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 := 'JSONConnection';
FDConnection1.DriverName := 'CData.Fire.JSON';
with FDConnection1.Params as
TFDPhysCDataJSONConnectionDefParams do begin
...
end;
FDConnection1.Connected := true;
FDQuery1.Active := true;
FDQuery1.Open('select * from JSONService');
...
Type SQL, Get JSON
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、JSON 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 JSONService.Id, JSONService.Name, JSONService.Fax, Opportunity.AccountId, Opportunity.CloseDate FROM JSONService INNER JOIN Opportunity ON JSONService.Id = Opportunity.AccountId
集計関数
SELECT Name, AVG(AnnualRevenue) FROM JSONService GROUP BY Name
CRUD 処理
UPDATE JSONService SET Name='John' WHERE Id = @myId
