EntityCommand Class (System.Data.EntityClient) | Microsoft Learn

Cancels the execution of an EntityCommand.

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 EntityParameter object.

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 the current command.

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 the command and returns a data reader.

Compiles the CommandText into a command tree and passes it to the underlying store provider for execution, then builds an EntityDataReader out of the produced result set using the specified CommandBehavior.

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 command, and returns the first column of the first row in the result set. Additional 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.

Compiles the entity-level command and creates a prepared version of the command.

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

Compiles the entity-level command and returns the store command text.
