LOAD distinct - Question

cosmicyes — Sat, 16 Nov 2024 03:07:08 GMT

Hello,

I am trying to load some data from a given csv-file.

Very simlified extract of the data:

I have the following requirements:

* if I filter for claim 4711 amount should be 2 (not 4)
* if I filter for claim 4711 the sum of cost should be 25
* if I filter for unit 10 sum of cost should be 25
* if I count the number of claims it should be 3 (not 4)

I already have the idea that in the LOAD I should use the keyword "distinct" - but I don´t know exactly how to do this.

Can anybody give me hints for the LOAD?

Thank you in advance!

Rainer

No you should not be using DISTINCT with the LOAD statement as you do want to load all the rows in the csv.

When you come to the front end of things in charts and tables you should be using DISTINCT in functions like Sum() and Count().

So a count of claims would be Count(DISTINCT claim) and in your example that would return 3.

Your requirements 1, 2 and 4 might be manageable with a distinct in the load or the UI expressions but not 3. I assume that you need some more logic to prepare all wanted results within a single table and/or to split the task into several tables.

something like that? What is the logic for unit? I can't understand it

Table1:
load
claim,
sum(amount) as amount,
sum(unit) as unit,
sum(cost) as cost
group by claim
;
LOAD * INLINE [
claim, amount, unit, cost
4711, 2, 10, 10
4711, 2, 11, 15
4712, 3, 10, 10
4713, 1, 12, 5
];

Wow, thank you all for your very helpful answers.
I think especially the answer of Lanlizgu will lead me to the right direction.
I´ll need some more testing and will mark an answer as solution asap.
But also I guess I´ll have some further questions 😉
