用好FDMemTable代替ClientDataSet的内存表转换繁琐步骤。

 TClientDataSet *cds = new TClientDataSet(this);
  DataSetProvider1->DataSet = dm->ADOQueryPub;
  cds->ProviderName = "DataSetProvider1";
  cds->Open();

一句就可以了

FDMemTable1->CopyDataSet(dm->ADOQueryPub, TFDCopyDataSetOptions() << coStructure << coRestart << coAppend);

多用FDMemTable，不再用ClientDataSet\DataSetProvider1做转换了
