Question

我们刚刚升级为与SQL Server CE 3.5 SP2和SQL Server同步2.1，一切正常，除了一个问题：

当同步数据从客户端更改为SQL Server时，我们在该表上有一个AFTER INSERT, UPDATE触发器来更新称为sync_date的列值，以便将触发器更改后的值恢复为客户端（SQL Server CE 3.5），我尝试了不同的方法，这是几个：

尝试＃1：

var scope = string.Format("{0}-{1}", CommonStaticConstants.COMMON_SCOPE_BIDIRECTION, auth.ApplicationUser);
GetOrchestrator(auth, GetMachineNames(auth.ApplicationUser), scope, SyncDirectionOrder.UploadAndDownload, false).Synchronize();

尝试＃2：

var scope = string.Format("{0}-{1}", CommonStaticConstants.COMMON_SCOPE_BIDIRECTION, auth.ApplicationUser);
GetOrchestrator(auth, GetMachineNames(auth.ApplicationUser), scope, SyncDirectionOrder.Upload, false).Synchronize();
GetOrchestrator(auth, GetMachineNames(auth.ApplicationUser), scope, SyncDirectionOrder.Download, false).Synchronize();

这是GetOrchestrator()的逻辑：

private static SyncOrchestrator GetOrchestrator(LoginAuthenticator auth, string machineNames, string scopeName, SyncDirectionOrder direction, bool isRescopingRequired)
{
    if (!orchestratorMap.Keys.Contains(scopeName) || isRescopingRequired)
    {
        var destinationProxy = new SqlSyncProviderProxy(auth, machineNames, scopeName, isRescopingRequired);

        orchestrator = new SyncOrchestrator();
        var localProvider = new SqlCeSyncProvider();
        localProvider.ScopeName = scopeName;

        localProvider.Connection = new SqlCeConnection(Infrastructure.ConnectionManager.GetClientDbConnection());
        localProvider.ApplyChangeFailed += OnApplyChangeFailed;

        orchestrator.LocalProvider = localProvider;
        orchestrator.RemoteProvider = destinationProxy;
        orchestrator.Direction = direction;

        CheckIfProviderNeedsSchema((SqlCeSyncProvider)orchestrator.LocalProvider, auth, machineNames, isRescopingRequired);

        if (orchestratorMap.Keys.Contains(scopeName))
        {
            orchestratorMap.Remove(scopeName);
        }

        orchestratorMap.Add(scopeName, orchestrator);
    }

    orchestratorMap[scopeName].Direction = direction;

    return orchestratorMap[scopeName];
}

它们都不适合我，数据更改可以正确上传，但是触发器更改后的值永远不会回到客户端。

知道我在这里缺少什么吗？请让我知道我还需要提供什么其他代码。

谢谢。
