DROP SUBSCRIPTION statement [SQL Remote]

Description 

Use this statement to drop a subscription for a user from a publication.

Syntax 

DROP SUBSCRIPTION TO publication-name [ ( subscription-value ) ]
 FOR subscriber-id, ...

subscription-value: string

subscriber-id: string

Parameters 

publication-name    The name of the publication to which the user is being subscribed. This may include the owner of the publication.

subscription-value    A string that is compared to the subscription expression of the publication. This value is required because a user may have more than one subscription to a publication.

subscriber-id    The user ID of the subscriber to the publication.

Usage 

Drops a SQL Remote subscription for a user ID to a publication in the current database. The user ID will no longer receive updates when data in the publication is changed.

In SQL Remote, publications and subscriptions are two-way relationships. If you drop a subscription for a remote user to a publication on a consolidated database, you should also drop the subscription for the consolidated database on the remote database to prevent updates on the remote database being sent to the consolidated database.

Permissions 

Must have DBA authority.

Side effects 

Automatic commit.
