Konstruktoren

	Name	Beschreibung
	DMQueryTask	Initializes a new instance of the DMQueryTask class.

Zum Anfang

Eigenschaften

	Name	Beschreibung
	DebugMode	A Boolean that indicates if a task should check if breakpoints are enabled.
	ExecutionValue	Returns a user-defined object. This field is read-only. (Überschreibt 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	Infrastruktur
	QueryBuilderSpecification	Infrastruktur
	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 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. (Geerbt von Task.)

Methoden

	Name	Beschreibung
	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. (Geerbt von Task.)
	Equals	Determines whether two object instances are equal. (Geerbt von DtsObject.)
	Execute	Runs the task. (Überschreibt Task. . :: . .Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
	ExecuteQuery	Executes the query found in the QueryString property.
	Finalize	(Geerbt von Object.)
	GetConnectionID	Gets a String containing the ID of the connection. (Geerbt von Task.)
	GetConnectionName	Gets a String containing the name of the connection. (Geerbt von Task.)
	GetHashCode	Returns the hash code for this instance. (Geerbt von DtsObject.)
	GetType	(Geerbt von Object.)
	InitializeTask	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (Geerbt von Task.)
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
	MemberwiseClone	(Geerbt von Object.)
	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. To save 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	(Geerbt von Object.)
	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.)
	Validate	Verifies that the component is properly configured. (Überschreibt Task. . :: . .Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)
