IsEmpty (MDX)

  • Artikkeli

Returns whether the evaluated expression is the empty cell value.

Syntax

IsEmpty(Value_Expression)

Arguments

  • Value_Expression
    A valid Multidimensional Expressions (MDX) expression that typically returns the cell coordinates of a member or a tuple.

Remarks

The IsEmpty function returns true if the evaluated expression is an empty cell value. Otherwise, this function returns false.

Note

The default property for a member is the value of the member.

The IsEmpty function is the only way to reliably test for an empty cell because the empty cell value has special meaning in Microsoft SQL Server 2005 Analysis Services (SSAS).

Important

If the evaluation of the value expression returns an error, the function will return false. A value expression can return an error, for example, if a properties reference refers to an invalid or non-existent property.

For more information about empty cells, see the OLE DB documentation.

Example

The following example returns TRUE if Measures.CurrentMember is an empty cell:

IsEmpty(Measures.CurrentMember)
