update tp_user
set head_img='图片1'
where id IN(
select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);
update tp_user
set head_img='图片2'
where id IN(
select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);
update tp_user
set head_img='图片3'
where id IN(
select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);

以上代码执行即可，此前写了蜻蜓q系统如何随机加入头像，由于松鼠短视频字段不同因此也列一个方便大家使用。

自己使用记录：

update tp_user
set head_img='http://qingtingcun.youyacao.com/qiniu_202110270837516589514941.png'
where id IN(
select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);
update tp_user
set head_img='http://qingtingcun.youyacao.com/qiniu_202110270835149436524711.png'
where id IN(
    select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);
update tp_user
set head_img='http://qingtingcun.youyacao.com/qiniu_202110270834429074265079.png'
where id IN(
    select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);
update tp_user
set head_img='http://qingtingcun.youyacao.com/qiniu_202110270836314036839413.png'
where id IN(
select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);
update tp_user
set head_img='http://qingtingcun.youyacao.com/qiniu_202110270836157965414975.png'
where id IN(
    select A.* from(select id from tp_user where head_img='' order by rand() limit 10) AS A
);
update tp_user
set head_img='http://qingtingcun.youyacao.com/qiniu_202110270835431933928235.png'
