Provides data for the RowUpdated event. This class cannot be inherited.

System_CAPS_pubclassOracleRowUpdatingEventArgs

Provides data for the RowUpdating event.

System_CAPS_pubclassOracleTransaction

Represents a transaction to be made in the database.

StructureDescription
System_CAPS_pubstructureOracleBinary

Represents a variable-length stream of binary data to be stored in or retrieved from a database.

System_CAPS_pubstructureOracleBoolean

Represents the value returned from a database comparison operation between Oracle data types, and exposes methods used to perform data type conversions.

System_CAPS_pubstructureOracleDateTime

Represents date and time data ranging in value from January 1, 4712 BC to December 31, 4712 AD.

System_CAPS_pubstructureOracleMonthSpan

Represents a time interval in months and corresponds to the Oracle 9i INTERVAL YEAR TO MONTH data type.

System_CAPS_pubdelegateOracleRowUpdatedEventHandler

Represents the method that will handle the RowUpdated event of an OracleDataAdapter.

System_CAPS_pubdelegateOracleRowUpdatingEventHandler

Represents the method that will handle the RowUpdating event of an OracleDataAdapter.

EnumerationDescription
System_CAPS_pubenumOracleLobOpenMode

Specifies whether an OracleLob should be opened in read-only or read/write mode.

System_CAPS_pubenumOracleType

Specifies the data type of a field or property for use in an OracleParameter.

This types in System.Data.OracleClient are deprecated and will be removed in a future version of the .NET Framework. For more information, see Oracle and ADO.NET.

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.

System_CAPS_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.
