Remarks
Notification Services creates the NSSnapshotSubscriptions stored procedure in the instance database when you create the instance. When you update the instance, Notification Services recompiles the stored procedure.
This stored procedure is in the instance schema, which is specified by the SchemaName element of the instance configuration file (ICF). If no schema name is provided, the default schema is dbo.
The result set is ordered by the ApplicationName value, and then by the SubscriptionClassName value.
Permissions
Execute permissions default to members of the NSAnalysis database role, db_owner fixed database role, and sysadmin fixed server role.
Examples
The following example produces the subscriptions snapshot report for all applications hosted by an instance. In this example, the stored procedure (like all other instance objects) is in the StockInstance schema, as specified in the SchemaName element of the ICF.
