revoke_node

Revokes query access to a node from a role.

Note that by default a node provides open query access to all roles and only an explicit grant of query access to a node can be revoked.

Available in a network database and requires the star$grant role.

Parameters:

Name	Optional	Type	Description
node$	Mandatory	Text	Node to revoke query access from
role$	Mandatory	Text	Role to be revoked

Examples:

SELECT revoke_node('mynode','myrole'); -- revokes role 'myrole' query access from 'mynode'.
