DMQueryTask Class

This class provides the properties and methods for the Data Mining Query task, which runs prediction queries based on data mining models built in Analysis Services. This class cannot be inherited.


Namespace:  Microsoft.SqlServer.Dts.Tasks.DMQueryTask
Assembly:  Microsoft.SqlServer.DMQueryTask (in Microsoft.SqlServer.DMQueryTask.dll)

public class DMQueryTask : Task, 
	IDTSBreakpointSite, IDTSSuspend, IDTSComponentPersist, IDMQueryTask

The DMQueryTask type exposes the following members.

Public methodDMQueryTaskInitializes a new instance of the DMQueryTask class.

Public propertyDebugModeA Boolean that indicates if a task should check if breakpoints are enabled.
Public propertyExecutionValueReturns a user-defined object. This field is read-only. (Overrides Task.ExecutionValue.)
Public propertyInputConnectionGets or sets the connection string to an Analysis Services project or an Analysis Services database.
Public propertyInputParametersGets or sets a collection of variables that is used in a parameterized Data Mining Extensions (DMX) query.
Public propertyModelNameGets or sets the name of the mining model on which the query is based.
Public propertyModelStructureNameGets or sets the name of the mining structure on which the query is based.
Public propertyOutputConnectionGets or sets the connection string to the OLE DB data source where the prediction query result will be stored.
Public propertyOutputTableNameGets or sets the name of the table where the results of the prediction query are written.
Public propertyOverwriteOutputTableGets or sets the Boolean value that indicates if the prediction query should overwrite content in the destination table.
Public propertyQueryBuilderQueryStringInfrastructure.
Public propertyQueryBuilderSpecificationInfrastructure.
Public propertyQueryStringGets or sets a String that contains the text that the transformation uses to create a prediction query.
Public propertyResultParametersGets or sets a collection of Integration Services variables that is used to store the DMX query results.
Public propertySuspendRequiredGets 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.
Public propertyVersion*** Member deprecated; see Remarks. ***   Returns the version of the task. This property is read-only. (Inherited from Task.)

Public methodAcceptBreakpointManagerCalled 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.
Public methodCanUpdate*** Member deprecated; see Remarks. ***   A Boolean that indicates whether the new package XML can update the old package XML. (Inherited from Task.)
Public methodEqualsDetermines whether two object instances are equal. (Inherited from DtsObject.)
Public methodExecuteRuns the task. (Overrides Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
Public methodExecuteQueryExecutes the query found in the QueryString property.
Protected methodFinalize (Inherited from Object.)
Public methodGetConnectionIDGets a String containing the ID of the connection. (Inherited from Task.)
Public methodGetConnectionNameGets a String containing the name of the connection. (Inherited from Task.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from DtsObject.)
Public methodGetType (Inherited from Object.)
Public methodInitializeTaskInitializes the properties associated with the task. This method is called by the runtime and is not used in code. (Inherited from Task.)
Public methodLoadFromXMLThis method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
Protected methodMemberwiseClone (Inherited from Object.)
Public methodResumeExecutionResumes execution of the task after pausing. The task or container is resumed by the runtime engine.
Public methodSaveToXMLThis method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.
Public methodSuspendExecutionIndicates that the executable needs to suspend. This method is called by the runtime engine.
Public methodToString (Inherited from Object.)
Public methodUpdate*** Member deprecated; see Remarks. ***   This method updates the old package XML with the new package XML if CanUpdate is set to true. (Inherited from Task.)
Public methodValidateVerifies that the component is properly configured. (Overrides Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
