update query in MYSQL stored procedure

When I execute below update query in mysql workbench It will update only 2 rows.

UPDATE usertoken SET StatusName='Completed',Id=null  where (UserId=45 and BuddyId=46) OR (UserId=46 and BuddyId=45);

but the same query inside the Stored Procedure updates the entire table.

Even I hardCoded the user id's inside the Stored procedure nothing changed.

Any Idea's?
