Description

Each database in a SQL Remote installation is identified in outgoing messages by a publisher user ID. The current publisher user ID can be found using the CURRENT PUBLISHER special constant. The following query identifies the current publisher:

     SELECT CURRENT PUBLISHER

The REVOKE PUBLISH statement ends the identification of the named user ID as the publisher.

You should not REVOKE PUBLISH from a database while the database has active SQL Remote publications or subscriptions.

Issuing a REVOKE PUBLISH statement at a database has several consequences for a SQL Remote installation:

• You will not be able to insert data into any tables with a CURRENT PUBLISHER column as part of the primary key. publisher user ID, and so will not be accepted by recipient databases.

If you change the publisher user ID at any consolidated or remote database in a SQL Remote installation, you must ensure that the new publisher user ID is granted REMOTE permissions on all databases receiving messages from the database. This will generally require all subscriptions to be dropped and recreated.

Example

     REVOKE PUBLISH FROM publisher_ID
