ReplicationFrequency Property

Questa funzionalità verrà rimossa in una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.

The ReplicationFrequency property sets the method used to determine article publication.

Sintassi

object
.ReplicationFrequency [= value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list.
  • value
    A long integer that specifies article publication as described in Settings.

Data Type

Long, enumerated

Modifiable

Read/write when using the SQL Distributed Management Objects (SQL-DMO) object to create a publication.

Read-only when the object references an existing publication.

Prototype (C/C++)

HRESULT GetReplicationFrequency(SQLDMO_REPFREQ_TYPE* pRetVal);
HRESULT SetReplicationFrequency(SQLDMO_REPFREQ_TYPE NewValue);

Settings

Constant Value Description

SQLDMORepFreq_Continuous

0

Log monitoring or another method is used to determine replicated article content.

SQLDMORepFreq_Snapshot

1

The article is replicated at fixed times and is not dependent upon transaction log monitoring or other monitoring processes.

SQLDMORepFreq_Unknown

1000

The value is not valid.

Osservazioni

Microsoft SQL Server supports two types of transactional replication. In the first instance, data is replicated at fixed intervals regardless of any changes made to that data. This type of transactional replication is more often identified as snapshot replication, because the data is simply copied as it exists at a given moment. Transactional replication can also determine replicated values based on changes made to that data. By default, SQL Server replication monitors changes to the transaction log of a database to determine which values are replicated.

Setting the ReplicationFrequency property controls the type of transactional replication defined by the TransPublication object and is part of creating transactional and snapshot replication publications. For more information, see TransPublication Object.
