Answer 1

For MySQL 8.0.4+

SELECT *
FROM
  JSON_TABLE(
          CONCAT('[', '1,2,3,4', ']'),
          "$[*]"
          COLUMNS(
              ids BIGINT(20) PATH "$"
              )
      ) AS tt

Concatenate square brackets ([]) around your string to make it into a JSON array. Then use JSON_TABLE to convert it into a table. See the MySQL JSON Table Functions for more info.
