Update query failing with error : 1175

Have a look at:

http://justalittlebrain.wordpress.com/2010/09/15/you-are-using-safe-update-mode-and-you-tried-to-update-a-table-without-a-where-that-uses-a-key-column/

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.

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;

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.
