sp_showpendingchanges (Transact-SQL)

  • Стаття

Applies to: SQL Server

Returns a result set showing the changes that are waiting to be replicated. This stored procedure is executed at the Publisher on the publication database and at the Subscriber on the subscription database.

Transact-SQL syntax conventions

Note

This procedure provides an approximation of the number of changes and the rows that are involved in those changes. For example, the procedure retrieves information from either the Publisher or Subscriber, but not both at the same time. Information that is stored at the other node might result in a smaller set of changes to synchronize than the procedure estimates.

    [ [ @destination_server = ] N'destination_server' ]
    [ , [ @publication = ] N'publication' ]
    [ , [ @article = ] N'article' ]
