why are not using any where condition in the update statment
WHERE clauses are not required. Performing a command without one will
affect ever row on the table.

Good morning,
I have an application where the user ids were stored lowercase.
Some batch import, in the user table some users stored a uppercase
id, and for some applicative logic, in other tables that have a
foreign key to the user table, their user ids are stored lowercase.
...
Have you any idea how to solve this situation without
stopping/recreating the DB? (it's a production environment)
Thanks
Have you tried ?
SET foreign_key_checks=0;
http://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_foreign_key_checks
If that does not work, you would need to first un-create your Foreign
Key relationships, update your key values (the USER_ID fields), then
re-create your Foreign Key relationships.
