Eigenschaften

  Name Beschreibung
Öffentliche Eigenschaft BatchSize Gets or sets the number of rows in each batch.
Öffentliche Eigenschaft CheckConstraints Gets or sets a Boolean that indicates if you want to enforce table and column check constraints.
Öffentliche Eigenschaft CodePage Gets or sets the code page of the data in the data file.
Öffentliche Eigenschaft DataFileType Gets or sets a value from the DTSBulkInsert_DataFileType enumeration that indicates the data-type value to use in the load operation.
Öffentliche Eigenschaft DebugMode Gets or sets a Boolean that indicates whether a task should determine whether breakpoints are enabled.
Öffentliche Eigenschaft DestinationConnection Gets or sets the name of the destination connection object.
Öffentliche Eigenschaft DestinationTableName Gets or sets the name of the destination table or view.
Öffentliche Eigenschaft ExecutionValue Returns a user-defined object. This field is read-only. (Geerbt von Task.)
Öffentliche Eigenschaft FieldTerminator Gets or sets the field terminator for use in char and widechar data files.
Öffentliche Eigenschaft FireTriggers Gets or sets a Boolean that indicates whether the insert triggers should be executed on the table during the operation.
Öffentliche Eigenschaft FirstRow Gets or sets the first row from which to start copying.
Öffentliche Eigenschaft FormatFile Gets or sets the full path of a format file.
Öffentliche Eigenschaft KeepIdentity Gets or sets a Boolean that specifies how identity value or values in the imported data file are used for the identity column
Öffentliche Eigenschaft KeepNulls Gets or sets a Boolean that indicates whether empty columns should retain a nullein NULL-Verweis (Nothing in Visual Basic) value during the bulk load operation, or insert default values into the columns.
Öffentliche Eigenschaft LastRow Gets or sets the number of the last row to copy.
Öffentliche Eigenschaft MaximumErrors Gets or sets the maximum number of errors that can occur before the bulk insert operation fails.
Öffentliche Eigenschaft RowTerminator Gets or sets the row terminator for use in char and widechar data files.
Öffentliche Eigenschaft SortedData Gets or sets the Order by clause in the bulk insert statement
Öffentliche Eigenschaft SourceConnection Gets or sets the name of the source connection object.
Öffentliche Eigenschaft SqlStatement Gets a String array that contains the Transact-SQL statement to run.
Öffentliche Eigenschaft SuspendRequired Gets or sets a Boolean that indicates whether tasks should suspend when they encounter a breakpoint. This value is set by the runtime engine for tasks and containers when a breakpoint is encountered.
Öffentliche Eigenschaft TableLock Gets or sets a Boolean that indicates whether the table is locked during the bulk insert operation.
Öffentliche Eigenschaft UseFormatFile Gets or sets a Boolean that indicates whether the Bulk Insert task uses a format file.
Öffentliche Eigenschaft Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. (Geerbt von Task.)

Methoden

  Name Beschreibung
Öffentliche Methode 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.
Öffentliche Methode CanUpdate *** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (Geerbt von Task.)
Öffentliche Methode Equals Determines whether two object instances are equal. (Geerbt von DtsObject.)
Öffentliche Methode Execute Runs the Bulk Insert task. (Überschreibt Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
Öffentliche Methode GetConnectionID Gets a String containing the ID of the connection. (Geerbt von Task.)
Öffentliche Methode GetConnectionName Gets a String containing the name of the connection. (Geerbt von Task.)
Öffentliche Methode GetHashCode Returns the hash code for this instance. (Geerbt von DtsObject.)
Öffentliche Methode GetType (Geerbt von Object.)
Öffentliche Methode InitializeTask Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (Überschreibt Task.InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker).)
Öffentliche Methode LoadFromXML This method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
Öffentliche Methode ResumeExecution Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
Öffentliche Methode SaveToXML This method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.
Öffentliche Methode SuspendExecution Indicates that the executable needs to suspend. This method is called by the runtime engine.
Öffentliche Methode ToString (Geerbt von Object.)
Öffentliche Methode Update *** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. (Geerbt von Task.)
Öffentliche Methode Validate Verifies that the Bulk Insert task component is correctly configured. (Überschreibt Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)
