identify duplicated “value” within the same field OR comparing to other database value, so that able to work around with some operations such as
1/ remove the particular record
2/ update another field in the same record
Remarks: understand tadabase is a database instead of a spreadsheet , just here to make a wish 
Hey @Black
I think having a more robust system to check for duplicate entries is a great idea, I’d be interested to hear about your use case.
In the meantime, some fields have a checkbox that will prevent values from being saved if they’re not unique (like the email field in the users table).
Additionally, you can use form validation to check if a record value is unique or not prior to submitting the form. That could help reduce duplicates.
