Common code samples:

Delphi / Object Pascal

[delphi] // 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]); [/delphi]

C++

[cpp] // 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);

[/cpp]
