GRANT Statement

  • Grants privileges to ClickHouse user accounts or roles.
  • Assigns roles to user accounts or to the other roles.

To revoke privileges, use the REVOKE statement. Also you can list granted privileges with the SHOW GRANTS statement.

Granting Privilege Syntax

GRANT [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} TO {user | role | CURRENT_USER} [,...] [WITH GRANT OPTION] [WITH REPLACE 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. The WITH REPLACE OPTION clause replace old privileges by new privileges for the user or role, if is not specified it appends privileges.

Assigning Role Syntax

GRANT [ON CLUSTER cluster_name] role [,...] TO {user | another_role | CURRENT_USER} [,...] [WITH ADMIN OPTION] [WITH REPLACE OPTION]
  • role — ClickHouse user role.
  • user — ClickHouse user account.

The WITH ADMIN OPTION clause grants ADMIN OPTION privilege to user or role. The WITH REPLACE OPTION clause replace old roles by new role for the user or role, if is not specified it appends roles.

Grant Current Grants Syntax

GRANT CURRENT GRANTS{(privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*}) | ON {db.table|db.*|*.*|table|*}} TO {user | role | CURRENT_USER} [,...] [WITH GRANT OPTION] [WITH REPLACE OPTION]
  • privilege — Type of privilege.
  • role — ClickHouse user role.
  • user — ClickHouse user account.

Using the CURRENT GRANTS statement allows you to give all specified privileges to the given user or role. If none of the privileges were specified, then the given user or role will receive all available privileges for CURRENT_USER.

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:

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 does not 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

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.

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 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 privilege.

Some queries by their implementation require a set of privileges. For example, to execute the RENAME query you need the following privileges: SELECT, CREATE TABLE, INSERT and DROP TABLE.

SELECT

Allows executing SELECT 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:

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 does not 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

Allows executing INSERT 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 does not insert any data.

Example

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.
