OData FireDAC Component を使えば、Delphi & C++ Builder アプリケーションからOData servicesに簡単に連携できます。 Easy-to-use OData client (consumer) enables developers to build Delphi & C++Builder Apps that easily communicate with OData services.
機能紹介
- Seamlessly maps SQL-92 queries to OData requests
- Compatible with OData version 2.0, 3.0, and 4.0
- Utilizes navigation properties to build a relational model of OData APIs
- Connect to live OData data, for real-time data access
- Full support for data aggregation and complex JOINs in SQL queries
- Secure connectivity through modern cryptography, including TLS 1.2, SHA-256, ECC, etc.
Specifications
- Native FireDAC Components for OData seamlessly integrate with RAD Studio
- Comprehensive support for CRUD (Create, Read, Update, & Delete)
- Full Unicode support for data, parameter, & metadata
- Support for 32-bit & 64-bit operating systems

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