• ,

• ;

• .

• :

• {Tabulation} - code #9

• {Carriage return} - code #13

• {Row transfer} - code #10

• {Carriage return}{Row transfer} - #13+#10

• Any other symbol, or a combination of symbols, optional for user.

Example

Executing the example requires that the repository contains an ETL task with the Etl identifier, and the text file Data.txt in the disk C root directory.

Sub Main;

Var

MB: IMetabase;

MObj: IMetabaseObject;

EtlTask: IEtlTask;

EtlProvider: IEtlPlainDataProvider;

TextProvider: IDtTextProvider;

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 Text object creation

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

EtlProvider := EtlProvider.Edit;

EtlProvider.Id := "Text_Provider";

EtlProvider.Name := "Import from text";

EtlProvider.Description := "Import from text";

//Set up data provider

TextProvider := EtlProvider.Provider As IDtTextProvider;

TextProvider.File := "c:\Data.txt";

TextProvider.RangeHasHeader := True;

TextProvider.RowDelimiter := #13 + #10; //Carriage return + row transfer

TextProvider.DelimitedColumnDelimiter := #9; //Tab button

TextProvider.FieldsFromFile;

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 text object is created in the ETL task. The provider imports data from the Data.txt text file. During import the Carriage return+Row transfer combination is used as a row delimiter, and Tabulation symbol - as a field delimiter. Field names are imported from the first file row.
