Create a dbexpress-connection at runtime

{ The normal way for Delphi and Kylix is just to check dbExpress, put a TSQLConnection on a form then double-click the TSQLConnection to display the Connection Editor and set parameter values (database path, connection name etc.) to indicate the settings. But in our example, all goes by runtime (path and login) with dbExpress we don't need an alias or the BDE either. } procedure TVCLScanner.PostUser(const Email, FirstName, LastName: WideString); var Connection: TSQLConnection; DataSet: TSQLDataSet; begin Connection := TSQLConnection.Create(nil); with Connection do begin ConnectionName := 'VCLScanner'; DriverName := 'INTERBASE'; LibraryName := 'dbexpint.dll'; VendorLib := 'GDS32.DLL'; GetDriverFunc := 'getSQLDriverINTERBASE'; Params.Add('User_Name=SYSDBA'); Params.Add('Password=masterkey'); Params.Add('Database=milo2:D:\frank\webservices\umlbank.gdb'); LoginPrompt := False; Open; end; DataSet := TSQLDataSet.Create(nil); with DataSet do begin SQLConnection := Connection; CommandText := Format('INSERT INTO kings VALUES("%s","%s","%s")', [Email, FirstN, LastN]); try ExecSQL; except end; end; Connection.Close; DataSet.Free; Connection.Free; end;
