I have the following Expression in a field in SSRS:
=iif(Fields!Score.Value > Previous(Fields!Score.Value),"Greater","Less Than")
I have the following Scores in my scenario across 4 rows:
3
3
4
5
It results in:
3 - Greater
3 - Less Than
4 - Greater
5 - Greater
The issue is with the first row always being Greater. It should be blank because there isn't a previous row to compare against. I would expect the results to be as follows:
3 -
3 - Same
4 - Greater
5 - Greater
How could I change the above formula to produce the above result?
The above is an example of only one row group. There are then further row groups with different Scores, so the different results of Same/Greater/Less Than need to work across the different row groups.
Try following:
=IIF(RowNumber(NOTHING)=1,"",IIF(Fields!Score.Value = Previous(Fields!Score.Value),"Same",IIF(Fields!Score.Value > Previous(Fields!Score.Value),"Greater","Less Than")))
modified. try now.

I have a data set in google sheets, for each week of data I have 3 rows. I wish to query the data in every second row to calculate the max value and the last value.
For instance:
ROW
DATA
1
800
2
Text
3
500
4
More text
5
600
6
Blah
7
700
8

For Max value I have the following which will return 800
MAX(FILTER(QUERY(A1:A,"Select * skipping 2"), QUERY(A1:A,"Select * skipping 2") <> 0))
How do I change it up to return the last value? Which should return 700
try:
=LOOKUP(2^99,FILTER(A:A,A:A<>0))
#rockinfreakshow answer will successfully find the last number.
To filter a range by n amount of rows, you can use:
=FILTER(A:A,MOD(ROW(A:A),n)=1)
Change n with your desired value, and 1 with the number of row you want to get. 1 for the first, 2 for the second, but 0 if you want the nth one. To find MAX, just wrap it in MAX()
To find the last one, even if it's a text or number, you can use SORTN and SEQUENCE:
=SORTN(FILTER(A:A,MOD(ROW(A:A),n)=1,A:A<>""),1,1, SEQUENCE(COUNTA(FILTER(A:A,MOD(ROW(A:A),n)=1,A:A<>""))),0)
It orders the elements in reverse order and only chooses the first one
Remember to change n with the number of rows and =1 with the number of row you want to choose
I have a table that looks like:
col1
------
2
2
3
4
5
6
7
with values sorted in ascending order.
I want to assign each row to groups with labels 0,1,...,n so that each group has a total of no more than 10. So in the above example it would look like this:
col1 |label
------------
2 0
2 0
3 0
4 1
5 1
6 2
7 3
I tried using this:
floor(sum(col1) OVER (partition by ORDER BY col1 ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) /10))
But this doesn't work correctly because it is performing the operations
as:
floor(2/10) = 0
floor([2+2]/10) = 0
floor([2+2+3]/10) = 0
floor([2+2+3+4]/10) = 1
floor([2+2+3+4+5]/10 = 1
floor([2+2+3+4+5+6]/10 = 2
floor([2+2+3+4+5+6+7]/10) = 2
It's all coincidentally correct until the last calculation, because even though
[2+2+3+4+5+6+7] / 10 = 2.9
and
floor(2.9) = 2
what it should do is realise 6+7 is > 10 so the 5th row with value 7 needs be in its own group so iterate the group number + 1 and allocate this row into a new group.
What I really want it to do is when it encounters a sum > 10 then set group number = group number + 1, allocate the CURRENT ROW into this new group, and then finally set the new start row to be the CURRENT ROW.
This is too long for a comment.
Solving this problem requires scanning the table, row-by-row. In SQL, this would be through a recursive CTE (or hierarchical query). Hive supports neither of these.
The issue is that each time a group is defined, the difference between 10 and the sum is "forgotten". That is, when you are further down in the list, what happens earlier on is not a simple accumulation of the available data. You need to know how it was split into groups.
A related problem is solvable. The related problem would assign all rows to groups of size 10, splitting rows between two groups. Then you would know what group a later row is in based only on the cumulative sum of the previous rows.
I have data like this
EmployeeID Value
1 7
2 6
3 5
4 3
I would like to create a DAX calculated column (or do I need a measure?) that gives me for each row, Value - AVG() of selected rows.
So if the AVG() of the above 4 rows is 5.25, I would get results like this
EmployeeID Value Diff
1 7 1.75
2 6 0.75
3 5 -0.25
4 3 -1.75
Still learning DAX, I cannot figure out how to implement this?
Thanks
I figured this out with the help of some folks on MSDN forums.
This will only work as a measure because measures are selection aware while calculated columns are not.
The Average stored in a variable is critical. ALLSELECTED() gives you the current selection in a pivot table.
AVERAGEX does the row value - avg of selection.
Diff:=
Var ptAVG = CALCULATE(AVERAGE[Value],ALLSELECTED())
RETURN AVERAGEX(Employee, Value - ptAVG)
You can certainly do this with a calculated column. It's simply
Diff = TableName[Value] - AVERAGE(TableName[Value])
Note that this averages over all employees. If you want to average over only specific groups, then more work needs to be done.
To set the scene, what I define as identical rows are when the combination of destination and vehicle_brand are the same. For instance in the figure below,
SQL table name: cardriven
rows 2 and 3 are "identical" because of the Dallas-Toyota "combination." Now I want to only display the row with the higher request_id. So for example, between rows 2 and 3, row 3 would get displayed and row 2 would be hidden/removed because 169 > 100. So in the end, only rows 3, 4, 5, 7, and 8 will show and rows 1, 2, 6, and 9 would get hidden/removed.
Hopefully you understand what I am going for here but if you have any questions, please let me know. This will be written in SQL code.
Another problem: I added a new column for dates and entered some random ones for rows 2-4. Row 2 is 12/1/17, row 3 is 11/5/2016, and row 4 is 7/6/2017. Note that row 3 has the highest request_id out of the Dallas-Toyota combination. I decided to enter a new entry in with a request_id = 501 and entry of Dallas, Toyota, and 12/22/2017. After running the program, for Dallas-Toyota I return row 3 but with request_id = 501! It SHOULD return the entry I just entered.
You can use Group By and the Max function to get the highest value.
SELECT MAX(request_id), destination, vehicle_brand
FROM cardriven
GROUP BY destination, vehicle_brand
So I have a column with this data
1
1
1
2
3
4
5
5
5
how can I do a count if where the value at any given location in the above table is equal to a cell i select? i.e. doing Count([NUMBER]) Where([NUMBER] = Coordinates(0,0)) would return 3, because there are 3 rows where the value is one in the 0 position.
it's basically like in excel where you can do COUNTIF(A:A, 1) and it would give you the total number of rows where the value in A:A is 1. is this possible to do in business objects web intelligence?
Functions in WebI operate on rows, so you have to think about it a little differently.
If your intent is to create a cell outside of the report block and display the count of specific values, you can use Count() with Where():
=Count([NUMBER];All) Where ([NUMBER] = "1")
In a freestanding cell, the above will produce a value of "3" for your sample data.
If you want to put the result in the same block and have it count up the occurrences of values on that row, for example:
NUMBER NUMBER Total
1 3
1 3
1 3
2 1
3 1
4 1
5 3
5 3
5 3
it gets a little more complicated. You have to have at least one other dimension in the query to reference. It can be anything, but you have to be counting something in conjunction with the NUMBER dimension. So, the following would work, assuming there's another dimension in the query named [Duh]:
=Count([NUMBER];All) ForAll([Duh])
