Analysis Services DMX Query Designer User Interface

New: 14 April 2006

Reporting Services provides graphical query designers for building Data Mining Expressions (DMX) queries and Multidimensional Expression (MDX) queries for an Analysis Services data source. When you create a dataset with an Analysis Services data source, Report Designer defaults to the MDX query designer in Design mode. To switch to the DMX query designer, click the DMX (Change to DMX query language view) button. This topic describes the DMX query designer. For more information about the MDX query designer, see Analysis Services MDX Query Designer User Interface.

The DMX graphical query designer has three modes: Design, Query, and Result. To switch modes, right-click on the Query Design pane, and select the mode. Each mode provides a Metadata pane from which you can drag members from the selected cubes to build a DMX query that retrieves data for a dataset when the report is processed.

The query designer toolbar provides buttons to help you design DMX queries using the graphical interface. The following toolbar shows the buttons and describes their functions for all modes of the DMX query designer.
