Please, could you tell me if NOCODB has a type of field that permit to include data without repeat the data already has been included.
I mean, imagine you are introducing a new invoice number and by mistake you entry a data that already is in database. In this case you going to have two invoices with the same number. This case not has sense duplicate data. Only one number is needed per invoice.
What I want is a field that does not allow the repetition of its content, such as invoice number, Social Security ID, passport number, etc.
yes, the format of the field that does not allow repetition of content (data); that has already been included in the database can be variable(free). The important thing is that it does not allow the same data to be repeated.
Example, product code, invoice number, a person’s identification document number, etc.
