If there is only one data row, it can be like this:
SELECT * FROM user ORDER BY user_id<>7,score DESC;
Mainly "user_id<>7", the user id of 7 will be ranked first.
If there are multiple data rows:
SELECT * FROM user ORDER BY user_id NOT IN(7,8,9),score DESC;

Sort a single column first:
mysql Sort the specified value of a certain column first Sorting order by case
SELECT * FROM `jcxsw`.`t_company_product` order by ( case when id=263 then 1 ELSE 4 END),category_id desc;

Multiple columns are sorted first:
SELECT * FROM `web_membersfastsort_women` m order by m.province<>'10106000' , m.city<>'10106001' ,m.city desc,m.province desc,m.s_cid asc, m.images_ischeck desc,m.pic_num desc limit 2000,30
