Description 

DROP USER removes an existing user. Attempting to drop a user that does not exist results in an invalid query condition unless the IF EXISTS option is used. If the option is used, the statement will be a no-op if the user does not exist. A user must have appropriate permission to issue a DROP USER statement. Users cannot drop themselves.

Enclose the user name in single quotation marks only if it contains non-alphanumeric characters.

Examples 

Drop a user if the user exists:
DROP USER IF EXISTS boone;
Drop a user:
DROP USER montana;
