MySQL 数据库的所有 table 和列级权限的列表
List of all table and column level privileges for a MySQL database
列出 MySQL 数据库的所有 table 级和列级权限的最简单方法是什么？我需要知道为特定数据库授予了何种级别的自定义访问权限，以及哪些用户对某些 tables and/or 列的访问权限进行了微调。
使用 percona 工具包中的 pt-show-grants。
要列出table级权限，可以查询the INFORMATION_SCHEMA.TABLE_PRIVILEGES table.
The TABLE_PRIVILEGES table has these columns:
GRANTEE : the name of the account to which the privilege is granted, in 'user_name'@'host_name' format.
[...]
TABLE_NAME : the name of the table.
PRIVILEGE_TYPE : The privilege granted. The value can be any privilege that can be granted at the table level; [...] . Each row lists a single privilege, so there is one row per table privilege held by the grantee.
要列出列级权限，请查看 the INFORMATION_SCHEMA.COLUMN_PRIVILEGES table。
特定数据库的所有 table/column 级别权限：
SELECT * FROM `INFORMATION_SCHEMA`.`TABLE_PRIVILEGES` WHERE TABLE_SCHEMA = 'my_database';
SELECT * FROM `INFORMATION_SCHEMA`.`COLUMN_PRIVILEGES` WHERE TABLE_SCHEMA = 'my_database';
