Propriedades

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

Métodos

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