| allow_synctoalternate | bit | Specifies whether an alternate synchronization partner is allowed to synchronize with this Publisher. 0 means that a synchronization partner is not allowed. |
| validate_subscriber_info | nvarchar(500) | Lists the functions that are being used to retrieve Subscriber information and validate the parameterized row filtering criteria on the Subscriber. |
| ad_guidname | sysname | Specifies whether the publication is published in the Microsoft Active Directory. A valid GUID specifies that the publication is published in the Active Directory, and the GUID is the corresponding Active Directory publication object objectGUID. If NULL, the publication is not published in Active Directory. |
| backward_comp_level | int | Database compatibility level. Can be one of the following values: 90 = SQL Server 2005 (9.x). 100 = SQL Server 2008 (10.0.x). |
| max_concurrent_merge | int | The maximum number of allowed concurrent merge processes. A value of 0 for this property means that there is no limit to the number of concurrent merge processes running at any given time. This property sets a limit as to the number of concurrent merge processes that can be run against a merge publication at one time. If there are more snapshot processes scheduled at the same time than the value allows to run, then the excess jobs will be put into a queue and wait until a currently-running merge process finishes. |
| max_concurrent_dynamic_snapshots | int | The maximum number of allowed concurrent filtered data snapshot sessions that can be running against the merge publication. If 0, there is no limit to the maximum number of concurrent filtered data snapshot sessions that can run simultaneously against the publication at any given time. This property sets a limit as to the number of concurrent snapshot processes that can be run against a merge publication at one time. If there are more snapshot processes scheduled at the same time than the value allows to run, then the excess jobs will be put into a queue and wait until a currently-running merge process finishes. |
| use_partition_groups | smallint | Specifies whether the publication uses precomputed partitions. |
| dynamic_filters_function_list | nvarchar(500) | A semi-colon delimited list of functions used in the publication's parameterized row filters. |
| partition_id_eval_proc | sysname | Specifies the name of the procedure run by the Merge Agent of a Subscriber to determine its assigned partition ID. |
| publication_number | smallint | Specifies the identity column that provides a 2-byte mapping to pubid. pubid is a globally unique identifier for a publication, whereas publication number is unique only in a specified database. |
| replicate_ddl | int | Indicates whether schema replication is supported for the publication. 0 = DDL statements are not replicated. 1 = DDL statements executed at the publisher are replicated. For more information, see Make Schema Changes on Publication Databases. |
| allow_subscriber_initiated_snapshot | bit | Indicates that Subscribers can initiate the process that generates the snapshot for a publication using parameterized filters. 1 indicates that Subscribers can initiate the snapshot process. |
| dynamic_snapshot_queue_timeout | int | Specifies how many minutes a Subscriber must wait in the queue for the snapshot generation process to begin when using parameterized filters. |
| dynamic_snapshot_ready_timeout | int | Specifies how many minutes a Subscriber waits for the snapshot generation process to be completed when using parameterized filters. |
| distributor | sysname | The name of the Distributor for the publication. |
| snapshot_jobid | binary(16) | Identifies the agent job that generates the snapshot when the Subscriber can initiate the snapshot generation process. |
| allow_web_synchronization | bit | Specifies whether the publication is enabled for Web synchronization, where 1 means that Web synchronization is enabled for the publication. |
| web_synchronization_url | nvarchar(500) | Specifies the default value of the Internet URL used for Web synchronization. |
| allow_partition_realignment | bit | Indicates whether deletes are sent to the subscriber when modification of the row on the publisher causes it to change its partition. 0 = Data from an old partition will be left on the subscriber, where changes made to this data on the publisher will not replicate to this Subscriber, but changes made on the Subscriber will replicate to the Publisher. 1 = Deletes to the Subscriber to reflect the results of a partition change by removing data that is not longer part of the Subscriber's partition. For more information, see sp_addmergepublication (Transact-SQL). Note: Data that remains at the Subscriber when this value is 0 should be treated as if it were read-only; however, this is not strictly enforced by the replication system. |
| retention_period_unit | tinyint | Defines the unit used when defining retention, which can be one of these values: 0 = Day. 1 = Week. 2 = Month. 3 = Year. |
| decentralized_conflicts | int | Indicates whether the conflict records are stored at the Subscriber that caused the conflict: 0 = Conflict records are not stored at the Subscriber. 1 = Conflict records are stored at the Subscriber. |
| generation_leveling_threshold | int | Specifies the number of changes contained in a generation. A generation is a collection of changes that are delivered to a Publisher or Subscriber. |
