MDX in Analysis Services: Calculated Members: Leveraging Member Properties - Page 3

November 24, 2003

The purpose of the first-step core query is simply to set up the axes for the enhancements we will make to allow the retrieval and display of member properties. As a useful way to contrast the behavior of the text-string property that we will be attempting to present as a number, we have included a numerical value from the cube, Store Sales, simply to compare to the Store SqFt member property that we will be retrieving.

7.  Save the query with changes as MXAS09-1.

We will now add the syntax required to create a calculated member based upon the Store SqFt member property.

8.  Modify the comment line in the query to read as follows:

-- MXAS09 - 2: Tutorial Query - Step 2

9.  Add the following before the SELECT statement:

WITH 
 MEMBER [Measures].[Store Size] AS 
 'Val(Store.CurrentMember.Properties("Store Sqft"))'

The syntax addition above contains Val, a VBA function that returns numbers contained in a string as a numeric value of appropriate type.

10.  Modify the first line of the SELECT statement as follows:

Step 1 Affected Lines:

   {[Measures].[Store Sales]} ON COLUMNS,

Step 2 Modified Lines:

{[Measures].[Store Sales], [Measures].[Store Size]} ON COLUMNS,

Our query now appears in the Query pane as shown in Illustration 4.
