Warning:
As of April 12, 2019, CockroachDB v1.1 is no longer supported. For more details, refer to the Release Support Policy.

The GRANT statement lets you control each user's SQL privileges for interacting with specific databases and tables.

For privileges required by specific statements, see the documentation for the respective SQL statement.

Synopsis

GRANT ALL CREATE DROP GRANT SELECT INSERT DELETE UPDATE , ON TABLE table_name , DATABASE database_name , TO user_name ,

Required Privileges

The user granting privileges must have the GRANT privilege on the target databases or tables.

Supported Privileges

Users can be granted the following privileges. Some privileges are applicable both for databases and tables, while other are applicable only for tables (see Levels in the table below).

  • When a user is granted privileges for a database, new tables created in the database will inherit the privileges, but the privileges can then be changed.
  • When a user is granted privileges for a table, the privileges are limited to the table.
  • The root user is automatically assigned the ALL privilege for new databases and is the only user allowed to create databases.
  • For privileges required by specific statements, see the documentation for the respective SQL statement.
Privilege Levels

Parameters

Parameter Description
table_name A comma-separated list of table names. Alternately, to grant privileges to all tables, use *. ON TABLE table.* grants apply to all existing tables in a database but will not affect tables created after the grant.
database_name A comma-separated list of database names.

Privileges granted on databases will be inherited by any new tables created in the databases, but do not affect existing tables in the database.
user_name A comma-separated list of users.
