Propiedad pública ExecutionValue Gets a user-defined object. This field is read-only. (Invalida Task.ExecutionValue.)
Propiedad pública InputConnection Gets or sets the connection string to an Analysis Services project or an Analysis Services database.
Propiedad pública InputParameters Gets or sets a collection of variables that is used in a parameterized Data Mining Extensions (DMX) query.
Propiedad pública ModelName Gets or sets the name of the mining model on which the query is based.
Propiedad pública ModelStructureName Gets or sets the name of the mining structure on which the query is based.
Propiedad pública OutputConnection Gets or sets the connection string to the OLE DB data source where the prediction query result will be stored.
Propiedad pública OutputTableName Gets or sets the name of the table where the results of the prediction query are written.
Propiedad pública OverwriteOutputTable Gets or sets the Boolean value that indicates if the prediction query should overwrite content in the destination table.
Propiedad pública QueryBuilderQueryString Infraestructura. 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.
Propiedad pública QueryBuilderSpecification Infraestructura. 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.
Propiedad pública QueryString Gets or sets a String that contains the text that the transformation uses to create a prediction query.
Propiedad pública ResultParameters Gets or sets a collection of Integration Services variables that is used to store the DMX query results.
Propiedad pública 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.
