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 := 'AvroConnection';
	FDConnection1.DriverName := 'CData.Fire.Avro';
	with FDConnection1.Params as
	    TFDPhysCDataAvroConnectionDefParams do begin

	    ...
	end;


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

	...

	

Type SQL, Get Avro


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、Avro 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 AvroData.Id, AvroData.Name, AvroData.Fax,
	  Opportunity.AccountId, Opportunity.CloseDate
	FROM AvroData
	INNER JOIN Opportunity
	  ON AvroData.Id = Opportunity.AccountId
	

集計関数

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

CRUD 処理

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