It seems like your MySql session has the [safe-updates][1] option set. This means it can't update or delete records without specifying a key (ex. `primary key`) in the `where` clause. If you don't want to specify the key in the `where` clause then executes the below code first and then try executing your query.
`SET SQL_SAFE_UPDATES = 0;`

It looks like your MySql session has the [safe-updates option][1] 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`).
