FDMemTable 数据集

c++builder FDMemTable 内存表

内存数据表：现在应该首选 TFDMemTable 了(之前是 TClientDataSet)

FDMemTable->CloneCursor(ds, true, true);

FDMemTable->Data = fdQuery->Data;

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

ADMemTable1.FilterChanges := [rtModified, rtInserted, rtDeleted];
ADMemTable1.Data := ADQuery1.Delta;

FDQuery1.SQL.Text := "select * from orders; select * from customers";

FDQuery1.Open;
FDQuery1.FetchAll;
// assign orders records to FDMemTable1
FDMemTable1.Data := FDQuery1.Data;

FDQuery1.NextRecordSet;
FDQuery1.FetchAll;
// assign customers records to FDMemTable2
FDMemTable2.Data := FDQuery1.Data;
