MySQL find_in_set Sith Multiple Search String | MySQL Variable With Multiple Values | MySQL Use of REGEXP | Search IN With Multiple Values

Problem is like below:

We know that find_in_set only search by a single string find_in_set('2', '2,4,6,8') In the above example, '2' is the only string used for search. So we are looking for if there is any way to use find_in_set kind of functionality and search by multiple strings, like find_in_set('2,4,6', '2,3,4,6,8,10')

The only solution is to use REGEXP

where CONCAT(",", t2.id, ",") REGEXP ",(2|4|6|8|10),"

Full query would be like below:

SELECT t1.*, SUM(t2.score) AS score_total, GROUP_CONCAT(t2.subject ORDER BY t2.id ASC) AS subjects, GROUP_CONCAT(t2.id ORDER BY t2.id ASC) AS t2_id FROM table1 t1 JOIN table2_child t2 ON (t1.id = t2.table1_id) WHERE CONCAT(",", t2.id, ",") REGEXP ",(2|4|6|8|10)," GROUP BY t1.id
