Query: String;
The Query property determines Visual Foxpro tables query.
Imported data is selected by means of the query.
Executing the example requires that the repository contains an ETL task with the ETL identifier and the Visual Foxpro Data.dbf table in the root of the C disk.
Sub Main;
Var
MB: IMetabase;
MObj: IMetabaseObject;
EtlTask: IEtlTask;
EtlProvider: IEtlPlainDataProvider;
VfpProvider: IDtVfpProvider;
WxProvider: IWxRectangle;
WxETLProvider: IWxETLObject;
Begin
MB := MetabaseClass.Active;
// ETL task search. Repository object with the ETL identifier
MObj := MB.ItemById("ETL").Edit;
EtlTask := MObj As IEtlTask;
// Start of data provider creation
// Create the "Import from Visual Foxpro" object
EtlProvider := EtlTask.Create(EtlObjectType.PlainDataVfpProvider) As IEtlPlainDataProvider;
EtlProvider := EtlProvider.Edit;
EtlProvider.Id := "Vfp_Provider";
EtlProvider.Name := "Import from Visual Foxpro";
EtlProvider.Description := "Import from Visual Foxpro";
// Set up data provider
VfpProvider := EtlProvider.Provider As IDtVfpProvider;
VfpProvider.Path := "c:\";
VfpProvider.Query := "Select * From Data";
EtlProvider.FillDefault;
// Save data provider
EtlProvider.Save;
// End of data provider creation
// Start of visual object creation
WxProvider := EtlTask.Workspace.CreateRectangle;
WxETLProvider := New WxETLObject.Create;
WxETLProvider.ETLObject := EtlProvider;
WxProvider.Style.TextPosition := WxTextPosition.Bottom;
WxProvider.Style.PictureMarginTop := -10;
WxProvider.PinPosition := New GxPointF.Create(50, 50);
WxProvider.Extension := WxETLProvider As IWxShapeExtension;
// End of visual object creation
// Save ETL task
MObj.Save;
End Sub Main;
After executing the example the Import from Visual Foxpro object is created in the ETL task. This data provider imports data from the Foxpro table named Data.
