SHOW MASK RULES
描述
SHOW MASK RULES 语法用于查询指定逻辑库中的数据脱敏规则。
语法
ShowMaskRule::=
'SHOW' 'MASK' 'TABLE'? ('RULE' ruleName | 'RULES') ('FROM' databaseName)?
ruleName ::=
identifier
databaseName ::=
identifier补充说明
- 未指定
databaseName时，默认是当前使用的DATABASE， 如果也未使用DATABASE则会提示No database selected。
返回值说明
| 列 | 说明 |
|---|---|
| table | 表名 |
| column | 列名 |
| algorithm_type | 数据脱敏算法类型 |
| algorithm_props | 数据脱敏算法参数 |
示例
- 查询指定逻辑库中的所有数据脱敏规则
SHOW MASK RULES FROM mask_db;mysql> SHOW MASK RULES FROM mask_db;
+---------+----------+------------------+--------------------------------+
| table | column | algorithm_type | algorithm_props |
+---------+----------+------------------+--------------------------------+
| t_mask | phoneNum | MASK_FROM_X_TO_Y | to-y=2,replace-char=*,from-x=1 |
| t_mask | address | MD5 | |
| t_order | order_id | MD5 | |
| t_user | user_id | MASK_FROM_X_TO_Y | to-y=2,replace-char=*,from-x=1 |
+---------+----------+------------------+--------------------------------+
4 rows in set (0.01 sec)- 查询当前逻辑库中的所有数据脱敏规则
