Help with Calculated member

I'm trying to create a calculate member in SQL Server 2005 that will return a distinct count of clients year to date for all dates within my time dimension. I have figured out that if I create a measure that returns a distinct count then I can use the aggregate function and YTD function to get the distinct count YTD for any date. However, the aggregate function requires a slicer dimension (i think) and every time I put the mdx into the expression box, it does not like the syntax.

I have tried this:

With member [Authorization Service Date].[Calendar].[BlaBla] as

Aggregate(

YTD(

[Authorization Service Date].[Calendar].Current)

)

select [Authorization Service Date].[Calendar].[BlaBla] on columns

from dss

where [Measures].[Authorized Member Distinct Count]

does not like syntax

I have tried this:

Aggregate(

YTD(

[Authorization Service Date].[Calendar].Current)

)

select [Authorization Service Date].[Calendar].[BlaBla] on columns

from dss

where [Measures].[Authorized Member Distinct Count]

does not like syntax

and I have tried this:

Aggregate(

YTD(

[Authorization Service Date].[Calendar].Current)

)

returns error: Error 1 MdxScript(DSS) (67, 4) The function can be called only on a named set. 0 0

I don't know wht this means

Any help would be deeply appreciated

I think you are looking to use the CURRENTMEMBER function instead of CURRENT.

I think this will simply take you to your next challenge. If you run this query, you'll likely get NULL for your result.

I think something like this will better serve your needs:

Code Snippet

With member [Measures].[x] as

COUNT(

EXISTS(

[Customer].[Customer].[Customer].Members,

YTD([Delivery Date].[Calendar].CurrentMember),

'Internet Sales'

)

)

select

[Measures].[x] on columns

from [Adventure Works]

where [Delivery Date].[Date].[June 1, 2002]

;

Bryan,

I appreciate your taking your time to assist me with this. Unfortunately, it did not work. As translated, your mdx on my system looks like

with member [Measures].[x] as

COUNT(

EXISTS(

[CCE Members].[MemberId].Members,

YTD([Authorization Service Date].[Calendar].CurrentMember),

'Authorization Service Days Count'

)

)

SELECT [Measures].[x] ON 0

FROM [dss]

WHERE [Authorization Service Date].[Full Date].&[6303]

I get xError

Just for your info however, I know that all of the underlying attributes and metrics join up properly becuase when I execute:

SELECT [Measures].[Authorization Service Days Count] ON 0,

[CCE Members].[MemberId].Members ON 1

FROM [dss]

WHERE [Authorization Service Date].[Full Date].&[6303]

it works.

Again, your assistance is trully appreciated.

Thanks,

Michael

Two things I noticed in the EXISTS function. Try changing the set to include just the leaf level members:

[CCE Members].[MemberId].Members --> [CCE Members].[MemberId].[MemberId].Members

Also, is 'Authorization Service Days Count' the name of the measure or the measure group? You need to identify the measure group.

Help With a Calculated Member Calculation

Hello,

I have a fact file that includes a measure called Credit Hours. I also have a dimension called DimTerm what includes time data for two terms: 05Fall and 06Fall. My goal is to get a number change between 05 and 06 terms. So I created a calculated member with the logic below but my percentage change is always %0.00. Maybe someone knows a way of doing this through MDX which would allow me to connct to Term values?

([Measures].[Credit Hours] - [Measures].[Credit Hours]) / [Measures].[Credit Hours]

Thanks!

Take a look at the ParallelPeriod function. Your calculated member will look something like

([Credit Hours] - ([Credit Hours], ParallelPeriod(...))) / [Credit Hours]

help with @@IDENTITY

hello,

I've got a problem reading the @.@.identity in vb.net
I tried it the way below and get the error: Public member 'EOF' on type 'Integer' not found.
(--> means with rsLastIdent)

comm_user = "SET NOCOUNT ON; INSERT INTO user (firstname, lastname, company, emailAddress) VALUES ...); SELECT @.@.IDENTITY AS Ident;"
comm = new SqlCommand(comm_user, dbConnection)
dbConnection.Open()
Try
 rsLastIdent = comm.ExecuteNonQuery()
 Catch ex As Exception
 Response.Write("Exception:")
 Response.Write(ex.ToString)
 End Try
if NOT rsLastIdent.EOF then
feed_userID = rsLastIdent.Fields.Item("Ident").Value
end if

The sql-statement is correct - I tried it on SQL Server and got the correct result, so something is wrong with my vb.net code...

Please can anybody help me and tell me how to declare my rsLastIdent or another way to code it in vb.net to get the @.@.identity?

Thanks a lot!

timWhat does ExecuteNonQuery return? It is not what you are trying to get at.

Try .ExecuteScalar() and cast the returned value to an int.

Dim rsLastIdent as integer
rsLastIdent=Integer.Parse(comm.executeScalar().ToString())

There are more elegant ways to do this, I expect.|||Douglas,

Thanks for your help!

executeScalar() was the function I needed! It works perfect now!
