mysql workbench : how to fix : Error Code 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column To disable safe mode, toggle the option in Preferences - SQL Editor
In my view, Safe mode, is a great feature that is exist in mysql workbench to protect you from accident deletion or update all rows, this scenario is likely to happen often, so, if the safe mode is enabled and if you decide to use update/delete all rows you most use WHERE with key or limit that way you understand what the consequences from your result.
