Question

我正在尝试使用RMO编程创建一个合并复制，我从here获得了！

        string publisherName = "DataSourceName";
        string publicationName = "AdvWorksSalesOrdersMerge";
        string publicationDbName = "AdventureWorksDW2008R2";
        ReplicationDatabase publicationDb;
        MergePublication publication;
        // Create a connection to the Publisher.
        ServerConnection conn = new ServerConnection(publisherName);
          try
        {
             //Connect to the Publisher.
            conn.Connect();

            // Enable the database for merge publication.               
            publicationDb = new ReplicationDatabase(publicationDbName, conn);
            if (publicationDb.LoadProperties())
            {
                if (!publicationDb.EnabledMergePublishing)
                {
                    publicationDb.EnabledMergePublishing = true;
                }
            }
            else
            {
               //  Do something here if the database does not exist. 
                throw new ApplicationException(String.Format(
                    "The {0} database does not exist on {1}.",
                    publicationDb, publisherName));
            }

            // Set the required properties for the merge publication.
            publication = new MergePublication();
            publication.ConnectionContext = conn;
            publication.Name = publicationName;
            publication.DatabaseName = publicationDbName;

            // Enable precomputed partitions.
            publication.PartitionGroupsOption = PartitionGroupsOption.True;

             //Specify the Windows account under which the Snapshot Agent job runs.
            // This account will be used for the local connection to the 
            // Distributor and all agent connections that use Windows Authentication.

              publication.SnapshotGenerationAgentProcessSecurity.Login = userid;
               publication.SnapshotGenerationAgentProcessSecurity.Password = password;

             //Explicitly set the security mode for the Publisher connection
            // Windows Authentication (the default).
            publication.SnapshotGenerationAgentPublisherSecurity.WindowsAuthentication = true;

             //Enable Subscribers to request snapshot generation and filtering.
            publication.Attributes |= PublicationAttributes.AllowSubscriberInitiatedSnapshot;
            publication.Attributes |= PublicationAttributes.DynamicFilters;

            // Enable pull and push subscriptions.
            publication.Attributes |= PublicationAttributes.AllowPull;
            publication.Attributes |= PublicationAttributes.AllowPush;

            if (!publication.IsExistingObject)
            {
                 //Create the merge publication.
                publication.Create();

                // Create a Snapshot Agent job for the publication.
                publication.CreateSnapshotAgent();
            }
            else
            {
                throw new ApplicationException(String.Format(
                    "The {0} publication already exists.", publicationName));
            }

        }

        catch (Exception ex)
        {
             //Implement custom application error handling here.
            throw new Exception(String.Format("The publication {0} could not be created.", publicationName), ex);

        }
        finally
        {
            conn.Disconnect();
        }

但在这一行

publicationDb.EnabledTransPublishing = true;

我收到错误 - “ 执行Transact-SQL语句或批处理时发生异常。 ”

所以请帮我解决这个问题。

等待你的答案..

你可能现在已经回答了问题，但对于那些可能会问同样问题的人。这是因为您使用的是SQL Server的快速版本，并且无法在任何版本的SQl Server Express中创建发布者/分发者。

您的代码中的实例没有有效的实例，因此会引发异常。

看看：

和说

的行

Microsoft SQL Server 2008 Express可以作为所有类型复制的订阅者，提供了一种将数据分发到使用此版本SQL Server的客户端应用程序的便捷方法。在复制拓扑中使用SQL Server Express时，请记住以下注意事项： SQL Server Express不能用作发布服务器或分发服务器。但是，合并复制允许在发布服务器和订阅服务器之间双向复制更改。块引用

使用RMO的SQL Server Express 2008合并复制导致“执行Transact-SQL语句或批处理时发生异常”。错误？
