问题 Looking at the diagram for our ClientId hierarchy I see a pattern that is repeated in most hierarchies: If I expand All then every member of that hierarchy is included - is All a level as well as a member? 回答1: All, is the parent member of all the members of an attribute whose propertey "IsAggregatable" is set to TRUE. ALL is also a level that contains the All-member(s). Depending what you are using the following statements can return a reasonable result or an Error, so I would it is good to

问题 I am partitioning my cube by the most recent 13 months, and then a legacy partition to hold older months. I have successfully created dynamic partitions, but now I need to add a dynamic slice to each partition. I thought I could use this in the Partition Slice Expression: [Dim Date].[Month].&[" + CStr(Month(Now())) + "].lag(8) but it's failing. Does anyone have any ideas? 回答1: I tried all day, but ultimately resolved that partition slice expressions dont like anything that is not a dimension

问题 Is there a way to create a calculated measure that can do a distinct count, but excluding the null values? For example, if I have: 10, 20, 20, null; the distinct count is 3, but can I have the answer as 2? 回答1: put a where condition to where the measure is not null 回答2: you could try this: with cte ( "counter" ) as ( select 1 as "counter" from "YOURTABLE" group by "COLUMNNAME" having ( "COLUMNNAME" IS NOT NULL ) ) select SUM( "counter" ) from cte @ edit: quite easier variant: SELECT COUNT(

问题 I have a database containing tables with more than 600 million records and a set of stored procedures that make complex search operations on the database. The performance of the stored procedures is so slow even with suitable indexes on the tables. The design of the database is a normal relational db design. I want to change the database design to be multidimensional and use the MDX queries instead of the traditional T-SQL queries but the question is: Is the MDX query better than the

问题 I am trying to create a calculated member to calculate the nb of employees YTD. By YTD I mean the number of employees for any given period of time.My fact table has 2 date dimensions StartDate and EndDate. I would like to calculate YTD employees as follows. Members with StartDate equal to or before current period AND EndDate in the current period OR EndDate is NULL 回答1: I had a similar task and end up with the following solution: SUM( [EmployeeChanging].[EmployeeChanging].[EmployeeChanging]

问题 In order to give a nicer Cube browsing experience to end users, I am trying to create a Time Periods hierarchy consisting of Calculated Members. Currently I have used a Calculated Column in my DSV to create a column with the same value on every row in my Dates table (value is All Time ). Then within my Date and Time dimension I have created a single level, single member hierarchy using that Calculated Column, which looks like this: Now what I have already successfully done is add Time Periods

问题 I have created an MDX query which calculates the TOP 10 ZipCodes (according to my Patient Stay measure) as such: WITH MEMBER [Discharge Date].[Y-M-D].[ Aggregation] AS 'AGGREGATE( EXISTING { [Current Month] } )', SOLVE_ORDER = 0 SELECT NON EMPTY { [Measures].[Patient Stays] } ON COLUMNS, TOPCOUNT({ ORDER( HIERARCHIZE( { [Patient].[ByZipcode].[All].CHILDREN } ), ( [Measures].[Patient Stays] ), BDESC ) }, 10) ON ROWS FROM [Patient Stay] WHERE ( [Discharge Date].[Y-M-D].[ Aggregation], [Facility

问题 I have the following expression in Excel that works fine. =CUBESET("ThisWorkbookDataModel", "TopCount( [ProductBV].[Product Name].Children,10, sum( ( [Calendar].[Week Ending].[All].[1/6/2013]:[Calendar].[Week Ending].[All].["&TEXT($E$2,"m/d/yyyy")&"], [ProductBV].[Moderation Status (ALL)].[All].["&$E$3&"] ), [Measures].[Product Review Count] ) )", "Top 10 to date") The Product Review Count measure using the following DAX formula. Product Review Count:=COUNTROWS(ProductBV) However, when I

问题 I am having some issues trying to implement an average of a dimension attribute. The basic structure is: Booking Header Dimension Fact Table (multiple rows per Booking Header entry) On the booking header dimension I have a numerical attribute called Booking Window, and I want to be able to create a calculated measure that averages this value. We are using SQL Server 2012 standard edition. Any help would be greatly appreciated. 回答1: The best approach would be to create a measure group from the

问题 I am relatively new to this depth of MDX, but here is my dilemma. My goal is to implement a calculated member using a .Net Stored Procedure. The calculation (XIRR) will be based on a set of cash flow dates and cash flow amounts. Ideally this would be a calculation in my cube that is available as a measure to Excel/Browser users. So to start simple I am just trying to implement my own COUNT calculated member/measure (not even using .Net) to say count the # of members in a given dimensions
