.gif "Propriété publique") |
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. (remplace 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 | Infrastructure. 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 | Infrastructure. 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. (hérité de Task.) |

Méthodes
| Nom | Description | |
|---|---|---|
|
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. (hérité de Task.) |
|
Equals | Determines whether two object instances are equal. (hérité de DtsObject.) |
|
Execute | Runs the task. (remplace Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).) |
|
ExecuteQuery | Executes the query found in the QueryString property. |

Finalize | (hérité de Object.) |
|
GetConnectionID | Gets a String containing the ID of the connection. (hérité de Task.) |
|
GetConnectionName | Gets a String containing the name of the connection. (hérité de Task.) |
|
GetHashCode | Returns the hash code for this instance. (hérité de DtsObject.) |
|
GetType | (hérité de Object.) |
|
InitializeTask | Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (hérité de Task.) |
|
LoadFromXML | This method is not callable by your application code. Loads a package saved as .xml, use the Application.LoadPackage method. |
|
MemberwiseClone | (hérité de 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. 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 | (hérité de Object.) |
|
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.) |
|
Validate | Verifies that the component is properly configured. (remplace Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).) |
