub_cat_id ) > 0 )
ORDER BY 
  tbl_listing.company_name DESC 
LIMIT 0, 15

Refer to :

• MySQL : FIND_IN_SET( str, strlist ) : Return the index position of the first argument within the second argument

Answer 2

you can try this...

 SELECT * FROM tbl_listing WHERE status=='1' and sub_cat_id IN (48,52) ORDER BY  
 tbl_listing.company_name DESC LIMIT 0, 15;

Answer 3

try:

SELECT *
FROM tbl_listing 
WHERE status='1' and (sub_cat_id like ('%48,') or sub_cat_id like ('%52,'))
ORDER BY tbl_listing.company_name DESC LIMIT 0, 15
