When you execute the update/delete request in MySQL workbench and you got the message error as:

You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column

And in MySQL Workbench also mention how we solve this issue as well by following message:

To disable safe mode, toggle the option in Preferences -> SQL Editor -> Query Editor and reconnect

Every found that kind of error when trying to update rows in MySQL? It’s because you tried to update a table without a WHERE that uses a KEY column. In my case, I don’t use even WHERE clause:

delete from order_detail;

delete from order;

Any way, the quick fix is to add SET SQL_SAFE_UPDATES=0; before your update/delete query.

SET SQL_SAFE_UPDATES=0;
delete from order_detail;

delete from order;

Or follow what MySQL Workbench mentioned as here:

To disable safe mode, toggle the option in Preferences -> SQL Editor -> Query Editor and reconnect

Here is the screenshot in MySQL Workbench 5.2.40 CE

 

It might help for those who first experience with MySQL Workbench.
