procedure TForm1.FormCreate(Sender: TObject);
var
  List: TStrings;
  V: Variant;
begin
  FDConnection1.Open(‘DriverID=SQLite; Database=C:\Temp\FDDemo.sdb‘);

  List := TStringList.Create;

  FDConnection1.GetInfoReport(List);
  Memo1.Clear;
  Memo1.Lines.Add(‘==> 获取连接信息:‘);
  Memo1.Lines.AddStrings(List);

  FDConnection1.GetTableNames(‘‘, ‘‘, ‘‘, List);
  Memo1.Lines.Add(#13#10‘==> 获取数据库中的表名列表:‘);
  Memo1.Lines.AddStrings(List);

  FDConnection1.GetTableNames(‘‘, ‘‘, ‘‘, List, [], [tkView]);
  Memo1.Lines.Add(#13#10‘==> 获取数据库中的查询名列表:‘);
  Memo1.Lines.AddStrings(List);

  FDConnection1.GetFieldNames(‘‘, ‘‘, ‘Orders‘, ‘‘, List);
  Memo1.Lines.Add(#13#10‘==> 获取 Orders 表中的字段名列表:‘);
  Memo1.Lines.AddStrings(List);

  V := FDConnection1.ConnectionMetaDataIntf.GetTables([], [tkTable], ‘‘, ‘‘, ‘‘).Rows[0].GetData(0);
  Memo1.Lines.Add(#13#10‘==> 获取第一个表中第一列的第一个数据:‘);
  Memo1.Lines.Add(V);

  List.Free;
