Oracle Data Provider for .NET Assembly

The Oracle.DataAccess.dll assembly provides two namespaces:

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.

Oracle.DataAccess.Client

Table 1-1 lists the client classes.

Table 1-1 Oracle.DataAccess.Client

Class Description
OnChangeEventHandler Delegate The OnChangedEventHandler event delegate represents the signature of the method that handles the notification.

Not Supported in a .NET Stored Procedure

OracleCommand Class An OracleCommand object represents a SQL command, a stored procedure or function, or a table name.
OracleCommandBuilder Class An OracleCommandBuilder object provides automatic SQL generation for the OracleDataAdapter when the database is updated.
OracleConnection Class An OracleConnection object represents a connection to Oracle Database.
OracleDataAdapter Class An OracleDataAdapter object represents a data provider object that communicates with the DataSet.
OracleDataReader Class An OracleDataReader object represents a forward-only, read-only, in-memory result set.
OracleDependency Class An OracleDependency class represents a dependency between an application and an Oracle database.

Not Supported in a .NET Stored Procedure

OracleError Class The OracleError object represents an error reported by an Oracle database.
OracleErrorCollection Class An OracleErrorCollection object represents a collection of OracleErrors.
OracleException Class The OracleException object represents an exception that is thrown when Oracle Data Provider for .NET encounters an error.
OracleFailoverEventArgs Class The OracleFailoverEventArgs class provides event data for the OracleConnection.Failover event.

Not Supported in a .NET Stored Procedure

OracleFailoverEventHandler Delegate The OracleFailoverEventHandler represents the signature of the method that handles the OracleConnection.Failover event.

Not Supported in a .NET Stored Procedure

OracleGlobalization Class The OracleGlobalization class is used to obtain and set the Oracle globalization settings of the session, thread, and local computer (read-only).
OracleInfoMessageEventArgs Class The OracleInfoMessageEventArgs object provides event data for the OracleConnection.InfoMessage event.
OracleInfoMessageEventHandler Delegate The OracleInfoMessageEventHandler delegate represents the signature of the method that handles the OracleConnection.InfoMessage event.
OracleNotificationEventArgs Class The OnChangedEventArgs class provides event data for a notification.
OracleNotificationRequest Class An OracleNotificationRequest class represents a notification request to be subscribed in the database.

Not Supported in a .NET Stored Procedure

OracleParameter Class An OracleParameter object represents a parameter for an OracleCommand.
OracleParameterCollection Class An OracleParameterCollection object represents a collection of OracleParameters.
OracleRowUpdatedEventArgs Class The OracleRowUpdatedEventArgs object provides event data for the OracleDataAdapter.RowUpdated event.
OracleRowUpdatedEventHandler Delegate The OracleRowUpdatedEventHandler delegate represents the signature of the method that handles the OracleDataAdapter.RowUpdated event.
OracleRowUpdatingEventArgs Class The OracleRowUpdatingEventArgs object provides event data for the OracleDataAdapter.RowUpdating event.
OracleRowUpdatingEventHandler Delegate The OracleRowUpdatingEventHandler delegate represents the signature of the method that handles the OracleDataAdapter.RowUpdating event.
OracleTransaction Class An OracleTransaction object represents a local transaction.

Not Supported in a .NET Stored Procedure

OracleXmlQueryProperties Class An OracleXmlQueryProperties object represents the XML properties used by the OracleCommand class when the XmlCommandType property is Query.
OracleXmlSaveProperties Class An OracleXmlSaveProperties object represents the XML properties used by the OracleCommand class when the XmlCommandType property is Insert, Update, or Delete.

Oracle.DataAccess.Client Enumerations

Table 1-2 lists the client enumerations.

Table 1-2 Oracle.DataAccess.Client Enumerations

Enumeration Description
FailoverEvent Enumeration FailoverEvent enumerated values are used to specify the state of the failover.

Not Supported in a .NET Stored Procedure

FailoverReturnCode Enumeration FailoverReturnCode enumerated values are passed back by the application to the ODP.NET provider to request a retry in case of a failover error, or to continue in case of a successful failover.

Not Supported in a .NET Stored Procedure

FailoverType Enumeration FailoverType enumerated values are used to indicate the type of failover event that was raised.

Not Supported in a .NET Stored Procedure

OracleCollectionType Enumeration OracleCollectionType enumerated values specify whether or not the OracleParameter object represents a collection, and if so, specifies the collection type.

Not Supported in a .NET Stored Procedure

OracleDbType Enumeration OracleDbType enumerated values are used to explicitly specify the OracleDbType of an OracleParameter.
OracleNotificationInfo Enumeration OracleNotificationInfo enumerated values specify the database event that causes the notification.

Not Supported in a .NET Stored Procedure

OracleNotificationSource Enumeration OracleNotificationSource enumerated values specify the different sources that cause notification.

Not Supported in a .NET Stored Procedure

OracleNotificationType Enumeration OracleNotificationType enumerated values specify the different types that cause the notification.

Not Supported in a .NET Stored Procedure

OracleParameterStatus Enumeration The OracleParameterStatus enumeration type indicates whether a NULL value is fetched from a column, or truncation has occurred during the fetch, or a NULL value is to be inserted into a database column.
OracleXmlCommandType Enumeration The OracleXmlCommandType enumeration specifies the values that are allowed for the OracleXmlCommandType property of the OracleCommand class.

Oracle.DataAccess.Types Namespace

The Oracle.DataAccess.Types namespace provides classes, structures, and exceptions for Oracle native types that can be used with Oracle Data Provider for .NET.

Oracle.DataAccess.Types Structures

Table 1-3 lists the type structures.

Table 1-3 Oracle.DataAccess.Types Structures

Structure Description
OracleBinary Structure The OracleBinary structure represents a variable-length stream of binary data.
OracleDate Structure The OracleDate structure represents the Oracle DATE datatype.
OracleDecimal Structure The OracleDecimal structure represents an Oracle NUMBER in the database or any Oracle numeric value.
OracleIntervalDS Structure The OracleIntervalDS structure represents the Oracle INTERVAL DAY TO SECOND datatype.
OracleIntervalYM Structure The OracleIntervalYM structure represents the Oracle INTERVAL YEAR TO MONTH datatype.
OracleString Structure The OracleString structure represents a variable-length stream of characters.
OracleTimeStamp Structure The OracleTimeStamp structure represents the Oracle TimeStamp datatype.
OracleTimeStampLTZ Structure The OracleTimeStampLTZ structure represents the Oracle TIMESTAMP WITH LOCAL TIME ZONE datatype.
OracleTimeStampTZ Structure The OracleTimeStampTZ structure represents the Oracle TIMESTAMP WITH TIME ZONE datatype.

Oracle.DataAccess.Types Exceptions

Type Exceptions are thrown only by ODP.NET type structures. Table 1-4 lists the type exceptions.
