Reporting Services: Show top N Rows with Grouping - reporting-services

I am trying to show the top 10 rows in my report. I can do this by setting the following expression for the Visibility of the row group:
=IIF(RowNumber(Nothing) <= 10, false, true)
and then sorting the table on the top numbers.
In my query I get two rows for each result, with different results. The problem is that I want to group these rows into one row in the report without losing the count for top X rows. But when I group on the name in my report in Visual Studio, it only shows every row one time and the count for X rows get incorrect. Sometimes I have the same name once and sometimes twice. I have tried to set the expression to 20 rows, but then I might get 12 rows sometimes and 10 rows sometimes, depending on how many rows for each name my query returns.
Thanks in advance,
Sara

It sounds like you need to top N after you group. Can you group in you query?

SSRS Report - Badges

Is there an easy way to do a page of badges in an SSRS report? I am looking at 2 across and 3 down per page based on a list. I have built one so far of a single column using a list box but the problem is that it is not advancing to the next record and shows me the same record over and over until I get to the end of the count of total records in the dataset so I know I am doing something wrong. I am using Visual Studio 2017
I use a matrix when I am making a grid with boxes that go across and down.
First I add a ROW_NUMBER to the query to have the order in which to show the records. I subtract 1 so the values start with 0.
SELECT *, ROW_NUMBER()OVER(ORDER BY EFF_DATE) - 1 ROW_NUM
FROM BLAH_BLAH...
Then in SSRS, add 2 Calculated Fields to the dataset with the ROW_NUM.
The first is named ROW. It will have an integer with the row that the record will end up in.
=INT(Fields!ROW_NUM.Value / 2)
The second is COLUMN that will give the a column number.
=Fields!ROW_NUM.Value MOD 2
Then in the matrix, set the grouping based on the calculated fields.
COLUMN GROUP
Group and Sort by COLUMN
ROW GROUP
Group and Sort by ROW
The 2 can be changed to use whatever number of columns is needed.

SSRS, return rows into a grid layout

I have a dataset that I need to arrange into a grid on a page (export to pdfs) as a customer report. Each row in my dataset needs to display as a cell. Each page would have roughly 3 records displayed as columns and then 4 rows of records. e.g. a (3x4 grid), being 12 records per page.
Right now I am using a matrix to display my results, but I cannot find how to get my matrix to start a 2nd row after 3 columns are generated.
Is this feasible or should I find a different solution to create these reports?
I was thinking may be if I had row groups to use, but not sure how to create a column that creates a repeating result 3 times then adds 1 to the next 3 results in my query. 111,222,333,444 and that could be my row grouping?
Here's what I use in a matrix to create a grid of columns from a single cell.
Add a ROW_NUMBER field to the dataset query and subtract 1 with the ORDER BY using the field to be ordered by.
ROW_NUMBER()OVER(ORDER BY DISPLAY_NAME) - 1 AS ROW_NUM
Add Calculated Fields to the dataset using the ROW_NUM.
Call the first COLUMN and MOD row_num by 3 to get values or 0 - 2 for the column number:
=Fields!ROW_NUM.Value MOD 3
Call the second calculated field ROW and get the INT of ROW_NUM divided by 3 to get the row number for the record:
=INT(Fields!ROW_NUM.Value / 3)
Then the matrix would have the Column grouping (and sorting) based on the COLUMN field and the Row grouping on the ROW field.
You could use a parameter as the number of columns (3) to make it easy to change.

Calculate Min and Max for aggregation in SSRS report

My SSRS report have a dataset that will return the following result. The result set for some reason may not be changed. Note that Category - SubCategory pair might not be distinct.
Category Sub-Category Value
-----------------------------
A A1 100
A A2 120
A A2 60
B B1 80
B B2 90
B B2 70
I want to show the max value and main value for each of the SUM(category, subCategory) in report matrix, as exactly the format as follows (except the comment in bracket):
Max | 180 (two A-A2 rows)
Min | 80 (B-B1)
How can I define the matrix and write the expression? If make a group on these two columns, The matrix will show four rows regardless of what expression I set.
I tried to run your use case on my local SSRS.
On Left hand side I have original Data and on Right hand side I have the desired result you expect.
What you need is grouping as below
Expression for sum as below
Put a tablix into your report. Then at Row Groups (bottom) click on the (Details) and chose Add Group > Parent Group. Click the Add group header and chose your Sub-Category. Do the same with your Category. Your Row Grouping hierarchy should be now Category > Sub-Category > Details.
Now you see the brackets on the left in your tablix, they indicate the level. If you use now the following expression with their group name on the specific level, you will get what you want.
'At the Category group level header
=Sum(Fields!Value, "CategoryGroupName")
'At the Sub-Category group level header
=Sum(Fields!Value, "SubCategoryGroupName")
I got the way to make it. The solution is as follows:
Make a row parent group called row. Let the group group by a constant.
Make a child group category under the row group which is grouped by Category.
In matrix cell which is inside the group, Add this expression: =Min(Sum(Fields!Value.value), "Category"), "row"). that's the reason why I make a constant group, because I want to make the nested aggregate function legal.
This expression will return all values identical within the Category group. Now add another row outside of these row groups. Pick a cell and enter =ReportItems!ThatTextBox.Value.
Hide the row which consists your groups.
Do the same for MAX value (Start from adding an adjacent group, grouping by constant)

Mysql query to only return rows based on column of first row

Sorry for the title, hard to explain in one line, but I am after a query that can get me all the rows based on the result of the first row - an example will explain:
Table looks like this
id | name | week
1 x 2
2 y 2
3 z 3
So basically without knowing the first week value, I want only those rows where week = 2. In other words, if the next run, the first result is week: 3, then I only want rows where week = 3.
This is all contingent on the correct ordering of the rows - but that is not the purpose of this.
I've thought about doing it in two queries given this be inside some php app, where the first query
select week from table limit 1
And therefore, now we know the week value, can simply
select id, name, week from table where week = '2'
But I figured there was a smarter way to do it in one query, just not sure what that sql function might look like.
Hope that makes sense.
Expanding from your steps and thinking, you could do
SELECT * FROM table WHERE week = (SELECT week FROM table LIMIT 1)
The above should work fine (unless I misunderstood the question).

ssrs count error getting 1's instead of total

Rookie mistake,
here it is:
I got Regions and MembersID, I grouped the regions and want to count the members. When I add the count(MembersID) instead of geeting the total members, I get a bunch of 1:
RegionA 1
1
1
RegionB
1
1
what I want:
RegionA
3
RegionB 2
what I did: Grouped Regions and Count[MembersID]
Please help!
It's a bit tough to tell what you actually need here.
In Group Header rows, you can use aggregate functions, which will look at all rows in that current scope.
Distinct MembersID count in group: =CountDistinct(Fields!MembersID.Value)
Total rows in group: =CountRows()
In detail rows, these aggregate functions will only report on the current rows, so =CountRows() will only ever return one; to get the number of rows in the group you need to set the scope of the function to the group level, e.g. something like =CountDistinct(Fields!MembersID.Value, "Group1") or =CountRows("Group1").
So based on a Dataset:
And a report which incorporates these aggregate function in the group header and detail rows:
You can get the following results:
If this is not sufficient you will need to supply your Dataset details, some sample data and how you need this sample data presented.
