例如下面這樣
三個database(test1/test2/test3)都授權給同一個用戶account在localhost下使用,只是個別授權的認證密碼不同
請問這樣會不會有什麼其他問題?

mysql>GRANT ALL PRIVILEGES ON test1.* TO account@localhost IDENTIFIED BY "password1";
mysql>GRANT ALL PRIVILEGES ON test2.* TO account@localhost IDENTIFIED BY "password2";
mysql>GRANT ALL PRIVILEGES ON test3.* TO account@localhost IDENTIFIED BY "password3";
