Oracle Data Provider for .NET Assembly

The Oracle.DataAccess.dll assembly provides two namespaces:

The Oracle.DataAccess.Client namespace contains ODP.NET classes and enumerations for the client-side provider.
The Oracle.DataAccess.Types namespace contains the Oracle Data Provider for .NET data types (ODP.NET Types).

Oracle.DataAccess.Client Namespace

The Oracle.DataAccess.Client namespace contains implementations of core ADO.NET classes and enumerations for ODP.NET, as well as ODP.NET specific classes.

The following tables list ODP.NET classes, enumerations, and types that are supported by the Oracle.DataAccess.Client namespace. The tables also indicated which classes are not supported in .NET stored procedures.
