CREATE SUBSCRIPTION statement [SQL Remote]

Use this statement to create a subscription for a user to a publication.

Syntax
CREATE SUBSCRIPTION
TO publication-name [ ( subscription-value ) ]
FOR subscriber-id
publication-name: identifier
subscription-value : string
subscriber-id: string
Parameters
  • publication-name   The name of the publication to which the user is being subscribed. This can include the owner of the publication.

  • subscription-value   A string that is compared to the subscription expression of the publication. The subscriber receives all rows for which the subscription expression matches the subscription value.

  • subscriber-id   The user ID of the subscriber to the publication. This user must have been granted REMOTE permissions.

Remarks

In a SQL Remote installation, data is organized into publications for replication. To receive SQL Remote messages, a subscription must be created for a user ID with REMOTE permissions.

If a string is supplied in the subscription, it is matched against each SUBSCRIBE BY expression in the publication. The subscriber receives all rows for which the value of the expression is equal to the supplied string.

In SQL Remote, publications and subscriptions are two-way relationships. If you create a subscription for a remote user to a publication on a consolidated database, you should also create a subscription for the consolidated database on the remote database. The extraction utility carries this out automatically.

Permissions

Must have DBA authority.

Side effects

Automatic commit.
