OracleCommand Class (System.Data.OracleClient) | Microsoft Learn

Attempts to cancel the execution of an OracleCommand.

Creates a copy of this OracleCommand object.

Creates a new instance of a DbParameter object.

Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.

Creates a new instance of an OracleParameter object.

Releases all resources used by the Component.

Releases the unmanaged resources used by the Component and optionally releases the managed resources.

Determines whether the specified object is equal to the current object.

Executes the command against its connection, returning a DbDataReader that can be used to access the results.

Providers should implement this method to provide a non-default implementation for ExecuteReader overloads.

The default implementation invokes the synchronous ExecuteReader() method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellation token. Exceptions thrown by ExecuteReader will be communicated via the returned Task Exception property.

This method accepts a cancellation token that can be used to request the operation to be cancelled early. Implementations may ignore this request.

Executes an SQL statement against the Connection and returns the number of rows affected.

An asynchronous version of ExecuteNonQuery(), which executes the command against its connection object, returning the number of rows affected.

Invokes ExecuteNonQueryAsync(CancellationToken) with CancellationToken.None.

This is the asynchronous version of ExecuteNonQuery(). Providers should override with an appropriate implementation. The cancellation token may optionally be ignored.

The default implementation invokes the synchronous ExecuteNonQuery() method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellation token. Exceptions thrown by ExecuteNonQuery() will be communicated via the returned Task Exception property.

Do not invoke other methods and properties of the DbCommand object until the returned Task is complete.

Executes an SQL statement against the Connection and returns the number of rows affected.

Executes the query, and returns the first column of the first row in the result set returned by the query as an Oracle-specific data type. Extra columns or rows are ignored.

Sends the CommandText to the Connection and builds an OracleDataReader.

Sends the CommandText to the Connection, and builds an OracleDataReader using one of the CommandBehavior values.

An asynchronous version of ExecuteReader, which executes the command against its connection, returning a DbDataReader that can be used to access the results.

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken) with CancellationToken.None.

An asynchronous version of ExecuteReader, which executes the command against its connection, returning a DbDataReader that can be used to access the results.

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken).

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken).

An asynchronous version of ExecuteReader, which executes the command against its connection, returning a DbDataReader that can be used to access the results.

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken).

Executes the query, and returns the first column of the first row in the result set returned by the query as a .NET data type. Extra columns or rows are ignored.

An asynchronous version of ExecuteScalar(), which executes the command and returns the first column of the first row in the first returned result set. All other columns, rows and result sets are ignored.

Invokes ExecuteScalarAsync(CancellationToken) with CancellationToken.None.

This is the asynchronous version of ExecuteScalar(). Providers should override with an appropriate implementation. The cancellation token may optionally be ignored.

The default implementation invokes the synchronous ExecuteScalar() method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellation token. Exceptions thrown by ExecuteScalar will be communicated via the returned Task Exception property.

Do not invoke other methods and properties of the DbCommand object until the returned Task is complete.

Serves as the default hash function.

Obsolete.

Retrieves the current lifetime service object that controls the lifetime policy for this instance.

Returns an object that represents a service provided by the Component or by its Container.

Gets the Type of the current instance.

Obsolete.

Obtains a lifetime service object to control the lifetime policy for this instance.

Creates a shallow copy of the current Object.

Creates a shallow copy of the current MarshalByRefObject object.

Creates a prepared (or compiled) version of the command at the data source.

Resets the CommandTimeout property to the default value.

Returns a String containing the name of the Component, if any. This method should not be overridden.
