EntityCommand Methods

 

Namespace:   System.Data.EntityClient
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

NameDescription
System_CAPS_pubmethodCancel()

Cancels the execution of an EntityCommand.(Overrides DbCommand.Cancel().)

System_CAPS_pubmethodCreateObjRef(Type)

Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.(Inherited from MarshalByRefObject.)

System_CAPS_pubmethodCreateParameter()

Creates a new instance of an EntityParameter object.

System_CAPS_pubmethodDispose()

Releases all resources used by the Component.(Inherited from Component.)

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodExecuteNonQuery()

Executes the current command.(Overrides DbCommand.ExecuteNonQuery().)

System_CAPS_pubmethodExecuteNonQueryAsync()

An asynchronous version of ExecuteNonQuery, which executes a SQL statement against a connection object.

Invokes ExecuteNonQueryAsync with CancellationToken.None.(Inherited from DbCommand.)

System_CAPS_pubmethodExecuteNonQueryAsync(CancellationToken)

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.(Inherited from DbCommand.)

System_CAPS_pubmethodExecuteReader()

Executes the command and returns a data reader.

System_CAPS_pubmethodExecuteReader(CommandBehavior)

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.

System_CAPS_pubmethodExecuteReaderAsync()

An asynchronous version of ExecuteReader, which executes the CommandText against the Connection and returns a DbDataReader.

Invokes ExecuteDbDataReaderAsync with CancellationToken.None.(Inherited from DbCommand.)

System_CAPS_pubmethodExecuteReaderAsync(CancellationToken)

An asynchronous version of ExecuteReader, which executes the CommandText against the Connection and returns a DbDataReader. This method propagates a notification that operations should be canceled.

Invokes ExecuteDbDataReaderAsync.(Inherited from DbCommand.)

System_CAPS_pubmethodExecuteReaderAsync(CommandBehavior)

An asynchronous version of ExecuteReader, which executes the CommandText against the Connection and returns a DbDataReader.

Invokes ExecuteDbDataReaderAsync.(Inherited from DbCommand.)

System_CAPS_pubmethodExecuteReaderAsync(CommandBehavior, CancellationToken)

Invokes ExecuteDbDataReaderAsync.(Inherited from DbCommand.)

System_CAPS_pubmethodExecuteScalar()

Executes the command, and returns the first column of the first row in the result set. Additional columns or rows are ignored.(Overrides DbCommand.ExecuteScalar().)

System_CAPS_pubmethodExecuteScalarAsync()

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

Invokes ExecuteScalarAsync with CancellationToken.None.(Inherited from DbCommand.)

System_CAPS_pubmethodExecuteScalarAsync(CancellationToken)

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.(Inherited from DbCommand.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetLifetimeService()

Retrieves the current lifetime service object that controls the lifetime policy for this instance.(Inherited from MarshalByRefObject.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodInitializeLifetimeService()

Obtains a lifetime service object to control the lifetime policy for this instance.(Inherited from MarshalByRefObject.)

System_CAPS_pubmethodPrepare()

Compiles the entity-level command and creates a prepared version of the command.(Overrides DbCommand.Prepare().)

System_CAPS_pubmethodToString()

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

System_CAPS_pubmethodToTraceString()

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

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethodIDbCommand.CreateParameter()

Creates a new instance of an IDbDataParameter object.(Inherited from DbCommand.)

System_CAPS_pubinterfaceSystem_CAPS_privmethodIDbCommand.ExecuteReader()

Executes the CommandText against the Connection and builds an IDataReader.(Inherited from DbCommand.)

System_CAPS_pubinterfaceSystem_CAPS_privmethodIDbCommand.ExecuteReader(CommandBehavior)

Executes the CommandText against the Connection, and builds an IDataReader using one of the CommandBehavior values.(Inherited from DbCommand.)
