IDtOleDbProvider.ConnectionString

Syntax

ConnectionString: String;

Description

The ConnectionString property determines connection string, used for connecting to data provider.

Example

Executing the example requires that the repository contains an ETL task with the ETL identifier and an Access database file named db.mdb in the root of the C disk. There is a table named Table_1 in the database.

Sub UserProc;
Var
    MB: IMetabase;
    MObj: IMetabaseObject;
    EtlTask: IEtlTask;
    EtlProvider: IEtlPlainDataProvider;
    OleDbProvider: IDtOleDbProvider;
    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 OleDb" object
    EtlProvider := EtlTask.Create(EtlObjectType.PlainDataOleDbProvider) As IEtlPlainDataProvider;
    EtlProvider := EtlProvider.Edit;
    EtlProvider.Id := "OleDb_Provider";
    EtlProvider.Name := "Import from OleDb";
    EtlProvider.Description := "Import from OleDb";
    // Set up data provider
    OleDbProvider := EtlProvider.Provider As IDtOleDbProvider;
    OleDbProvider.ConnectionString := "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\db.mdb;Persist Security Info=False";
    OleDbProvider.Query := "Select * from Table_1";
    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(5050);
    WxProvider.Extension := WxETLProvider As IWxShapeExtension;
    // End of visual object creation
    // Save ETL task
    MObj.Save;
End Sub UserProc;

After executing the example the Import from OleDb object is created in the ETL task. This data provider extracts data from the specified table in the Access database.
