MySQL error code: 1175 during UPDATE in MySQL Workbench

 It gives me the following error:

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 ....

I followed the instructions, and I unchecked the safe update option from the Edit menu then Preferences then SQL Editor. The same error still appear & I'm not able to update this value. Please, tell me what is wrong?

It looks like your MySql session has the safe-updates option set. This means that you can't update or delete records without specifying a key (ex. primary key) in the where clause.

Try:

SET SQL_SAFE_UPDATES = 0;

Or you can modify your query to follow the rule (use primary key in where clause).
