Answer 1

You can try on MysqlWorkbench

Go to Edit --> Preferences

Click "SQL Editor" tab and uncheck "Safe Updates" check box

Query --> Reconnect to Server (logout and then login)

I hope it is helpful for you.

Answer 2

This error means you're operating in safe update mode and therefore you have two options:

• you need to provide a where clause that includes an index for the update to be successful or
• You can disable this feature by doing SET SQL_SAFE_UPDATES = 0;

Answer 3

Have a look at:

If you want to update without a where key you must execute

SET SQL_SAFE_UPDATES=0;

right before your query.

Another option is to rewrite your query o include a key.

Answer 4

In MySQL 5.5, if you're using MySQL Workbench then

• Go to Edit --> Preferences
• Click "SQL Queries" tab and uncheck "Safe Updates" check box.
• Query --> Reconnect to Server (logout and then login)

This works.
