Hello, I have a problem using aggregate function in ACS.
When I add an additionnal data wich is based on the SUM() function in a simple query activity, I get a PostgreSQL Error : column "n1.irecipientid" must appear in the GROUP BY clause or be used in an aggregate function.
I can't do any aggregate, could you help me please.
Thanks for sharing the screenshots! Here are my comments:
I think you are using the avg function available in the 'Expression Editor'? Unfortunately, these Aggregate functions available in query editor are not quite efficient in the 'Additional data' section of query editor . Also, to fulfill your requirement there is no Group By function with Aggregate function here.
However, these Aggregate functions works quite well in 'Extract file' activity. You can use the Avg function in the output column section and the use Transfer file activity to export the data. I am not sure this works for you but I see this is only way to get the avg function work.
Pour un besoin similaire, j'ai configuré la même Query que toi. ça semble logique, mais j'ai pris le temps de comprendre pourquoi ça ne fonctionne pas, avant de trouver une solution de contournement que je partage volontiers en anglais :
The aggregate functions don't work with simple fields, only with collections :
The average profile age can be calculated by creating a Profile collection using Additional data in the main query and the Enrichment activity :
In your main query add as an additional data a constant text field labeled 'Collection Link' :
Add an Enrichment activity. In advanced Relations, Add an element with this definition :
Add new additional data with the profile collection we just created :
In the new window that pops up, go to Data and Create Element as follow :
Confirm all and run workflow. The field Avg(Age) should be added to Profile Collection.
