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 逻辑表名
logic_column 逻辑列名
cipher_column 密文列名
assisted_query_column 辅助查询列名
like_query_column 模糊查询列名
encryptor_type 加密算法类型
encryptor_props 加密算法参数
assisted_query_type 辅助查询算法类型
assisted_query_props 辅助查询算法参数
like_query_type 模糊查询算法类型
like_query_props 模糊查询算法参数
