Classes

OracleBFile

Represents a managed OracleBFile object designed to work with the Oracle BFILE data type. This class cannot be inherited.

OracleClientFactory

Represents a set of methods for creating instances of the Oracle provider's implementation of the data source classes.

OracleCommand

Represents an SQL statement or stored procedure to execute against a database. This class cannot be inherited.

OracleCommandBuilder

Automatically generates single-table commands used to reconcile changes made to a DataSet with the associated database. This class cannot be inherited.

OracleConnection

Represents an open connection to a database. This class cannot be inherited.

OracleConnectionStringBuilder

Provides a simple way to create and manage the contents of connection strings used by the OracleConnection class.

OracleDataAdapter

Represents a set of data commands and a connection to a database that are used to fill the DataSet and update the database. This class cannot be inherited.

OracleDataReader

Provides a way of reading a forward-only stream of data rows from a data source. This class cannot be inherited.

OracleException

The exception that is generated when a warning or error is returned by an Oracle database or the .NET Framework Data Provider for Oracle. This class cannot be inherited.

OracleInfoMessageEventArgs

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

OracleLob

Represents a large object binary (LOB) data type stored on an Oracle server. This class cannot be inherited.

OracleParameter

Represents a parameter to an OracleCommand and optionally its mapping to a DataColumn. This class cannot be inherited.

OracleParameterCollection

Represents a collection of parameters relevant to an OracleCommand as well as their respective mappings to columns in a DataSet. This class cannot be inherited.

OraclePermission

Enables the .NET Framework Data Provider for Oracle to help ensure that a user has a security level adequate to access an Oracle database.

OraclePermissionAttribute

Associates a security action with a custom security attribute.

OracleRowUpdatedEventArgs

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

OracleRowUpdatingEventArgs

Provides data for the RowUpdating event.

OracleTransaction

Represents a transaction to be made in the database.

Structs

OracleBinary

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

OracleBoolean

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

OracleDateTime

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

OracleMonthSpan

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

OracleNumber

Represents a fixed precision and scale numeric value between -10 27 -1 and 10 27 -1 to be stored in or retrieved from a database.

OracleString

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

OracleTimeSpan

Represents a time interval and corresponds to the Oracle 9i INTERVAL DAY TO SECOND data type.

Enums

OracleLobOpenMode

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

OracleType

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

Delegates

OracleInfoMessageEventHandler

Represents the method that will handle the InfoMessage event of an OracleConnection.

OracleRowUpdatedEventHandler

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

OracleRowUpdatingEventHandler

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

Remarks

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.

Note

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.
