IDtRdsProvider.Dataset

Syntax

Description

The Dataset property determines an MDM dictionary that is used as a data provider.

Example

Executing the example requires that the repository contains an ETL task with the ETL_Task identifier and an MDM dictionary with the RDS_DICT identifier.

Add links to the Andy, Db, Drawing, Dt, Etl, Metabase system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    ETLTask: IEtlTask;
    EtlProvider: IEtlPlainDataProvider;
    DtRds: IDtRdsProvider;
Begin
    MB := MetabaseClass.Active;
    ETLTask := MB.ItemById("ETL_Task").Edit As IEtlTask;
    //Create a new data provider - MDM dictionary
    EtlProvider := ETLTask.Create(EtlObjectType.PlainDataRdsProvider) As IEtlPlainDataProvider;
    EtlProvider := EtlProvider.Edit;
    EtlProvider.Id := "RDS_Provider";
    EtlProvider.Name := "Data provider - MDM dictionary";
    //Create a visual source object
    CreateWX(ETLTask, EtlProvider, 0, 0);
    //Set up source
    DtRds := EtlProvider.Provider As IDtRdsProvider;
    DtRds.Dataset := Mb.ItemById("RDS_DICT").Bind As IDatasetModel;
    //Save source
    EtlProvider.Save;
    //Save task
    (ETLTask As IMetabaseObject).Save;
End Sub UserProc;

//Create a visual object
Sub CreateWX(ETLTask: IEtlTask; ETLObject: IEtlObject; XPosition: Integer; YPosition: Integer);
Var
    WxRect: IWxRectangle;
    WxETLObj: IWxEtlObject;
Begin
    WxRect := ETLTask.Workspace.CreateRectangle;
    WxRect.Id := ETLObject.Id;
    WxETLObj := New WxEtlObject.Create;
    WxETLObj.EtlObject := ETLObject;
    WxRect.Style.TextPosition := WxTextPosition.Bottom;
    WxRect.Style.PictureMarginTop := -10;
    WxRect.PinPosition := New GxPointF.Create(XPosition, YPosition);
    WxRect.Extension := WxETLObj As IWxShapeExtension;
End Sub CreateWX;

After executing the example, a new data provider is created in the ETL task that is connected with the specified MDM dictionary.
