Custom maxId reset after 200
Hello,
i've set my records to automatically assign a custom record number +1 at each new record using the formula:
let t := this;
let maxId := max((select 'Storage Clients').'ID Pratica n.');
t.('ID Pratica n.' := maxId + 1)
I would need to know how i can set the maxId to rest after 200 records.
Thanks for ythe help!

or even reset at the end of the day would be a solution

One option could be to build the needed serial number by using the record reference number, the numeric part of the automatically created record identifier. I mean something like:
let n := number(Id) - 1;'ID Pratica n.' := 1 + n - floor(n / 200) * 200 -
thanks Alain for the reply.
i've set my inital formula in the TRIGGER ON CREATE section. Where should i set the formula you suggested?
not very handy with coding.... i would need to understand exactly how and where i should write this
Thanks!

It should work in the same place, Trigger on create. Another possibility would be to make "ID Pratica n." a formula field, defined as:
let n := number(Id) - 1;1 + n - floor(n / 200) * 200 -
LOOKS GREAT. THE ONLY PROBLEM IS THAT LINKING IT TO number(Id) if i delete the record because of errors during the filling procedure it jumps to the following record therfore i lose 1 record number
-
it acts with the same logic of Ninox Id Number..

Solutions based on the Ninox Id are robust, since it is guaranteed to be unique and never reused. But if you delete a record, its number is of course lost forever, per the non-reuse.
A less robust solution, but without missing numbers, would be to put this as the "Trigger on create" function definition:
let n := last((select Table1).'ID Pratica n.');'ID Pratica n.' := 1 + n - floor(n / 200) * 200It uses the "last" function instead of "max" but, since the records found by the "select" command are ordered by Id by default, it should work pretty reliably.

thanks Alain! I will give it a try
