CurrentOrdinal (MDX)

New: 17 July 2006

Returns the current iteration number within a set during iteration.

Syntax

Set_Expression.CurrentOrdinal

Arguments

• Set_Expression
  A valid Multidimensional Expressions (MDX) expression that returns a set.

Remarks

When iterating through a set, such as with the Filter (MDX) or Generate (MDX) functions, the CurrentOrdinal function returns the iteration number.

Example

The following example returns the number of products in the set that are unique, using the Order function to order the non-empty tuples before utilizing the Filter function. The CurrentOrdinal function is used to compare and eliminate ties.

WITH MEMBER [Measures].[PrdTies] AS Count
   (Filter
      (Order
        (NonEmpty
          ([Product].[Product].[Product].Members
          , {[Measures].[Reseller Order Quantity]}
          )
       , [Measures].[Reseller Order Quantity]
       , BDESC
       ) AS OrdPrds
    , (OrdPrds.CurrentOrdinal < OrdPrds.Count 
       AND [Measures].[Reseller Order Quantity] = 
          ( [Measures].[Reseller Order Quantity]
            , OrdPrds.Item
               (OrdPrds.CurrentOrdinal
               )
            )
         )
         OR (OrdPrds.CurrentOrdinal > 1 
            AND [Measures].[Reseller Order Quantity] = 
               ([Measures].[Reseller Order Quantity]
               , OrdPrds.Item
                  (OrdPrds.CurrentOrdinal-2)
                )
             )
          )
       )
SELECT {[Measures].[PrdTies]} ON 0
FROM [Adventure Works]
