  • [ @force_invalidate_snapshot = ] force_invalidate_snapshot
    Acknowledges that the action taken by this stored procedure may invalidate an existing snapshot. force_invalidate_snapshot is a bit, with a default 0.

    0 specifies that changes to the merge article do not cause the snapshot to be invalid. If the stored procedure detects that the change does require a new snapshot, an error occurs and no changes are made.

    1 means that changes to the merge article may cause the snapshot to be invalid, and if there are existing subscriptions that would require a new snapshot, gives permission for the existing snapshot to be marked as obsolete and a new snapshot generated.

  • [ @force_reinit_subscription = ] force_reinit_subscription
    Acknowledges that the action taken by this stored procedure may require existing subscriptions to be reinitialized. force_reinit_subscription is a bit with a default of 0.

    0 specifies that changes to the merge article do not cause the subscription to be reinitialized. If the stored procedure detects that the change would require existing subscriptions to be reinitialized, an error occurs and no changes are made.

    1 means that changes to the merge article will cause existing subscriptions to be reinitialized, and gives permission for the subscription reinitialization to occur.

Return Code Values

0 (success) or 1 (failure)

Remarks

sp_changemergefilter is used in merge replication.

Changing the filter on a merge article requires the snapshot, if one exists, to be recreated. This is performed by setting the @force_invalidate_snapshot to 1. Also, if there are subscriptions to this article, the subscriptions need to be reinitialized. This is done by setting the @force_reinit_subscription to 1.

To use logical records, the publication and articles must meet a number of requirements. For more information, see Grouping Changes to Related Rows with Logical Records.
