Help with custom total in matrix (hopefully easy adjustment)

Hey guys. I have a matrix that is working the way I want it as far as
groupings and data. I am doing a custom total that works for the first row
group with the following code:
Private currentTotal As Double = 0
Function SetCurrentValue(ByVal currentValue As Double) As Double
currentTotal += currentValue
return currentTotal
End Function
Function GetCurrentValue() As Double
return currentTotal
End Function
Function ResetTotal() As Boolean
currentTotal=0
return True
End Function
In my detail I have:
=IIf(Fields!WC_GROUP.Value = "007", Code.MyFunc(Fields!WC_GROUP.Value,
Fields!WC_TOTALS_DIVIDEND_ROUNDED.Value),
IIf(Fields!WC_GROUP.Value = "008", Code.MyFunc(Fields!WC_GROUP.Value,
Fields!WC_TOTALS_DIVIDEND_ROUNDED.Value), Nothing))
If I use only the first IIF statement I get the correct values 19, 38 , 57,
76, 95, 114, 133, 152, 171, 190, 209, and 228.
If I use both IIf statements I get 19, 57, 95, 133, 171, 209, 247, 285, 323,
361, 399, 437 in the first row and in the second row I get:
494, 532, 570, 608, 646, 684, 722, 760, 798, 836, 874, 912
I need to run the reset method in between row groupings to get it to go back
to 19 for the second row (it will be a different starting value eventually,
but for now I need it to reset).
I tried putting the code as a second row grouping and the column subtotal,
but it won't reset in the proper spot. Let me know!
Thanks!,
BJYou can use rownumber with scope/group so that it resets each and everytime
group changes. Provided your 19,38,57 etc.. are fixed values...

Help with a matrix or pivot table?

I'm trying to create a table that is a combination of two tables, and the number of columns is dynamic. So I have 2 tables, Students and Assignments. I'd like to get a result with the students on the left and the assignments across the top. I'm not sure where to start, any help would be great. Thanks

What your describing is not (1) a table, (2) a view nor (3) a table valued function because none of these can contain a dynamic number of columns. Where you need to start is by describing more clearly your needs.

If you are using SQL Server 2005 you probably use the ROW_NUMBER() function and PIVOT to slot different classes into ordinally assigned columns. This might be done with either a view or a TVF; however, if you truly need a dynamic number of columns, first rethink this at least a little. Once you decide you need a dynamic number of columns, you will need to settle with dynamic SQL.

|||

I'll try to be more clear. I need to display a table that has a row for each student. For each student row I'd like to have a column for each assignment completed. The tables look like this. The number of assignments could be 0 to 100, so the number of columns is dynamic.

tblStudent

StudentId

Name

tblAssignment

AssignmentId

StudentId

Score

Example

Assignment 1 | Assignment 2 | Assignment 3

Student X 10 20 30

Student Y 5 15 40

Help w/aggregate function in Matrix

On a report we have a matrix. The data cell has the following expression:
=iif(Fields!Score.Value=0, "", Fields!Score.Value)
When we run the report, we get the following warning:
The value expression for the textbox 'Score' references a field
outside an aggregate function. Value expressions in matrix cells should be
aggregates, to allow for subtotaling.
What does this mean and how can I resolve it?
The goal it to suppress the display of zero (0). We have tried setting the
format of the data cell to be "#", but the zero is still displayed. So we
have been using expressions like the above to achieve this.
The user creating this report is using the stand-alone C# IDE with Reporting
Services. This warning prevents them from previewing the report. Another
user using VS.NET 2003 is able to preview the report despite the warning.
The report renders on our test reporting server. If we need to just ignore
the warning, how can we get the user using C# to be able to preview the
report?
Thanks,
ChrisMatrix cells are always in the scope of two groupings and you could have
multiple data rows which match the group instance values. Therefore, you
should always use aggregate functions when referencing fields in a matrix
cell (hence, a processing warning gets generated).
If you don't use an explicit aggregate function in the matrix cell, we would
implicitly use the first row's field value. I believe you actually don't
want just the first value, but rather the sum - so you should change the
expression to:
=iif(Sum(Fields!Score.Value)=0, "", Sum(Fields!Score.Value))
