GRANT TO

Description

The GRANT command has the following functions:

1. Grant the specified permissions to a user or role.
2. Grant the specified role to a user.

Note that.

"Grant specified roles to user" is supported in versions 2.0 and later

GRANT privilege_list ON priv_level TO user_identity [ROLE role_name]

GRANT privilege_list ON RESOURCE resource_name TO user_identity [ROLE role_name]

GRANT role_list TO user_identity

GRANT privilege_list ON WORKLOAD GROUP workload_group_name TO user_identity [ROLE role_name]

privilege_list is a list of privileges to be granted, separated by commas. Currently Doris supports the following permissions:

NODE_PRIV: Cluster node operation permissions, including node online and offline operations. User who has NODE_PRIV and GRANT_PRIV permission, can grant NODE_PRIV to other users.
ADMIN_PRIV: All privileges except NODE_PRIV.
GRANT_PRIV: Privilege for operation privileges. Including creating and deleting users, roles, authorization and revocation, setting passwords, etc.
SELECT_PRIV: read permission on the specified database or table
LOAD_PRIV: Import privileges on the specified database or table
ALTER_PRIV: Schema change permission for the specified database or table
CREATE_PRIV: Create permission on the specified database or table
DROP_PRIV: drop privilege on the specified database or table
USAGE_PRIV: access to the specified resource
SHOW_VIEW_PRIV: View permission to `view` creation statements (starting from version 2.0.3, 'SELECT_PRIV' and 'LOAD_PRIV' permissions cannot be 'SHOW CREATE TABLE view_name', has one of `CREATE_PRIV`，`ALTER_PRIV`，`DROP_PRIV`，`SHOW_VIEW_PRIV` can `SHOW CREATE TABLE view_name`) 

ALL and READ_WRITE in legacy permissions will be converted to: SELECT_PRIV,LOAD_PRIV,ALTER_PRIV,CREATE_PRIV,DROP_PRIV;
READ_ONLY is converted to SELECT_PRIV.

Permission classification:

1. Node Privilege: NODE_PRIV
2. database table permissions: SELECT_PRIV, LOAD_PRIV, ALTER_PRIV, CREATE_PRIV, DROP_PRIV
3. Resource  and workload groups Privilege: USAGE_PRIV

Priv_level supports the following four forms:

1. *.*.* permissions can be applied to all catalogs, all databases and all tables in them
2. catalog_name.*.* permissions can be applied to all databases and all tables in them
3. catalog_name.db.* permissions can be applied to all tables under the specified database
4. catalog_name.db.tbl permission can be applied to the specified table under the specified database

The catalog or database, table specified here may be not exist.

resource_name supports the following two forms:

1. * Permissions apply to all resources
2. The resource permission applies to the specified resource

The resource specified here can be a non-existing resource. In addition, please distinguish the resources here from external tables, and use catalog as an alternative if you use external tables.

workload_group_name specifies the workload group name and supports % and _ match characters, % can match any string and _ matches any single character.

user_identity:

The user_identity syntax here is the same as CREATE USER. And must be a user_identity created with CREATE USER. The host in user_identity can be a domain name. If it is a domain name, the effective time of the authority may be delayed by about 1 minute.

You can also assign permissions to the specified ROLE, if the specified ROLE does not exist, it will be created automatically.

role_list is the list of roles to be assigned, separated by commas,the specified role must exist.

Examples

1. Grant permissions to all catalog and databases and tables to the user

   GRANT SELECT_PRIV ON *.*.* TO 'jack'@'%';

2. Grant permissions to the specified database table to the user

   GRANT SELECT_PRIV,ALTER_PRIV,LOAD_PRIV ON ctl1.db1.tbl1 TO 'jack'@'192.8.%';

3. Grant permissions to the specified database table to the role

   GRANT LOAD_PRIV ON ctl1.db1.* TO ROLE 'my_role';

4. Grant access to all resources to users

   GRANT USAGE_PRIV ON RESOURCE * TO 'jack'@'%';

5. Grant the user permission to use the specified resource

   GRANT USAGE_PRIV ON RESOURCE 'spark_resource' TO 'jack'@'%';

6. Grant access to specified resources to roles

   GRANT USAGE_PRIV ON RESOURCE 'spark_resource' TO ROLE 'my_role';

7. Grant the specified role to a user

   GRANT 'role1','role2' TO 'jack'@'%';

Tips

This feature is supported since the Apache Doris 2.0 version

8. Grant the specified workload group 'g1' to user jack

   GRANT USAGE_PRIV ON WORKLOAD GROUP 'g1' TO 'jack'@'%'.

9. match all workload groups granted to user jack

   GRANT USAGE_PRIV ON WORKLOAD GROUP '%' TO 'jack'@'%'.

10. grant the workload group 'g1' to the role my_role

    GRANT USAGE_PRIV ON WORKLOAD GROUP 'g1' TO ROLE 'my_role'.

11. Allow jack to view the creation statement of view1 under db1

    GRANT SHOW_VIEW_PRIV ON db1.view1 TO 'jack'@'%';
