unique subscription

Channelsupport 15 Sep, 2018

Hi, we have made a form in Chronoforms v5 with which people can subscribe for school.
The subscriptions are saved in a database.
How can we prevent that a person can subscribe twice?
Can we run a check in the database on one of the fields?
Any suggestions?
