# GRANT

- Grants [privileges](#grant-privileges) to ClickHouse user accounts or roles.
- Assigns roles to user accounts or to the other roles.

To revoke privileges, use the [REVOKE](revoke.md) statement. Also you can list granted privileges with the [SHOW GRANTS](show.md#show-grants-statement) statement.

## Granting Privilege Syntax {#grant-privigele-syntax}

```sql
GRANT [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} TO {user | role | CURRENT_USER} [,...] [WITH GRANT OPTION]
```

- `privilege` — Type of privilege.
- `role` — ClickHouse user role.
- `user` — ClickHouse user account.

The `WITH GRANT OPTION` clause grants `user` or `role` with permission to execute the `GRANT` query. Users can grant privileges of the same scope they have and less.


## Assigning Role Syntax {#assign-role-syntax}

```sql
GRANT [ON CLUSTER cluster_name] role [,...] TO {user | another_role | CURRENT_USER} [,...] [WITH ADMIN OPTION]
```

- `role` — ClickHouse user role.
- `user` — ClickHouse user account.

The `WITH ADMIN OPTION` clause grants [ADMIN OPTION](#admin-option-privilege) privilege to `user` or `role`.

## Usage {#grant-usage}

To use `GRANT`, your account must have the `GRANT OPTION` privilege. You can grant privileges only inside the scope of your account privileges.

For example, administrator has granted privileges to the `john` account by the query:

```sql
GRANT SELECT(x,y) ON db.table TO john WITH GRANT OPTION
```

It means that `john` has the permission to execute:

- `SELECT x,y FROM db.table`.
- `SELECT x FROM db.table`.
- `SELECT y FROM db.table`.

`john` can't execute `SELECT z FROM db.table`. The `SELECT * FROM db.table` also is not available. Processing this query, ClickHouse doesn't return any data, even `x` and `y`. The only exception is if a table contains only `x` and `y` columns. In this case ClickHouse returns all the data.

Also `john` has the `GRANT OPTION` privilege, so it can grant other users with privileges of the same or smaller scope.

Specifying privileges you can use asterisk (`*`) instead of a table or a database name. For example, the `GRANT SELECT ON db.* TO john` query allows `john` to execute the `SELECT` query over all the tables in `db` database. Also, you can omit database name. In this case privileges are granted for current database. For example, `GRANT SELECT ON * TO john` grants the privilege on all the tables in the current database, `GRANT SELECT ON mytable TO john` grants the privilege on the `mytable` table in the current database.

Access to the `system` database is always allowed (since this database is used for processing queries).

You can grant multiple privileges to multiple accounts in one query. The query `GRANT SELECT, INSERT ON *.* TO john, robin` allows accounts `john` and `robin` to execute the `INSERT` and `SELECT` queries over all the tables in all the databases on the server.


## Privileges {#grant-privileges}

Privilege is a permission to execute specific kind of queries.

Privileges have a hierarchical structure. A set of permitted queries depends on the privilege scope.

Hierarchy of privileges:

- [SELECT](#grant-select)
- [INSERT](#grant-insert)
- [ALTER](#grant-alter)
    - `ALTER TABLE`
        - `ALTER UPDATE`
        - `ALTER DELETE`
        - `ALTER COLUMN`
            - `ALTER ADD COLUMN`
            - `ALTER DROP COLUMN`

    - `ALTER QUOTA`
    - `DROP QUOTA`
    - `CREATE SETTINGS PROFILE`

        - `SYSTEM DROP UNCOMPRESSED CACHE`
    - `SYSTEM RELOAD`
        - `SYSTEM RELOAD CONFIG`
        - `SYSTEM RELOAD DICTIONARY`
        - `SYSTEM RELOAD EMBEDDED DICTIONARIES`
    - `SYSTEM MERGES`
    - `SYSTEM TTL MERGES`
    - `SYSTEM FETCHES`
    - `SYSTEM MOVES`
    - `SYSTEM SENDS`
        - `SYSTEM DISTRIBUTED SENDS`
        - `SYSTEM REPLICATED SENDS`
    - `SYSTEM REPLICATION QUEUES`
    - `SYSTEM SYNC REPLICA`
    - `SYSTEM RESTART REPLICA`
    - `SYSTEM FLUSH`
        - `SYSTEM FLUSH DISTRIBUTED`
        - `SYSTEM FLUSH LOGS`
- [INTROSPECTION](#grant-introspection)

    - `REMOTE`
    - `YSQL`
    - `ODBC`
    - `JDBC`
    - `HDFS`
    - `S3`
- [dictGet](#grant-dictget)

Examples of how this hierarchy is treated:

- The `ALTER` privilege includes all other `ALTER*` privileges. 
- `ALTER CONSTRAINT` includes `ALTER ADD CONSTRAINT` and `ALTER DROP CONSTRAINT` privileges.

Privileges are applied at different levels. Knowing of a level suggests syntax available for privilege.

Levels (from lower to higher):

- `COLUMN` — Privilege can be granted for column, table, database, or globally.
- `TABLE` — Privilege can be granted for table, database, or globally.
- `VIEW` — Privilege can be granted for view, database, or globally.
- `DICTIONARY` — Privilege can be granted for dictionary, database, or globally.
- `DATABASE` — Privilege can be granted for database or globally.
- `GLOBAL` — Privilege can be granted only globally.
- `GROUP` — Groups privileges of different levels. When `GROUP`-level privilege is granted, only that privileges from the group are granted which correspond to the used syntax.

Examples of allowed syntax:

- `GRANT SELECT(x) ON db.table TO user`
- `GRANT SELECT ON db.* TO user`

Examples of disallowed syntax:

- `GRANT CREATE USER(x) ON db.table TO user`
- `GRANT CREATE USER ON db.* TO user`

The special privilege [ALL](#grant-all) grants all the privileges to a user account or a role.

By default, a user account or a role has no privileges.

If a user or a role has no privileges, it is displayed as [NONE](#grant-none) privilege.

Some queries by their implementation require a set of privileges. For example, to execute the [RENAME](misc.md#misc_operations-rename) query you need the following privileges: `SELECT`, `CREATE TABLE`, `INSERT` and `DROP TABLE`.


### SELECT {#grant-select}

Allows executing [SELECT](select/index.md) queries.

Privilege level: `COLUMN`.

**Description**

User granted with this privilege can execute `SELECT` queries over a specified list of columns in the specified table and database. If user includes other columns then specified a query returns no data. 

Consider the following privilege:

```sql
GRANT SELECT(x,y) ON db.table TO john
```

This privilege allows `john` to execute any `SELECT` query that involves data from the `x` and/or `y` columns in `db.table`, for example, `SELECT x FROM db.table`. `john` can't execute `SELECT z FROM db.table`. The `SELECT * FROM db.table` also is not available. Processing this query, ClickHouse doesn't return any data, even `x` and `y`. The only exception is if a table contains only `x` and `y` columns, in this case ClickHouse returns all the data.

### INSERT {#grant-insert}

Allows executing [INSERT](insert-into.md) queries.

Privilege level: `COLUMN`.

**Description**

User granted with this privilege can execute `INSERT` queries over a specified list of columns in the specified table and database. If user includes other columns then specified a query doesn't insert any data.

**Example**

```sql
GRANT INSERT(x,y) ON db.table TO john
```

The granted privilege allows `john` to insert data to the `x` and/or `y` columns in `db.table`.

### ALTER {#grant-alter}

Allows executing [ALTER](alter.md) queries according to the following hierarchy of privileges:

- `ALTER`. Level: `COLUMN`. 
    - `ALTER TABLE`. Level: `GROUP`
        - `ALTER UPDATE`. Level: `COLUMN`.  Aliases: `UPDATE`
        - `ALTER DELETE`. Level: `COLUMN`. Aliases: `DELETE`

Examples of how this hierarchy is treated:

- The `ALTER` privilege includes all other `ALTER*` privileges. 
- `ALTER CONSTRAINT` includes `ALTER ADD CONSTRAINT` and `ALTER DROP CONSTRAINT` privileges.

**Notes**

- The `MODIFY SETTING` privilege allows modifying table engine settings. It doesn't affect settings or server configuration parameters.
- The `ATTACH` operation needs the [CREATE](#grant-create) privilege.
- The `DETACH` operation needs the [DROP](#grant-drop) privilege.
- To stop mutation by the [KILL MUTATION](misc.md#kill-mutation) query, you need to have a privilege to start this mutation. For example, if you want to stop the `ALTER UPDATE` query, you need the `ALTER UPDATE`, `ALTER TABLE`, or `ALTER` privilege.
