IDtWebProvider.TableAttributeName

Syntax

TableAttributeName: String;

Description

The TableAttributeName property determines name of the table attribute, data of which has to be imported.

Comments

The attribute is searched in the <Table> tag.

It is used with the TableAttributeValue property.

The property is relevant is the TableIdentificationType property is set to DtWebTableIdentificationType.ByAttribute.

Example

Executing the example requires that the repository contains an ETL task with the Etl identifier, and the HTML file Data.html in the disk C root directory. There is an attribute NameTable in the table code in the <Table> tag.

Sub Main;

Var

MB: IMetabase;

MObj: IMetabaseObject;

EtlTask: IEtlTask;

EtlProvider: IEtlPlainDataProvider;

WebProvider: IDtWebProvider;

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 Web object creation

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

EtlProvider := EtlProvider.Edit;

EtlProvider.Id := "Web_Provider";

EtlProvider.Name := "Import from Web";

EtlProvider.Description := "Import from Web";

//Set up data provider

WebProvider := EtlProvider.Provider As IDtWebProvider;

WebProvider.HasHeader := True;

WebProvider.TableIdentificationType := DtWebTableIdentificationType.ByAttribute;

WebProvider.TableAttributeName := "NameTable";

WebProvider.TableAttributeValue := "Two_Table";

WebProvider.Url := "c:\Data.html";

EtlProvider.FillDefault;

//Save provider

EtlProvider.Save;

//End of source 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 Web object is created in the ETL task. The provider imports data from the Data.html HTML file. The imported table is searched by values of the NameTable attribute. Field names are imported from the first table row.
