DROP USERuser[,user] ...
The DROP USER statement removes
one or more MySQL accounts. It removes privilege rows for the
account from all grant tables. To use this statement, you must
have the global CREATE USER
privilege or the DELETE privilege
for the mysql database. Each account is named
using the same format as for the
GRANT statement; for example,
'jeffrey'@'localhost'. If you specify only
the user name part of the account name, a host name part of
'%' is used. For additional information about
specifying account names, see Section 12.5.1.3, “GRANT Syntax”.
With DROP USER, you can remove an
account and its privileges as follows:
DROP USER user;
Important
DROP USER does not
automatically close any open user sessions. Rather, in the
event that a user with an open session is dropped, the
statement does not take effect until that user's session is
closed. Once the session is closed, the user is dropped, and
that user's next attempt to log in will fail. This
is by design.
DROP USER does not automatically
delete or invalidate any database objects that the user created.
This applies to tables, views, stored routines, triggers, and
events.
User Comments
So DROP USER does not automatically close any open user sessions, but does it prevent that user from opening new sessions in the meantime?
