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 op在delete或者update的时候，都可能会出现这种警告/报错，这主要是因为版本较新的MySQL是在safe-updates模式下进行sql操作的，这个模式会导致在非主键条件下无法执行update或者delete 修改方式：单独执行一条SQLtion in Preferences -> SQL Editor and reconnect.

set sql_safe_updates=0; /*取消安全模式*/
