撤销用户的表权限
AI agents call RevokeTablePermission to permanently remove resources in Alibabacloud Dataworks — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
| Parameter | Type | Required | Description |
|---|---|---|---|
Actions | string | Yes | 需要撤销的表的操作权限，一次撤销多种操作权限时使用逗号（,）分隔。目前仅支持撤销MaxCompute表的Select、Describe、Download等操作权限 |
TableName | string | Yes | 需要撤销权限的MaxCompute表名称 |
WorkspaceId | number | Yes | 需要撤销权限的MaxCompute表所属的DataWorks工作空间ID |
RevokeUserId | string | — | 撤销表权限的阿里云账号ID |
RevokeUserName | string | — | 撤销表权限的云账号名称。账号格式与MaxCompute的账号格式一致。-主账号为ALIYUN$+账号名。-子账号为RAM$+账号名。该参数与RevokeUserId参数配置一个即可。如果同时配置了该参数与RevokeUserId参数，但二者取值不同，则系统会以RevokeUserId参数的配置内容为准 |
MaxComputeProjectName | string | Yes | 需要撤销权限的表所在的MaxCompute项目名称 |
