FireDAC Components

あらゆるデータソースにRDB と同感覚で連携が可能に



標準FireDAC Components


MySQL やSQL Server のようなRDBMS への接続と同感覚。 TDFManager、TDFConnection、TDFQueryUse といった標準FireDAC components として。


	FDConnection1.Name := 'PrestoConnection';
	FDConnection1.DriverName := 'CData.Fire.Presto';
	with FDConnection1.Params as
	    TFDPhysCDataPrestoConnectionDefParams do begin

	    ...
	end;


	FDConnection1.Connected := true;
	FDQuery1.Active := true;
	FDQuery1.Open('select * from Tables');

	...

Type SQL, Get Presto


データ連携アプリケーションを開発する最適解。 RDBMS の扱いと同感覚で、Presto への連携を、標準SQL で実装可能。JOIN、更新系、集計など多彩なSQL サポート。

SELECT WITH INNER JOIN

	SELECT Tables.Id, Tables.Name, Tables.Fax,
	  Opportunity.AccountId, Opportunity.CloseDate
	FROM Tables
	INNER JOIN Opportunity
	  ON Tables.Id = Opportunity.AccountId

集計関数

	SELECT Name, AVG(AnnualRevenue) FROM Tables GROUP BY Name

CRUD 処理

	UPDATE Tables SET Name='John' WHERE Id = @myId
