System.Data.OracleClient Namespace

The System.Data.OracleClient namespace is the .NET Framework Data Provider for Oracle.

The .NET Framework Data Provider for Oracle describes a collection of classes for accessing an Oracle data source in the managed space. Using the OracleDataAdapter class, you can fill a memory-resident DataSet, query it, and use it to update the data source.

For additional information about how to use this namespace, see the OracleDataReader, OracleCommand, and OracleConnection classes.

NoteNote:

For conceptual information about using this namespace when programming with the .NET Framework, see Oracle and ADO.NET.

The .NET Framework Data Provider for Oracle supports a number of Oracle data types, including the BFILE, LOB, and REF CURSOR data types. For information about using Oracle data types in parameters, see OracleType.
