当一个字段以逗号隔开存多个id，用sql语句取这个id对应表中的名称

SELECT
    p.id,
    p.apply_area_ids,
    GROUP_CONCAT(area.`name`)  as apply_area_names
FROM
    ap_product p 
    LEFT JOIN ap_product_company pc on pc.id = p.product_company_id
    LEFT JOIN ap_area area on FIND_IN_SET(area.id,p.apply_area_ids)
WHERE
    p.user_id = 1 and pc.is_del = 0 
    GROUP  BY p.id
