Analysis Services DMX Query Designer User Interface

Reporting Services provides graphical query designers for building Data Mining Expressions (DMX) queries and Multidimensional Expression (MDX) queries for an Analysis Services data source. 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.

For step by step instructions on how to open the query designer, see How to: Open a Query Designer for a Dataset Query.

The query designer toolbar provides buttons to help you design DMX queries using the graphical interface. The following table describes the buttons and their functions.

When you edit a dataset that uses an Analysis Services data source that has no valid cubes but that does have valid mining models, the graphical query designer opens in Design mode. The following figure labels the panes for Design mode.
