Constructors

DMQueryTask()

Initializes a new instance of the DMQueryTask class.

Properties

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.

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

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

Gets or sets the information about the state of the MicrosoftSQL ServerIntegration 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.

TargetServerVersion (Inherited from Task)
Version

*** Member deprecated; see Remarks. ***   Returns the version of the task. This property is read-only.

(Inherited from Task)

Methods

AcceptBreakpointManager(BreakpointManager)

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(String)

*** Member deprecated; see Remarks. ***   A Boolean that indicates whether the new package XML can update the old package XML.

(Inherited from Task)
Equals(Object)

Determines whether two object instances are equal.

(Inherited from DtsObject)
Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object)

Runs the task.

ExecuteQuery(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object)

Executes the query found in the QueryString property.

GetConnectionID(Connections, String)

Gets a String containing the ID of the connection.

(Inherited from Task)
GetConnectionName(Connections, String)

Gets a String containing the name of the connection.

(Inherited from Task)
GetHashCode()

Returns the hash code for this instance.

(Inherited from DtsObject)
InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker)

Initializes the properties associated with the task. This method is called by the runtime and is not used in code.

(Inherited from Task)
LoadFromXML(XmlElement, IDTSInfoEvents)

This method is not callable by your application code. Loads a package saved as .xml, use the LoadPackage(String, IDTSEvents) method.

ResumeExecution()

Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.

SaveToXML(XmlDocument, IDTSInfoEvents)

This method is not callable by your application code. Saves a package as .xml, use the SaveToXml(String, Package, IDTSEvents) method.

SuspendExecution()

Indicates that the executable needs to suspend. This method is called by the runtime engine.

Update(String)

*** Member deprecated; see Remarks. ***   This method updates the old package XML with the new package XML if CanUpdate(String) is set to true.

(Inherited from Task)
Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging)

Verifies that the component is properly configured.
