ICubeMetaExporter.Bindings

Syntax

Description

The Bindings property determines a binding of time series database attributes to data consumer fields.

Example

Executing the example requires a time series database with the OBJ_RUBRICATOR identifier. This database must include the COUNTRIES attribute. Also add links to the Cubes, Dal, Dimensions, Dt, Metabase system assemblies.

Sub UserProc;
Var
    TextConsumer: IDtTextConsumer;
    MB: IMetabase;
    Exporter: ICubeMetaExporter;
    Binding: ICubeMetaExporterBinding;
    Filter: ICubeMetaExporterFilter;
    FilterValues: Array;
Begin
// Data successor to export to the textual format
    TextConsumer := New DtTextConsumer.Create;
    TextConsumer.File := "C:\result_meta_exp.txt";
    TextConsumer.FormatType := DtTextFormatType.Delimited;
    TextConsumer.DelimitedColumnDelimiter := ";";
    TextConsumer.DelimitedTextQualifier := """";
    TextConsumer.Encoding := "WIN";
    TextConsumer.WriteHeader := True;
// Export parameters
    Exporter := New CubeMetaExporterClass.Create;
    MB := MetabaseClass.Active;
    Exporter.Rubricator := MB.ItemById("OBJ_RUBRICATOR").Bind As IRubricator;
    Exporter.Consumer := TextConsumer As IDtConsumer;
// Attribute binding COUNTRIES
    Binding := Exporter.Bindings.Add;
    Binding.FieldName := "CountryKey";
    Binding.DataType := DbDataType.Integer;
    Binding.BindingType := CubeMetaExporterBindingType.Attribute;
    Binding.Attribute := "COUNTRIES";
    Binding.KeyField := "KEY";
// Calendar binding
    Binding := Exporter.Bindings.Add;
    Binding.FieldName := "Year";
    Binding.DataType := DbDataType.String;
    Binding.BindingType := CubeMetaExporterBindingType.Calendar;
    Binding.DateFormat := "$Year$";
    Binding.ValueFieldName := "Value";
    Binding.ValueDataType := DbDataType.Float;
// Filtration parameters
    Exporter.ByColumns := False;
    Exporter.CalendarLevel := DimCalendarLevel.Year;
    Filter := Exporter.Filters.Add;
    Filter.Attribute := "COUNTRIES";
    FilterValues := New Variant[2];
    FilterValues[0] := 512;
    FilterValues[1] := 914;
    Filter.ValuesList := FilterValues;
// Export
    Exporter.ClearBeforeExport := True;
    Exporter.Export;
End Sub UserProc;

After executing the example factors are exported to the C:\result_meta_exp.txt file. Data will be exported only for the indicators, which value of the COUNTRIES attribute is equal to 512 or 914. The file consumer is cleared before the export.
