Is it possible to avoid duplicate values in a column?
Use case
When I add a new record to a Table, I want to make sure that the value of its primary column (type text) is different than the values of all other records
I have a CRM with four tables: Accounts, Contacts, Opportunities, and Pipelines.
I do not want to allow users to create a record (e.g. an new opportunity) whose first column is the same as an already existing record
