ToggleDrillState (MDX)

 

Updated: March 2, 2016

Toggles the drill state of members between drilldown and drillllup modes.

  
ToggleDrillState(Set_Expression1,Set_Expression2 [, [RECURSIVE] [,INCLUDE_CALC_MEMBERS] ] )  

Set_Expression1
A valid Multidimensional Expressions (MDX) expression that returns a set.

Set_Expression2
A valid Multidimensional Expressions (MDX) expression that returns a set.

Recursive
(Optional). A keyword that indicates recursive comparison of sets. The ToggleDrillState function is a combination of the DrillupMember and DrilldownMember functions. Recursion only applies when the member is in the DrilldownMember state.

Include_calc_members
(Optional). A flag indicating whether to include calculated members, should they exist, at the drill down level.

The ToggleDrillState function toggles the drill state of each member of the second set that is present in the first set. The first set can contain tuples with any dimensionality, but the second set must contain members of a single dimension. The ToggleDrillState function is a combination of the DrillupMember and DrilldownMember functions. If the member, m, of the second set is present in the first set, and that member is drilled down (that is, has a descendant immediately following it), then DrillupMember(Set_Expression1, {m}) is applied to the member or tuple in the first set. If that m member is drilled up (that is, there is no descendant of m that immediately follows m), DrilldownMember(Set_Expression1, {m}[, RECURSIVE]) is applied to the first set.

If the optional RECURSIVE flag is used, drill up and drill down are applied recursively. For more information about the recursive flag, see the DrillupMember and DrilldownMember functions.

Querying the XMLA property MdpropMdxDrillFunctions enables you to verify the level of support that the server provides for the drilling functions; see Supported XMLA Properties (XMLA) for details.

See Database Journal: MDX Set Functions: The ToggleDrillState() Function for scenarios and examples involving this function.

The following example drills down on the Australia member of the first set, and drills up on the United States member of the first set.

SELECT ToggleDrillState  
   ({[Geography].[Geography].[Country].Members, [Geography].[Geography].[Country].&[United States].Children},  
      {[Geography].[Geography].[Country].[Australia]  
      , [Geography].[Geography].[Country].&[United States]}  
      --, recursive  
      --, include_calc_members  
   ) ON 0  
   FROM [Adventure Works]
