name sysname The unique name associated with the publication.
repl_freq tinyint The replication frequency:

0 = Transaction based.

1 = Scheduled table refresh.
status tinyint The status of the publication, which can be one of the following.

0 = Inactive.

1 = Active.
sync_method tinyint The synchronization method:

1 = Character bulk copy.

4 = Concurrent_c, which means that character bulk copy is used but tables are not locked during the snapshot.
snapshot_jobid binary The scheduled task ID.
enabled_for_internet bit Indicates whether the synchronization files for the publication are exposed to the Internet through FTP and other services, where 1 means that they can be accessed from the Internet.
immediate_sync_ready bit Indicates whether the synchronization files are available, where 1 means that they are available. Not supported for non-SQL Publishers.
allow_queued_tran bit Specifies whether queuing of changes at the Subscriber until they can be applied at the Publisher has been enabled. If 1, changes at the Subscriber are queued. Not supported for non-SQL Publishers.
allow_sync_tran bit Specifies whether immediate-updating subscriptions are allowed on the publication. 1 means that immediate-updating subscriptions are allowed. Not supported for non-SQL Publishers.
autogen_sync_procs bit Specifies whether the synchronizing stored procedure for immediate-updating subscriptions is generated at the Publisher. 1 means that it is generated at the Publisher. Not supported for non-SQL Publishers.
snapshot_in_defaultfolder bit Specifies whether snapshot files are stored in the default folder. If 0, snapshot files have been stored in the alternate location specified by alternate_snapshot_folder. If 1, snapshot files can be found in the default folder.
alt_snapshot_folder nvarchar(510) Specifies the location of the alternate folder for the snapshot.
pre_snapshot_script nvarchar(510) Specifies a pointer to a .sql file location. The Distribution Agent runs the pre-snapshot script before running any of the replicated object scripts when applying a snapshot at a Subscriber.
post_snapshot_script nvarchar(510) Specifies a pointer to a .sql file location. The Distribution Agent runs the post-snapshot script after all the other replicated object scripts and data have been applied during an initial synchronization.
compress_snapshot bit Specifies that the snapshot that is written to the alt_snapshot_folder location is to be compressed into the Microsoft CAB format. 0 specifies that the snapshot will not be compressed.
ftp_address sysname The network address of the FTP service for the Distributor. Specifies where publication snapshot files are located for the Distribution Agent to pick up.
ftp_port int The port number of the FTP service for the Distributor. Specifies where the publication snapshot files are located for the Distribution Agent to pick up
ftp_subdirectory nvarchar(510) Specifies where the snapshot files are available for the Distribution Agent to pick up if the publication supports propagating snapshots using FTP.
ftp_login nvarchar(256) The username used to connect to the FTP service.
ftp_password nvarchar(1048) The user password used to connect to the FTP service.
allow_dts bit Specifies that the publication allows data transformations. 1 specifies that DTS transformations are allowed. Not supported for non-SQL Publishers.
allow_anonymous bit Indicates whether anonymous subscriptions are allowed on the publication, where 1 means that they are allowed.
centralized_conflicts bit Specifies whether conflict records are stored on the Publisher:

0 = Conflict records are stored at both the publisher and at the subscriber that caused the conflict.

conflict_retention int Specifies the conflict retention period, in days. Not supported for non-SQL Publishers.
conflict_policy int Specifies the conflict resolution policy followed when the queued updating subscriber option is used. Can be one of these values:

1 = Publisher wins the conflict.

2 = Subscriber wins the conflict.

3 = Subscription is reinitialized.

Not supported for non-SQL Publishers.
queue_type int Specifies which type of queue is used. Can be one of these values:

1 = msmq, which uses Microsoft Message Queuing to store transactions.

2 = sql, which uses SQL Server to store transactions.

This column is not used by non- SQL Server Publishers.

allow_pull bit Indicates whether pull subscriptions are allowed on the publication, where 1 means that they are allowed.
retention int The amount of change, in hours, to save for the given publication.
allow_subscription_copy bit Specifies whether the ability to copy the subscription databases that subscribe to this publication has been enabled. 1 means that copying is allowed.
allow_initialize_from_backup bit Indicates if Subscribers can initialize a subscription to this publication from a backup rather than an initial snapshot. 1 means that subscriptions can be initialized from a backup, and 0 means that they cannot. For more information, see Initialize a Transactional Subscription Without a Snapshot. Not supported for non-SQL Publishers.
