IDtParadoxProvider.Query

Syntax

Query: String;

Description

The Query property determines tables query, stored by specified path. Imported data is selected by means of the query.

Example

Executing the example requires that the repository contains an ETL task with the Etl identifier, and the Paradox table Table_1.Db in the disk C root directory.

Sub Main;

Var

MB: IMetabase;

MObj: IMetabaseObject;

EtlTask: IEtlTask;

EtlProvider: IEtlPlainDataProvider;

ParadoxProvider: IDtParadoxProvider;

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 the provider creation

//The Import From Paradox object creation

EtlProvider := EtlTask.Create(EtlObjectType.PlainDataParadoxProvider) As IEtlPlainDataProvider;

EtlProvider := EtlProvider.Edit;

EtlProvider.Id := "Paradox_Provider";

EtlProvider.Name := "Import from Paradox";

EtlProvider.Description := "Import from Paradox";

//Set up data provider

ParadoxProvider := EtlProvider.Provider As IDtParadoxProvider;

ParadoxProvider.DriverVersion := "Paradox 7.X";

ParadoxProvider.Path := "c:\";

ParadoxProvider.Query := "Select * from Table_1";

EtlProvider.FillDefault;

//Save provider

EtlProvider.Save;

//End of 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 Paradox object is created in the ETL task. The source imports data from the Base_1.Dbf table. During connection the Paradox 7.X drivers are used.
