More information and resources on TFDMemTable from the FireDAC Skill Sprint.
If you missed the Skill Sprint, or want to review it, here is the video with the recording of the Q&A. The presentation is 15-20 minutes, and the other 30 minutes is from the Q&A.
Here are the slides for now, the replay will be available soon.
Common code samples:
Delphi / Object Pascal
// Create Field Definitions FDMemTable1.FieldDefs.Add('ID', ftInteger, 0, False); FDMemTable1.FieldDefs.Add('Name', ftString, 20, False); FDMemTable1.CreateDataSet; // Append data FDMemTable1.Open; FDMemTable1.AppendRecord([1, 'Jim']); // Load from another DataSet FDMemTable1.CopyDataSet(DataSet1, [coStructure, coRestart, coAppend]);
C++
// Create Field Definitions FDMemTable1->FieldDefs->Add("ID", ftInteger, 0, False); FDMemTable1->FieldDefs->Add("Name", ftString, 20, False); FDMemTable1->CreateDataSet(); // Append Data FDMemTable1->Open(); FDMemTable1->Append(); FDMemTable1->FieldByName("ID")->AsInteger = 1; FDMemTable1->FieldByName("Name")->AsString = "Jim"; FDMemTable1->Post(); // Load from another DataSet FDMemTable1->CopyDataSet(DataSet1, TFDCopyDataSetOptions() << coStructure << coRestart << coAppend);
