属性

	名称	说明
	DebugMode	Gets or sets the Boolean value that indicates if a task should check if breakpoints are enabled.
	ExecutionValue	Gets a user-defined object. This field is read-only. （覆盖 Task.ExecutionValue。）
	InputConnection	Gets or sets the connection string to an Analysis Services project or an Analysis Services database.
	InputParameters	Gets or sets a collection of variables that is used in a parameterized Data Mining Extensions (DMX) query.
	ModelName	Gets or sets the name of the mining model on which the query is based.
	ModelStructureName	Gets or sets the name of the mining structure on which the query is based.
	OutputConnection	Gets or sets the connection string to the OLE DB data source where the prediction query result will be stored.
	OutputTableName	Gets or sets the name of the table where the results of the prediction query are written.
	OverwriteOutputTable	Gets or sets the Boolean value that indicates if the prediction query should overwrite content in the destination table.
	QueryBuilderQueryString	基础结构。Gets or sets a string that specifies a data mining query that appears in the UI for data mining as the initial query string, which the user can the modify.
	QueryBuilderSpecification	基础结构。Gets or sets the information about the state of the Microsoft SQL Server Integration Services UI between sessions so that editing sessions can start from where a previous session finished.
	QueryString	Gets or sets a String that contains the text that the transformation uses to create a prediction query.
	ResultParameters	Gets or sets a collection of Integration Services variables that is used to store the DMX query results.
	SuspendRequired	Gets or sets a Boolean value that indicates if 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.
	Version	*** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. （从 Task 继承。）

方法

	名称	说明
	AcceptBreakpointManager	Called by the run-time engine when a task or container is created, and is passed a BreakpointManager manager to allow the task to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code.
	CanUpdate	*** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. （从 Task 继承。）
	Equals	Determines whether two object instances are equal. （从 DtsObject 继承。）
	Execute	Runs the task. （覆盖 Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object)。）
	ExecuteQuery	Executes the query found in the QueryString property.
	Finalize	（从 Object 继承。）
	GetConnectionID	Gets a String containing the ID of the connection. （从 Task 继承。）
	GetConnectionName	Gets a String containing the name of the connection. （从 Task 继承。）
	GetHashCode	Returns the hash code for this instance. （从 DtsObject 继承。）
	GetType	（从 Object 继承。）
	InitializeTask	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. （从 Task 继承。）
	LoadFromXML	This method is not callable by your application code. Loads a package saved as .xml, use the Application.LoadPackage method.
	MemberwiseClone	（从 Object 继承。）
	ResumeExecution	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	This method is not callable by your application code. Saves a package as .xml, use the Application.SaveToXml method.
	SuspendExecution	Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	（从 Object 继承。）
	Update	*** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. （从 Task 继承。）
	Validate	Verifies that the component is properly configured. （覆盖 Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging)。）
