int |
Specifies whether the publication supports non-SQL Server Subscribers. A value of 1 means that non-SQL Server Subscribers are supported. A value of 0 means that only SQL Server Subscribers are supported. For more information, see Non-SQL Server Subscribers. |

originator_id |
int |
Specifies an ID for a node in a peer-to-peer topology. This ID is used for conflict detection if enabled_for_p2p_conflictdetection is set to 1. For a list of IDs that have already been used, query the Mspeer_originatorid_history system table. |
p2p_continue_onconflict |
int |
Specifies whether The Distribution Agent continues to process changes when a conflict is detected. A value of 1 means that the agent continues to process changes. Warning We recommend that you use the default value of 0. When this option is set to 1, the Distribution Agent tries to converge data in the topology by applying the conflicting row from the node that has the highest originator ID. This method does not guarantee convergence. You should make sure that the topology is consistent after a conflict is detected. For more information, see "Handling Conflicts" in Conflict Detection in Peer-to-Peer Replication. |
alllow_partition_switch |
int |
Specifies whether ALTER TABLE…SWITCH statements can be executed against the published database. For more information, see Replicate Partitioned Tables and Indexes. |
replicate_partition_switch |
int |
Specifies whether ALTER TABLE…SWITCH statements that are executed against the published database should be replicated to Subscribers. This option is valid only if allow_partition_switch is set to 1. |
Return Code Values

Remarks
sp_helppublication is used in snapshot and transactional replication.
sp_helppublication will return information on all publications that are owned by the user executing this procedure.
Example
DECLARE @myTranPub AS sysname
SET @myTranPub = N'AdvWorksProductTran'
USE [AdventureWorks2012]

Permissions
Only members of the sysadmin fixed server role at the Publisher or members of the db_owner fixed database role on the publication database or users in the publication access list (PAL) can execute sp_helppublication.
For a non-SQL Server Publisher, only members of the sysadmin fixed server role at the Distributor or members of the db_owner fixed database role on the distribution database or users in the PAL can execute sp_helppublication.
