I am using tableau and am stuck in making the field of the following code unique.
"COUNTD(
IF NOT(ISNULL([firstBillingDate]))
THEN [msisdn]
ELSE NULL
END
)"
Basically its counting unique msisdn's for all the columns which have firstbillingDate present (NOT NULL).
The problem is that one msisdn has more than one firstBillingDate. I want to count unique msidns which has only ONE firstbillingdate
Instead of using [firstBillingDate] in that calculation, create an LOD calc to only retrieve one date per msisdns.
{fixed [msisdns] : min([firstBillingDate]}
You can use max or min. I assumed you'd want min to return the earlier date for any multiple dates per msisdns. Now use this in your original calc.

enter image description hereI am trying to design a report in ssrs that returns the last opening stock for each product in the dataset. To achieve this I used
=Last(Fields!CustProdAdj_new_openingstockValue.Value).
This works fine. But where I encountered a problem is in getting the sum of all the opening stock for each product. I tried using
=sum(Last(Fields!CustProdAdj_new_openingstockValue.Value))
but I got the error message
[Error on Preview]
Please is there another way to go about this
I have tried using aggregate(), runningValue(), to no avail
This is the dataset
This is the report layout
On previewing having used max()
This is probably easier to do directly in the dataset query but assuming you cannot change that, then this should work...
This assumes your data is ordered by the CustProdAdj_createdon column and that this is a date, datetime or some other ordered value, change this bit if required.
=SUM(
IIF(Fields!CustProdAdj_createdon.Value = Max(Fields!CustProdAdj_createdon.Value, "MyRowGroupNameHere"),
CustProdAdj_new_openingstockValue,
0)
)
Change the MyRowGroupNameHere to be the name of the rowgroup spelled exactly as it is in the rowgroup panel below the main design panel. Case sensitive and include quotes.
What this does is, for each row within the rowgroup "MyRowGroupNameHere", compare the CustProdAdj_createdon date to the max CustProdAdj_createdon across the rowgroup. . If it is the same then return the CustProdAdj_new_openingstockValue else return 0.
This will return the value required on only 1 record within the group.
For example, if you had 1 row per day then only on the last day of the month would a value be returned other than 0 because only the date of the last record would match the maximum date within the group.
Then it simply sums the results of this up.
I have a SQL table like this and I want to find the average adjusted amt for products partitioned by store_id that looks like this
Here, I need to compute the adj_amt which is the product of the previous two columns.
For this, I need to fill the nulls in the avg_quantity with the first non_null value in the partition. The query I use is below.
select
CASE WHEN av_quantity is null then
# the boolen here is for non-null values
first_value(av_quantity, True) over (partition by store_no order by product_id
range between current row and unbounded following
)
else av_quantity
end as adj_av_quantity
I'm having trouble with the SQL required to get the adjusted cost, since its not pulling the first non_null value for factor but still fetches it based on the same row for the adj_av_quantity. any thoughts on how I could do this?
FYI I've simplified the data here. The actual dataset is pretty huge (> 125 million rows with 800+ columns) so I won't be able to use joins and have to do this via window functions. I'm using spark-sql
I have the following question!
I have a table like this:
Data Source
I want to create a field(i suppose it's a field) that i can take the apl_ids,
that have as service_offered some that i want.
Example from the above table. If i want the apl_ids that have ONLY the service_offered
Pending 1, Pending 2 and Pending 7.
In that case, I want to get the apl_id = "13" since apl_id = "12" got one more service that i don't need.
Which is the best way to get that?
Thank you in advance!
Add a calculated field which gives 1 for desired values and 0 for other values. Add another calc field with fixed LOD to apl_id to sum of calcF1. Filter all ids with values=3 only. I think that should work.
Else tell me I will post screenshots
You can create a set based on the field api_id defined by the condition
max([service_offering]=“Pending 1”) and
max([service_offering]=“Pending 2”) and
max([service_offering]=“Pending 7”) and
min([service_offering]=“Pending 1” or [service_offering]=“Pending 2” or [service_offering]=“Pending 7”)
This set will contain those api_ids that have at least one record where service_offering is “Pending 1” and at least one record with Pending 2 ... and where every record has a service offering of 1, 2 or 7 (I.e. no others)
The key is to realize that Tableau treats True as greater than False, so min() and max() for boolean expressions correspond to every() and any().
Once you have a set of api_ids() you can use it on shelves and in calculated fields in many different ways.
I'm working on SSRS report builder that is using a dataset calling a SQL Server 2000 database.
The query is getting sums of a few different fields and is also pulling out all records that have to do with that client number. I want to get the sum of the sum but it is way over because of the detail rows. Basically what I want is the sum of the distinct sum column values.
=Sum(Fields!tot.Value, "table1_Group3")
I saw that you can get sums by the groups and I tried the expression above but it comes back with an error:
The Value expression for the textbox 'tot' has a scope parameter that is not
valid for an aggregate function...
table1_Group3 is the name of the group that holds the sum value in the report.
Any suggestions on how to get the distinct values to sum them in this report.
=Sum(Fields!tot.Value, "table1_Group3")
The code above will give you the sum of "tot" for all rows in the current "table1_Group3." This means that this expression only makes sense somewhere within table1_Group3. Otherwise, SSRS doesn't know which is the current instance of that group.
Sounds like you would like to sum this value across multiple groups, but only take one "tot" from each instance of the group. (Are you sure that all rows in that group will have the same "Tot?")
If tot is the total of other fields in your returned data, then simply add those up in your formula. This may have the added benefit of simplifying your SQL query as well.
Some other options that could work:
- Change your SQL query so that only one row per group gets the Tot field set.
- Use Embedded code in the report to keep a running total which is added to only once per group, such as in the group header.
(If upgrading to 2008R2 SSRS is an option, then the Lookup function could be used here, maybe even to look back at the same dataset.)
change the query/ dataset to sum(distinct tot) using the temp table on the sql server
I suppose you need to write sum(distinct columnName).
I am trying to use Set Analysis in the table below for the column labelled test. I am trying to get sum([Best Dollar]) for the date range specified by the Start and End columns.
This expression returns results, but it's naturally static for each row of the table:
=sum({$<AsAtDate={">=40959 and <=40960"}>} [Best Dollar])/1000
This is what I want to have but it returns 0:
=Sum({$<AsAtDate={">=(num(floor(BroadcastWeekStart2))) and <=(num(floor(BroadcastWeekStart2)))+6"}>} [Best Dollar])/1000
To obtain unique start date serial numbers for each line for the start column (BroadcastWeekStart2) I use the following expression:
=(num(floor(BroadcastWeekStart2)))
How can I specify that the values or calculations used for the start and end columns are used in Set Analysis for the field above?
There is at least one information missing in your question.
Do you want to select on fixed values or should the sum depend on the current time?
For the static version something like
=sum( {$<BroadcastWeekStart2={"40959"}, BroadcastWeekStart2={"<=40960"}>} [Best Dollar])/1000
should work. (Assuming that BroadcastWeekStart2 contains these kind of values.)
Let me show you an example how I calculate values for the current week:
='Count: ' & count({$<start_week={"$(=WeekStart(Today()))"}>} Games)
where the start_week is set in the load script by:
WeekStart(date#(#4, 'YYYYMMDD')) as start_week,
