Please execute a "show create table user" and "show create table minfo" and post the results here so we can see what you are talking about.

You want to update user or minfo?  What column(s) do you want to update?

You can update a table utilizing a join to another table for the purposes of update.  For example: 

 

UPDATE user
JOIN minfo ON minfo.u_uid = user.u_id
SET user.some_thing = minfo.some_thing
