synchronization - 同步框架 - 无法更新或删除主键表。只插入工作

Question

我正在尝试同步以下两个表。

在目标数据库中，ParentTable 无法更新或删除；但是，ChildTable 可以正确同步。

我错过了什么吗？预先感谢！

DbSyncScopeDescription scopeDesc = new DbSyncScopeDescription("Name");

scopeDesc.Tables.Add(SqlSyncDescriptionBuilder.GetDescriptionForTable("ParentTable", sqlSourceConn));
scopeDesc.Tables.Add(SqlSyncDescriptionBuilder.GetDescriptionForTable("ChildTable", sqlSourceConn));


var sqlSourceProv = new SqlSyncScopeProvisioning(sqlSourceConn, scopeDesc);
sqlSourceProv.CommandTimeout = 3600;
if (!sqlSourceProv.ScopeExists("Name"))
   sqlSourceProv.Apply();

var sqlDestinationProv = new SqlSyncScopeProvisioning(sqlDestinationConn, scopeDesc);
sqlDestinationProv.CommandTimeout = 3600;
if (!sqlDestinationProv.ScopeExists("Name"))
   sqlDestinationProv.Apply();

var destinationProvider = new SqlSyncProvider("Name", sqlDestinationConn);

var sourceProvider = new SqlSyncProvider("Name", sqlSourceConn);

destinationProvider.MemoryDataCacheSize = MemorySize;
sourceProvider.MemoryDataCacheSize = MemorySize;

destinationProvider.ApplicationTransactionSize = BatchSize;

SyncOrchestrator orch = new SyncOrchestrator();
orch.RemoteProvider = destinationProvider;
orch.LocalProvider = sourceProvider;
orch.Direction = SyncDirectionOrder.Upload;

SyncOperationStatistics stats = orch.Synchronize();

如果您有 FK 关系，则它必须在冲突期间引发错误（无法删除带有孩子的父母）...您可以通过订阅 ApplyChangeFailedEvent 来验证这一点。您可以设置冲突解决来解决问题。
