A time series database can be imported using fixed binding of calendar dimension.
Executing the example requires a time series database with the OBJ_RUBRICATOR identifier and the C:\Doc.xlsx file. Also, add links to the Cubes, Db, Dimensions, Dt, Metabase system assemblies. Fixed binding of the calendar is set by the following method:
Sub Main;
Var
MB: IMetabase;
CrInfo: IMetabaseObjectCreateInfo;
Obj: IMetabaseObject;
ObjDesc: IMetabaseObjectDescriptor;
Binding: ICubeMetaLoaderBinding;
Provider: IDatasetDataProvider;
RubDesc: IMetabaseObjectDescriptor;
ImportRequestDef: IImportRequestDefinition;
ImportRequestProviderParams: IImportRequestProviderParams;
ValueBinding: ICubeMetaLoaderBinding;
Parser: ICubeMetaLoaderBindingParser;
Excel: IDtExcelProvider;
Begin
MB := MetabaseClass.Active;
// Data sources for import from Excel format
Excel := New DtExcelProvider.Create;
Excel.ImexMode := DtExcelImexMode.Import;
Excel.File := "C:\Doc.xlsx";
Excel.Query := "SELECT * FROM [Sheet1$]";
Excel.HasHeader := True;
Excel.CheckFieldName := True;
// Time series database
RubDesc := Mb.ItemById("OBJ_RUBRICATOR");
Provider := (Excel As IDatasetDataProvider);
// Create an import object
CrInfo := Mb.CreateCreateInfo;
CrInfo.ClassId := MetabaseObjectClass.KE_CLASS_IMPORTREQUEST;
CrInfo.Id := "OBJ_IMPORTREQUEST";
CrInfo.Name := "Import object";
CrInfo.Permanent := True;
CrInfo.Parent := RubDesc.Bind;
ObjDesc := Mb.CreateObject(CrInfo);
Obj := ObjDesc.Edit;
// Set up source
ImportRequestDef := Obj As IImportRequestDefinition;
ImportRequestDef.SourceType := ImportRequestSourceType.Provider;
ImportRequestDef.DestinationRubricator := RubDesc.Bind As IRubricator;
// Import parameters
ImportRequestProviderParams := ImportRequestDef.ProviderParams;
ImportRequestProviderParams.Provider := Provider;
ImportRequestProviderParams.NewRevisionName := "Factors import";
ImportRequestProviderParams.ImportObjectKey := Obj.Key;
ImportRequestProviderParams.LoadType := CubeMetaLoaderLoadType.CreateAndUpdate;
Binding := ImportRequestProviderParams.Bindings.Add;
// Fixed binding of calendar dimension
Binding.FieldType := CubeMetaLoaderFieldType.ConstValue;
Binding.BindingType := CubeMetaLoaderBindingType.Calendar;
Binding.FieldValue := DateTime.Today;
Binding.CalendarOptions.Levels := DimCalendarLevelSet.Year;
ValueBinding := ImportRequestProviderParams.Bindings.Add;
ValueBinding.BindingType := CubeMetaLoaderBindingType.Value;
ValueBinding.Field := "Value";
ValueBinding.FieldType := CubeMetaLoaderFieldType.Name;
Parser := ValueBinding.Parser;
Parser.ParserType := CubeMetaLoaderParserType.FixedPosition;
Parser.StringPositionStart := 0;
Parser.StringPositionEnd := -1;
Obj.Save;
End Sub Main;
After executing the example the object of the import from Excel file C:\Doc.xlsx will be created. In this object the fixed binding of the calendar dimension will be set up.
