'No duplicate entries' validation option

Uniqueness validation is very important for any database software. We've added no duplicates validation on Forms menu. This way you can avoid same information in one column

No Duplicates option allows you to validate data uniqueness. Please, see below a simple example of how to use this validation option.


1) Create a project with form.

3) Add just one field to the new form - "ID Number" with a Single line type

4) Find link Validation on Edit field page and click on it. Check No duplicate entries option and click submit. See screenshot below:


No duplicate entries  validation



Then add a new entry with any value, for example '1'. If you'll try to enter another record with same '1' value you will see error message.

This field has validation 'No duplicates', so you can add only one original record to the database.
