## MDX Essentials: Enhancing CROSSJOIN() with Calculated Members - Page 8April 4, 2005 Based upon what we know about the 3. Scroll down in the viewer to ascertain that the Click for larger image As we noted in our previous article, there are many "empties" that we might attempt to eliminate as a first step in enhancing query performance. The complication within our current enhancement effort lies in the expressed business requirement to return the 4. Save the query as 5. Create the following new query, where we substitute the
6. Execute the query using the The query executes far more rapidly, and the empties are eliminated. We note, however, if we attempt to scroll to the Fortunately, as we have seen myriad times in the past, MDX offers alternative approaches to meeting our needs. To accomplish our ends, enhancement of the query with retrieval of the calculated member, we can employ a combination of the 7. Save the query as Fortunately, as we have seen myriad times in the past, MDX offers alternative approaches to meeting our needs. To accomplish our ends - enhancement of the query with retrieval of the calculated member - we can employ a combination of the 8. Create the following new query, where we substitute the new approach
9. Execute the query using the The query returns in far less time than in its original incarnation. In addition, the absence of empties is pronounced. Finally, we see, if we scroll once again to our calculated member The query we have constructed is faster than the original query, and is faster than would be the application of the filter to both 10. Save the query as 11. Close the We report our success to the information consumers, detailing the steps we took and documenting the modifications to the query. We conclude by expressing our hopes that other disrupted development projects that were in the hands of the offshore organization meet with successful recoveries, as well. ## Summary ...In this article, we continued our examination of the enhancement of queries using the powerful In a multi-step practice exercise, we determined that
