Max (MDX)

  • Artigo

Returns the maximum value of a numeric expression that is evaluated over a set.

Syntax

Max( Set_Expression [ , Numeric_Expression ] )

Arguments

  • Set_Expression
    A valid Multidimensional Expressions (MDX) expression that returns a set.
  • Numeric_Expression
    A valid numeric expression that is typically a Multidimensional Expressions (MDX) expression of cell coordinates that return a number.

Remarks

If a numeric expression is specified, the specified numeric expression is evaluated across the set and then returns the maximum value from that evaluation. If a numeric expression is not specified, the specified set is evaluated in the current context of the members of the set and then returns the maximum value from that evaluation.

Note

Analysis Services ignores nulls when calculating the maximum value in a set of numbers.

Example

The following example returns the maximum quarterly sales for each subcategory and each country in the Adventure Works cube.

WITH MEMBER Measures.x AS Max 
   ([Date].[Calendar].CurrentMember.Children
      , [Measures].[Reseller Order Quantity]
   )
