I'm trying to subtract a value in one field from a value in another table, depending on ID number using Filemaker Pro 19.x. I thought I'd done this before without any problems but now it isn't working and I don't know why.
First, I want to do this in a calculation field, not in a script. I don't understand scripting at all and use it only when there is no alternative. In this case, I think a calculation field should work.
I have 2 tables, I'll call them "Data" and "Categories"
Both tables have the field "CID" "Category ID".
The CID fields in both tables are linked in the Relationship Editor
The Data table has a field "Product ID"
The Categories table has several fields related to products. Two of those are "MIN PID" and "MAX PID". These are the minimum and maximum product ID numbers.
Product IDs are assigned in ranges. If it is within a certain range, it has to belong to a certain category. These categories have CID numbers.
To assign the CID number to the products listed on the Data table, I did run a script that essentially recreated all the data within the Categories table. It was inefficient (in my eyes) because the data was sitting right there in the table. I couldn't figure out how to reference it, so I gave up and ran the script instead. The other problem is that if the CID ever changes for a product, I have to rerun the script (or someone else, who might not know about the script)
That said, I now have the correct CID assigned for all 62 product categories. What I want to do now is to use the CID MIN and CID MAX values (among others) in calculation fields in the Data table.
For instance, if the product ID is "45,001", it belongs to the Category "16", which has a MIN value of "30,000" and a MAX value of "50,000". I want to subtract the "30,000" from the "45,001", (PID - CID MIN) to return the result "15,001". This allows me to locate a product within the category. Instead of being "Product 45,001", it will be "Product 16.15001".
The calculation I tried is:
If (CID = CID::CID ; PID - CID::CID MIN)
The result is a huge group of records where this field is empty.
I also tried:
PID - CID::CID MIN
Again, no results.
Both tables have the field "CID"
The two CID fields are linked in the relationship editor.
I have tried this with a test file and it works perfectly. It does not work in the database I am working within.
What am I doing wrong?

I want alert when i am fetching two different item in the oracle query
basically i want to check what ever i am searching it should from one policy when every i any getting two different policy i should get alert or some remark in another query that more then one item got fetch
for example
when i am fetching the data from oracle using the query i want the single item in the column and if i get multiple item i should get the alert
select * from table policy_id in ('100')
By asking, "when do I get 2 different items", or "when I have two distinct values" for a given key, you must aggregate rows in order to compute an aggregate value. COUNT, SUM, MIN, MAX, AVG, STDDEV, etc... are all aggregate functions that operate on multiple rows. But for them to operate on multiple rows, you must raise the granularity of your data to a higher level, or what we call "group by". Group by the key column(s) and aggregate across your fact columns to summarize those facts within those groups.
In your case, group by the columns for which you want to see unique values in separate rows. Then count how many rows were included in each group by using the COUNT(*) function. You may then wrap the output of that in a CASE or DECODE to conditionally test that output and return something different based on that output. In my example, test for 1, otherwise if more than one, you have multiple rows sharing the same key values. DECODE arguments are (test value, comparison value, result-if-true, result-if-false). So below will show "multiple policies" if there are 2 or more rows with the same policy,claim, req values, and NULL/empty if there are not.
SELECT policy,claim,req,DECODE(COUNT(*),1,NULL,'multiple policies') alert
FROM table
WHERE policyid = 100
GROUP BY policy,claim,req
I have a table that shows the recurrence of purchasing a product, with the columns: product_id, report_date, quantity.
I need to list in a table the products that are more than 50 days unsold. The opposite I managed to do (list those that were sold in the last 50 days) but the opposite logic has not yet been able to implement.
Does anyone have any tips?
An example of the table:
product_id,date,report_date,quantity
329,2019-01-02 08:19:17,2019-01-02 14:34:12,6

There are many steps to do this task. I assume the date column is the one to work with. Your example from table includes duplicated entries. Is it right that at the same time the order is there twice?
So here are the steps:
At first add an calculated field date_past to your dataset:
DATE_DIFF(CURRENT_DATE(),date)
To the dataset add a filter SO_demo with:
include date_past<30
Then blend the data with it self. Use product_id as Join key. Only the 2nd dataset has the SO_demo filter. Add to the dimension of this dataset the calculated field sold_last_30_days with the formula "yes".
In the table/chart to display add a filter on the field include sold_last_30_days is Null.
While using Power BI for a few months now, we (the user group) encountered an issue that is not really clear to us.
We use Power-BI with a remote SQL-Server data source, we access the data source through direct query.
Let's pretend we have 2 Tables as below-
Table name: Issue
Column:
ResolutionTime(Date/Time)
IssueID(Unique Numbers)
Table Name: WorkItem
Column:
start (Date/Time)
end (Date/Time)
IssueID (Unique Numbers, Foreign Key to "Issue" table)
Table WorkItem also contain a calculated column "WorkTime" which uses this DAX-expression as below-
WorkTime = WorkItem[end] - WorkItem[start]
The two tables are configured through Power-Bi having a two-way 1:n relationship that can be queried to collect all "WorkItem"(s) assigned to an "Issue" entry, using the "IssueID" as correlation column.
To be able to compute the aggregated "work-time" for each "WorkItem", we use a new/calculated table with the following DAX expression to aggregate the total amount of time invested for a single "Issue":
SumWork =
SUMMARIZE(
WorkItem, WorkItem[IssueID], "All work per item", SUM(WorkItem[WorkTime])
)
The above table computes the total invested work-time for a particular issue, grouping/summarizing results based on the "IssueID" foreign key. This new calculated table is also configured to have a relationship with the "Issue" table, this time a "1:1" relationship, using the IssueID as correlation column.
Now to compute the time that the issue was worked on + the time for Resolution should be summarized in a calculated column inside "Issue", but this does not work:
ResolutionAndWorkTime = Issue[ResolutionTime] + SumWork["All work per item"]
But the above DAX expression fails to compile, as it always reports that it returns "more than one result", thus not being a singular result. But that is suprising, as the two table ("Issue" and "SumWork" are related to each other with a "1:1" relationship).
Tables:
Issues
IssueID ResolutionTime ResolutionAndWorkTime
1 03:20:20 ???
2 01:20:20 ???
3 00:20:20 ???
WorkItem
IssueID start end WorkTime
1 1-2-2020 3:20:20 1-2-2020 3:25:20 00:05:00
1 2-2-2020 6:20:20 2-2-2020 7:20:20 01:00:00
3 1-3-2020 3:20:20 1-3-2020 3:29:20 00:09:00
Any ideas what to look for? Data-types? Table-definition? Table-relationships? We checked other Stackoverflow questions/answers, but no good ideas retrieved so far.
NOTE that a lot of join/merge features of Power BI are not available if direct-query is used and thus joining the tables is not really an option (we think).
You need this following code for your new Calculated column.
Visit HERE To know more about RELATED.
ResolutionAndWorkTime = Issues[ResolutionTime] + RELATED(SumWork[All work per item])
Based on input provided by "mkRabbani" (see other answer) we investigated why "RELATED" does not function as expected. The problem originates in the access to the database. As suspected earlier the function delivers the expected results once the database access is switched to "import" instead of "direct-query".
As a workaround we now joins the data inside the SQL server by using traditional database views. Of course this only works for scenarios where the database is under control of the data analytics team.
I am new to SQL and Stack overflow and have a question about SQL Server syntax. i have searched online but I am not finding what I need and I would appreciate your assistance in this matter.
I have data in a source table for meal orders (each with a specific ID (e.g. 12345C) and items of each order (e.g. sandwich, drink, chips), each with an associated number starting with 1. For instance, the sandwich would have an item number of 1, the chips would be item # 2, and the drink would be item # 3 for the same orderID 12345C. The prior example would therefore have 3 rows of data in the source table for orderID 12345C.
My questions are these:
how do I use a SQL expression to determine the number of items per each order (e.g. 3 for the above example, which is also the maximum value for item number for each orderID)
and then add all of these items per order across hundreds of orders per day to determine the daily total number of items ordered.
So, if I had 3 orders in one day - one with 2 items, the second with 3 items, and the third with 4 items, I would like my final number to be 9.
This number is for use in a Sisense dashboard that allows SQL syntax in the field definition. Thank you for your help!
It is a bit difficult to explain but I am not able to use a query from a table because I am working with a dashboard in Sisense so I am adding fields in a pivot display and one of the fields I would like to include is the total count of order items per day (across several dozen orderIDs).
Here is an example of the data in the table: from the example I would like the final answer for orderID 1787588 to be 3 (there are 3 items within the order).
I'm working on a SSAS cube to allow user to analyze some sales.
So, I created a fact table to record all sales and few dimensions to browse inside data (category / location & store, etc...).
This is a example of the fact table output (from SQL Server Management Studio) :
When I browse my cube, I can review all sales including date, quantity, etc.
However, when I add some fields like the "unit price" or the "unit cost", it returns me a strange result probably due to an aggregate behavior.
It seems it return the sum of all matching rows (aggregateFunction property).
How to simply display the unit price of a sale without apply any calculation to the unit price column. The None value for the AttributeFunction display BLANK/NULL.
If your unitCost and unitPrice are the same for each product (I mean unitCost can be only 77.6 for product_id = 2), you can just use average (or even emulate average by SUM/COUNT) - but only for product dimension on axis!
Another dimensions will show real average values.
Maybe it's better to use this 'static' fields like attribute properties in 'Product' dimension? But you still need to add some logic to choose one value for several (or all) product members selected.
