Connecting from RAD Studio

The CData FireDAC Components for OData implement the standard FireDAC classes and integrate OData into RAD Studio wizards. You can access the components from the RAD Studio Tool Palette and use the components alongside standard FireDAC classes like TFDQuery, TFDManager, and TFDConnection.

Connecting from OData

See Establishing a Connection to connect with the Data Explorer and FireDAC Connection Editor wizards.

RAD Studio Version Support

RAD Studio 10.4 (Sydney) and above are supported.

OData Version Support

The component is a standard OData consumer that can read and write to OData 2.0, 3.0, and 4.0 services. The major authentication schemes are supported, including HTTP Basic, Digest, and NTLM, as well as SSL/TLS. The component also facilitates connecting to data sources that use the OAuth authentication standard.

Dependencies

CData FireDAC components require the 2010 version of the VC++ (x86/x64) redistributable package that matches the bitness of RAD Studio being used. You can download this from Microsoft:

2010 VC++ Redistributable package download Note: The appropriate VC++ redistributable package requires distribution with the deployed application.
