IDtOleDbConsumer.ConnectionString

Syntax

ConnectionString: String;

Description

The ConnectionString property determines a connection string that is used to connect to data consumer.

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;
    EtlConsumer: IEtlPlainDataConsumer;
    OleDbConsumer: IDtOleDbConsumer;
    WxConsumer: IWxRectangle;
    WxETLConsumer: 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 creating a data consumer
    // Create the "Export to OleDb" object
    EtlConsumer := EtlTask.Create(EtlObjectType.PlainDataOleDbConsumer) As IEtlPlainDataConsumer;
    EtlConsumer := EtlConsumer.Edit;
    EtlConsumer.Id := "OleDb_Consumer";
    EtlConsumer.Name := "Export to OleDb";
    EtlConsumer.Description := "Export to OleDb";
    // Set up data consumer
    OleDbConsumer := EtlConsumer.Consumer As IDtOleDbConsumer;
    OleDbConsumer.ConnectionString := "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\db.mdb;Persist Security Info=False";
    OleDbConsumer.Table := "Table_1";
    EtlConsumer.FillDefault;
    // Save data consumer
    EtlConsumer.Save;
    // End of creating a data consumer
    // Start of visual object creation
    WxConsumer := EtlTask.Workspace.CreateRectangle;
    WxETLConsumer := New WxETLObject.Create;
    WxETLConsumer.ETLObject := EtlConsumer;
    WxConsumer.Style.TextPosition := WxTextPosition.Bottom;
    WxConsumer.Style.PictureMarginTop := -10;
    WxConsumer.PinPosition := New GxPointF.Create(5050);
    WxConsumer.Extension := WxETLConsumer As IWxShapeExtension;
    // End of visual object creation
    // Save ETL task
    MObj.Save;
End Sub UserProc;

After executing the example in the task ETL the object Export through OleDb is created. This data consumer exports data to the specified table named in the database.
