Открытое свойство BatchSize Gets or sets the number of rows in each batch.
Открытое свойство CheckConstraints Gets or sets a Boolean that indicates if you want to enforce table and column check constraints.
Открытое свойство CodePage Gets or sets the code page of the data in the data file.
Открытое свойство DataFileType Gets or sets a value from the DTSBulkInsert_DataFileType enumeration that indicates the data-type value to use in the load operation.
Открытое свойство DebugMode Gets or sets a Boolean that indicates whether a task should determine whether breakpoints are enabled.
Открытое свойство DestinationConnection Gets or sets the name of the destination connection object.
Открытое свойство DestinationTableName Gets or sets the name of the destination table or view.
Открытое свойство ExecutionValue Returns a user-defined object. This field is read-only. (Производный от Task.)
Открытое свойство FieldTerminator Gets or sets the field terminator for use in char and widechar data files.
Открытое свойство FireTriggers Gets or sets a Boolean that indicates whether the insert triggers should be executed on the table during the operation.
Открытое свойство FirstRow Gets or sets the first row from which to start copying.
Открытое свойство FormatFile Gets or sets the full path of a format file.
Открытое свойство KeepIdentity Gets or sets a Boolean that specifies how identity value or values in the imported data file are used for the identity column
Открытое свойство KeepNulls Gets or sets a Boolean that indicates whether empty columns should retain a nullNothingnullptrunitпустая ссылка (Nothing в Visual Basic) value during the bulk load operation, or insert default values into the columns.
Открытое свойство LastRow Gets or sets the number of the last row to copy.

Методы

  Имя Описание
Открытый метод AcceptBreakpointManager Called by the run-time engine when a task or container is created, and is passed a BreakpointManager to enable the task to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code.
Открытый метод CanUpdate *** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (Производный от Task.)
Открытый метод Equals Determines whether two object instances are equal. (Производный от DtsObject.)
Открытый метод Execute Runs the Bulk Insert task. (Переопределяет Task. . :: . .Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
Защищенный метод Finalize (Производный от Object.)
Открытый метод GetConnectionID Gets a String containing the ID of the connection. (Производный от Task.)
Открытый метод GetConnectionName Gets a String containing the name of the connection. (Производный от Task.)
Открытый метод GetHashCode Returns the hash code for this instance. (Производный от DtsObject.)
Открытый метод GetType (Производный от Object.)
Открытый метод InitializeTask Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (Переопределяет Task. . :: . .InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker).)
Открытый метод LoadFromXML This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
Защищенный метод MemberwiseClone (Производный от Object.)
Открытый метод ResumeExecution Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
Открытый метод SaveToXML This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
Открытый метод SuspendExecution Indicates that the executable needs to suspend. This method is called by the runtime engine.
Открытый метод ToString (Производный от Object.)
Открытый метод Update *** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. (Производный от Task.)
Открытый метод Validate Verifies that the Bulk Insert task component is correctly configured. (Переопределяет Task. . :: . .Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)

Безопасность многопоточности

Любые открытые статический (Shared в Visual Basic) элементы этого типа потокобезопасны. Потокобезопасность с элементами экземпляров не гарантируется.
