Hi evrybody,

I need your help please ! I am not a developer but i am very motivated to learn,

I have 2 tables, one for order and one for orderdetails.

Order :

OrderNum

250400

250410

250420

250430

Detail order :
OrderNum	Product	Quantity	Price
250400	123	1	10
250400	650	5	8
250400	210	3	14
250410	137	9	10
250410	123	7	10
250410	159	5	10
250410	110	9	17
250410	201	4	12
250420	650	8	8
250420	210	10	14
250430	137	6	12
250430	123	3	10
250430	159	8	15

if in an order i have the product 650 i want to add for each line of the concern order : Contain650

it shoud be

Order :
OrderNum	Contain650
250400	1
250410	0
250420	1
250430	0

to try to do that i wrote :

left join(Order)
load *,
if(
Product='650', 1,0) as Contain650;

Load
OrderNum
Product
resident Detail Order

but the result is wrong , i have :

Order :
OrderNum	Contain650
250400	0
250400	1
250410	0
250420	0
250420	1
250430	0

i have 0 and 1 for each order, i don't understand why, can someone help me please ?

Many thanks

This is because the original table is broken out by Product.
Just because you have omitted Product in the final table, it will not do a group by.

You will be fine if you leave Product column in final resulting in-memory table.

In the Qlik front-end, it will do the group by for you when you create a table of OrderNum | sum(Contains650)

thanks for your answer, but when i write load *, it includes Product, no ?

left join(Order)
load *,
if(
Product='650', 1,0) as Contain650;

Load
OrderNum
Product
resident Detail Order

left join(Order)
*load ,**
if(
Product='650', 1,0) as Contain650;

Load
OrderNum
Product
resident Detail Order

Is this table you have in the data model or a table created in a sheet?

Order :
OrderNum	Contain650
250400	0
250400	1
250410	0
250420	0
250420	1
250430	0

If you have OrderNum as a dimension, and sum(Contain650) as a measure, you will have your intended result of

Order :
OrderNum	Contain650
250400	1
250410	0
250420	1
250430	0

In fact my objective is to have 1 in my order table if i have a product 650 in an order detail

If you add this to the script, your in-memory fact table should produce your wanted results:

Load

OrderNum,

sum(Contain650)

Resident Order

group by OrderNum;

The only reason you see duplicates in your current result set is because a join is a Cartesian product, and the join conditions are a little ambiguous 🙂

i had created the case in excel.

in reality :

if i have the prestation ct21.1210 i want to change the admission type from AMBU to CONS... i have two times the lines and always keep my ambu admission type

Re: Help please

QlikTonic — Fri, 10 May 2019 23:08:30 GMT

this is like duplicated... the old and the new 😞

I see, I see.

In this case you don't need to do a join at all. You want to modify the fact table based on condition Prestation = 'CT21.1210'

If you just do:

Load

if(Prestation = 'CT21.1210', 'CONS', Type admission) as Type admission,

your other stuff

RESIDENT TableName

you will change AMBU to CONS if Prestation is CT21.1210.

No duplicates 🙂 🙂 🙂 No joins needed

) as ADMCode,
Resident Sejour_serviceTemp;
