Analysis Services MDX Query Designer User Interface

Due to large amount of questions on “Analysis Services MDX Query Designer” User Interface  we are providing the details below – Source : SQL Server 2008 Books Online (May 2009)

Reporting Services provides graphical query designers for building Multidimensional Expression (MDX) queries and Data Mining Expression (DMX) queries for an Analysis Services data source. This topic describes the MDX query designer. For more information about the DMX query designer, see Using the Analysis Services DMX Query Designer (Reporting Services).

The MDX graphical query designer has two modes: design mode and query mode. Each mode provides a metadata pane from which you can drag members from the selected cubes to build an MDX query that retrieves data 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.

When you edit an MDX query for a report dataset, the graphical MDX query designer opens in Design mode.

The following figure labels the panes for Design mode.

Analysis Services MDX query designer, design view

The following table lists the panes in this mode:

Pane Function
Select Cube button () Displays the currently selected cube.
Metadata pane Displays a hierarchical list of measures, Key Performance Indicators (KPIs), and dimensions defined on the selected cube.
Calculated Members pane Displays the currently defined calculated members available for use in the query.
Filter pane Use to choose dimensions and related hierarchies to filter data at the source and limit data returned to the report.
Data pane Displays the column headings for the result set as you drag items from the Metadata pane and the Calculated Members pane. Automatically updates the result set if the AutoExecute button is selected. .

You can drag dimensions, measures, and KPIs from the Metadata pane, and calculated members from the Calculated Member pane, onto the Data pane. In the Filter pane, you can select dimensions and related hierarchies, and set filter expressions to limit the data available to query. If the AutoExecute (AutoExecute the query) toggle button on the toolbar is selected, the query designer runs the query every time that you drop a metadata object onto the Data pane. You can manually run the query using the Run (Run the query) button on the toolbar.

When you create an MDX query in this mode, the following additional properties are automatically included in the query:

Member Properties   MEMBER_CAPTION, MEMBER_UNIQUE_NAME

Cell Properties   VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS

To specify your own additional properties, you must manually edit the MDX query in Query mode.

Graphical MDX Query Designer Toolbar in Design Mode

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

Button Description
Edit As Text Not enabled for this data source type.
Import Import an existing query from a report definition (.rdl) file on the file system. For more information, see Understanding Report Datasets.
Change to MDX query view Switch to Command Type MDX.
Change to DMX query language view Switch to Command Type DMX.
Refresh result data Refresh metadata from the data source.
Add calculated member Display the Calculated Member Builder dialog box.
Toggle for show empty cells Toggle between showing and not showing empty cells in the Data pane. (This is the equivalent to using the NON EMPTY clause in MDX).
AutoExecute the query Automatically run the query and show the result every time a change is made. Results are shown in the Data pane.
Show Aggregations button Show aggregations in the Data pane.
Delete Delete the selected column in the Data pane from the query.
Icon for the Query Parameters dialog box Display the Query Parameters dialog box. When you specify values for a query parameter, a report parameter with the same name is automatically created. The value of the query parameter is set to an expression that references the report parameter.
Prepare Query button Prepare the query.
Run the query Run the query and display the results in the Data pane.
Cancel the query Cancel the query.
Switch to Design mode Toggle between Design mode and Query mode.
To change the graphical query designer to Query mode, click the Design Mode button on the toolbar.

The following figure labels the panes for Query mode.

Analysis Services MDX query designer, query view

The following table lists the panes in this mode:

Pane Function
Select Cube button () Displays the currently selected cube.
Metadata/Functions/Templates pane Displays a hierarchical list of measures, KPIs, and dimensions defined on the selected cube.
Query pane Displays the query text.
Result pane Displays the results of running the query.

The Metadata pane displays tabs for Metadata, Functions, and Templates. From the Metadata tab, you can drag dimensions, hierarchies, KPIs, and measures onto the MDX Query pane. From the Functions tab, you can drag functions onto the MDX Query pane. From the Templates tab, you can add MDX templates to the MDX Query pane. When you execute the query, the Result pane displays the results for the MDX query.

You can extend the default MDX query generated in Design mode to include additional member properties and cell properties. When you run the query, these values do not appear in the result set. However, they are passed back to Reporting Services and you can use these values in a report. For more information, see Using Extended Field Properties for an Analysis Services Dataset.

Graphical Query Designer Toolbar in Query Mode

The query designer toolbar provides buttons to help you design MDX queries using the graphical interface.

The toolbar buttons are identical between Design mode and Query mode, but the following buttons are not enabled for Query mode:

  • Edit As Text
  • Add Calculated Member (Add calculated member)
  • Show Empty Cells (Toggle for show empty cells)
  • AutoExecute (AutoExecute the query)
  • Show Aggregations (Show Aggregations button)
