How do you find if a value is present in a table ref
I have a table Customers with a 1-n relation to contacts. The contact table contains the user field access.
How can I check if current user is one of the contacts defined in customers.contacts.access
To elaborate further. The idea is to be able to show if the current user is related to the customer.
Contacts - relates to Customers. Contains a field "access" that is of type "user".
Projects - relates to Customers
How can I show a field on a project that show if current user is related to the Customer?
Ive tried aggregated functions but theres only a few: first/last/concat/count -which doesnt bring me further.
I would think that I should make some sort of
select Customers.Contacts where access = user()
Or something that works with array?
As I understand it the select is doing a table lookup unlrelated to the current so in the example I made here it would also require adding a relation to which customer I need contacts from. maybe the more "correct" approach is to do something with the collection that is received.
If I in the formular reference Customers.Contacts.access and concat it it shows only the users related to this customer. But how do I query this ?
I found a solution. Please let me know if this is the optimal:
let ret := false;
for contact in Customers.Contacts.access do
if contact.User = user() then ret := true end
Do you tried one request like that ?
count(Custmer.Contacs.access where User = user())>0; => return true if count is > 0.
Thanks Jacques - that was much faster :-)
