I've got an issue where I've been presented data in this format from SQL, and have directly imported that into SSRS 2008.
I do have access to the stored procedure for this report, however I don't want to change it as a few other reports rely on it.
Project HoursSpent Cost
1 5 45
1 8 10
1 7 25
1 5 25
2 1 15
2 3 10
2 5 15
2 6 10
3 6 10
3 4 5
3 4 10
3 2 5
I've been struggling all morning to understand how/when I should be implementing the SUM() function with this.
I have tried already to SUM() the rows, but it still outputs the above result.
Should I be adding any extra groups?
Ideally, I need to have the following output:
Project HoursSpent Cost
1 25 105
2 15 40
3 16 30
EDIT: Here is my current structure:
"LineName" is a group for each project
You have to add a row group on "Project" since you want to sum up the data per each project.

So I have a table on a sub report that on the first page has 3 rows of data like this.
(I would post pictures but it wont let me)
Column Column 2 Column 3
1 4 7
2 5 8
3 6 9
Then on the next page the table looks like this.
Column Column 2 Column 3
1 4 7
2 5 8
3 6 9
1 4 7
2 5 8
3 6 9
And so on. Each page has the 3 rows repeated an extra time. The data is all correct at least. Anyone know what could be causing this to happen?
*edited the data to be a little easier to understand
SSRS Question - Is there a way to sum each cell value into
the next colum. Here's what I'm trying to achieve. Colm B displays
the sum of colum A upto that row

You want running totals. Everything you need is here.
Basically it will take each value from a data set and sum it up with the total from all previous values.
Some basic syntax: =RunningValue(Fields!A.Value,Sum,"yourDataSet")
I am working on NGSim Traffic data, having 18 columns and 1180598 rows in a text file. I want to smooth the position data, in the column 'Local Y'. I know there are built-in functions for data smoothing in R but none of them seem to match with the formula I am required to apply. The data in text file looks something like this:
Index VehicleID Total_Frames Local Y
1 2 5 35.381
2 2 5 39.381
3 2 5 43.381
4 2 5 47.38
5 2 5 51.381
6 4 8 504.828
7 4 8 508.325
8 4 8 512.841
9 4 8 516.338
10 4 8 520.854
11 4 8 524.592
12 4 8 528.682
13 4 8 532.901
14 5 7 39.154
15 5 7 43.153
16 5 7 47.154
17 5 7 51.154
18 5 7 55.153
19 5 7 59.154
20 5 7 63.154
The above data columns are just example taken out of original file. Here you can see 3 vehicles, with vehicle IDs = 2, 4 and 5 but in fact there are 2169 vehicles with different IDS. The column Total_Frames tell us how many times vehicle Id of each vehicle is repeated in the first column, for example in the table above, vehicle ID 2 is repeated 5 times, hence '5' in Total_Frames column. Following is the formula I am required to apply to remove data noise (smoothing) from column 'Local Y':
Smoothed Position Value = (1/(Summation of [EXP^-abs(i-k)/delta] from k=i-D to i+D)) * ( (Summation of (Local Y) *[EXP^-abs(i-k)/delta] from k=i-D to i+D))
where,
i = index #
delta = 5
D = 15
I have tried using the built-in functions, which I know of, but they don't smooth the data as required. My question is: Is there any built-in function in R which can do the data smoothing in the way of given formula or which could take this formula as an argument? I need to apply the formula to every value in Local Y which has 15 values before and 15 values after them (i-D and i+D) for same vehicle Id. Can anyone give me any idea how to approach the problem? Thanks in advance.
You can place your formula in a function and then use the apply function of R to apply it to the elements in your "Local Y" column of the dataframe
OK this is the data I am working with:
category_child_id category_parent_id
1 0
2 0
3 1
4 1
5 3
6 3
7 4
8 0
9 8
10 8
11 0
12 11
13 11
14 0
15 14
16 14
17 14
18 0
19 18
20 18
21 18
0 19
It's basically categories with sub categories etc etc.
If I
SELECT category_child_id FROM category_xref WHERE category_parent_id = 1
it returns 3 & 4 which is correct. However there are no products in this category only in the category below so the results I actually want are 5 & 6 as well. However this is not always the same so it does need to be a query.
So basically I need to run a query to get all connected(nested) categories from the table. I've tried many ways with failed results so any help would be great.
If you are using PostgreSQL you could have used "WITH RECURSIVE" but MySQL does not support dynamic, recursive queries. You have to do it with your accessing language (e.g. PHP, Java).
There you can iterate over your recordset and perform a query for each returned child row until no more child rows are returned.
As TRD says, there are extensions to SQL supporting recursive searching of self-joins (Oracle uses 'CONNECT BY') however not only are these not available in MySQL, they're also not the most efficient nor flexible solution.
Have a google for adjacency list model - I did and found this.
I am creating a SSRS 2008 Report
in my report i have 200 columns, it is difficult for visualizing purpose,
is there any way in SSRS by which i can show 20 column per page with row hearer in each page.
ex..
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 .....................
2010 5 4 8 7 6
2011 9 7 5 8 9 4 2 5
2012 1 2 4 5 3
2013
can i break to show only 20 columns in first page & reamin 20 second page & show on with column heaer repeat in each page
Thankyou
Assuming that your column IDs are sequential, simply set up a new column grouping as =Floor(Fields!columnID.Value/20) above your existing column ID grouping and set a page break on your new grouping.
