Current (MDX)
Returns the current tuple from a set during iteration.
Składnia
Set_Expression.Current
Arguments
- Set_Expression
A valid Multidimensional Expressions (MDX) expression that returns a set.
Uwagi
At each step during an iteration, the tuple being operated upon is the current tuple. The Current function returns that tuple. This function is only valid during an iteration over a set.
MDX functions that iterate through a set include the Generate function.
[!UWAGA]
This function only works with sets that are named, either using a set alias or by defining a named set.
Examples
The following example shows how to use the Current function inside Generate:
WITH
//Creates a set of tuples consisting of all Calendar Years crossjoined with
//all Product Categories
SET MyTuples AS CROSSJOIN(
[Date].[Calendar Year].[Calendar Year].MEMBERS,
[Product].[Category].[Category].MEMBERS)
//Iterates through each tuple in the set and returns the name of the Calendar
//Year in each tuple
