How to build MDX query for two periods of time? - sql

Question

I have the following MDX:
SELECT
NON EMPTY
{
[Measures].[Returns]
,[Measures].[Returns]
} ON COLUMNS
,NON EMPTY
{[Employees].[Company].[Company].ALLMEMBERS}
DIMENSION PROPERTIES
MEMBER_CAPTION
,MEMBER_UNIQUE_NAME
ON ROWS
FROM
(
SELECT
StrToSet
("[Exec Date].[Hierarchy].[Month Num].&[2014]&[1]"
,CONSTRAINED
) ON COLUMNS
FROM [cbSales]
)
WHERE
IIF
(
StrToSet
("[Exec Date].[Hierarchy].[Month Num].&[2014]&[1]"
,CONSTRAINED
).Count
= 1
,StrToSet
("[Exec Date].[Hierarchy].[Month Num].&[2014]&[1]"
,CONSTRAINED
)
,[Exec Date].[Hierarchy].CurrentMember
);
Both columns shows returned data for month 2014/01
I want to have data for the next month (2014/02) in the second column.
How can I change the query to achieve my goal.

Answer 1

I'll try to replicate with AdvWks cube, so currently not tested:
WITH
MEMBER [Measures].[ReturnsNextMth] AS
(
[Measures].[Returns]
,[Exec Date].[Hierarchy].CurrentMember.NextMember
)
SELECT
NON EMPTY
{
[Measures].[Returns]
,[Measures].[ReturnsNextMth]
} ON COLUMNS
,NON EMPTY
{
[Employees].[Company].[Company].ALLMEMBERS
*
[Exec Date].[Hierarchy].[Month Num].ALLMEMBERS
} ON ROWS
FROM
(
SELECT
StrToSet
("[Exec Date].[Hierarchy].[Month Num].&[2014]&[1]"
,CONSTRAINED
) ON COLUMNS
FROM [cbSales]
);
Something similar in AdvWks:
WITH
MEMBER [Measures].[ReturnsNextMth] AS
(
[Measures].[Internet Order Count]
,[Date].[Calendar].CurrentMember.NextMember
)
SELECT
NON EMPTY
{
[Measures].[Internet Order Count]
,[Measures].[ReturnsNextMth]
} ON COLUMNS
,NON EMPTY
{
[Sales Territory].[Sales Territory].[Country].MEMBERS
*
[Date].[Calendar].[Month].ALLMEMBERS
} ON ROWS
FROM
(
SELECT
[Date].[Calendar].[Month].&[2008]&[1] ON COLUMNS
FROM [Adventure Works]
);
This gives these results. I found this quite surprising as the sub-select seems to suggest we only have Jan-2008 available, but sub-select is a bit of a strange creature. This article explains: http://bisherryli.com/2013/02/08/mdx-25-slicer-or-sub-cube/. So our measure [ReturnsNextMth] still functions ok.
