Propriétés

  Nom Description
Propriété publique DebugMode A Boolean that indicates if a task should check if breakpoints are enabled.
Propriété publique ExecutionValue Returns a user-defined object. This field is read-only. (remplace Task. . :: . .ExecutionValue.)
Propriété publique InputConnection Gets or sets the connection string to an Analysis Services project or an Analysis Services database.
Propriété publique InputParameters Gets or sets a collection of variables that is used in a parameterized Data Mining Extensions (DMX) query.
Propriété publique ModelName Gets or sets the name of the mining model on which the query is based.
Propriété publique ModelStructureName Gets or sets the name of the mining structure on which the query is based.
Propriété publique OutputConnection Gets or sets the connection string to the OLE DB data source where the prediction query result will be stored.
Propriété publique OutputTableName Gets or sets the name of the table where the results of the prediction query are written.
Propriété publique OverwriteOutputTable Gets or sets the Boolean value that indicates if the prediction query should overwrite content in the destination table.
Propriété publique QueryBuilderQueryString Infrastructure.
Propriété publique QueryBuilderSpecification Infrastructure.
Propriété publique QueryString Gets or sets a String that contains the text that the transformation uses to create a prediction query.
Propriété publique ResultParameters Gets or sets a collection of Integration Services variables that is used to store the DMX query results.
Propriété publique 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.
Propriété publique Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. (hérité de Task.)

Méthodes

  Nom Description
Méthode publique 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.
Méthode publique CanUpdate *** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (hérité de Task.)
Méthode publique Equals Determines whether two object instances are equal. (hérité de DtsObject.)
Méthode publique Execute Runs the task. (remplace Task. . :: . .Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
Méthode publique ExecuteQuery Executes the query found in the QueryString property.
Méthode protégée Finalize (hérité de Object.)
Méthode publique GetConnectionID Gets a String containing the ID of the connection. (hérité de Task.)
Méthode publique GetConnectionName Gets a String containing the name of the connection. (hérité de Task.)
Méthode publique GetHashCode Returns the hash code for this instance. (hérité de DtsObject.)
Méthode publique GetType (hérité de Object.)
Méthode publique InitializeTask Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (hérité de Task.)
Méthode publique LoadFromXML This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
Méthode protégée MemberwiseClone (hérité de Object.)
Méthode publique ResumeExecution Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
Méthode publique SaveToXML This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
Méthode publique SuspendExecution Indicates that the executable needs to suspend. This method is called by the runtime engine.
Méthode publique ToString (hérité de Object.)
Méthode publique Update *** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. (hérité de Task.)
Méthode publique Validate Verifies that the component is properly configured. (remplace Task. . :: . .Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)
