MS Windows 2008R2でtest_user
の下にMySQL 5.5.17
というユーザーを作成しました。MySQLデータベースを除くすべてのデータベースでこのユーザーに選択権限を付与したいのですが、このインスタンス内に約200のデータベースがあることに注意してください。
編集:
EDIT2:
次のクエリの出力を実行します。
SELECT CONCAT("GRANT SELECT ON ",SCHEMA_NAME,".* TO 'test_user'@'localhost';")
FROM information_schema.SCHEMATA
WHERE SCHEMA_NAME NOT LIKE 'mysql';
200個のデータベースがあり、1つずつ付与したくない場合。それを行う最速の方法は
GRANT SELECT ON *.* TO 'test_user'@'localhost';
FLUSH PRIVILEGES;
そして、mysql dbで特権を取り消すだけです
REVOKE SELECT ON mysql.* FROM 'test_user'@'localhost' ;
FLUSH PRIVILEGES;
しかし、mysql。*で選択的にGRANTしてからREVOKEすると、その後、それは働いています

数年後、MariaDBで。私がやること:
ユーザーはmysqlを表示できますが、テーブルは表示できません。ユーザーはどのテーブルにもアクセスできないため、テーブルのロックは機能しません。
