How is the easiest way to to find the customer.id of the new
customers so I can insert the projectinfos?
It is easy to select rows not related with another table. One of the
following queries can be used.
Select * from "customers" where id not in (select "customerId" from
"projectinfos")
I'm sorry I wasn't clear enough describing the scenario.
Lets's say there were already 1000 records in the customers table.
Now I add 357 new customers to this table.
If I use one of your queries I'd get all 1357 entries of customers since
"project_x.projectinfos" would be newly created for this project and
therefor empty.
I need to know which customers.id was created for which line in the
temporary table that I read in with copy.
When I have those ids I can fill "project_x.projectinfos" with just
those new 357 customer.ids and foreign keys refering the new lookup-tables.
