ConnectionString: String;
The ConnectionString property determines a connection string that is used to connect to data consumer.
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(50, 50);
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.
