Validation Rule to Confirm if Field Value Exists in DB Table

(This post was last modified: 01-12-2018, 09:10 PM by natanfelles. Edit Reason: Changed the term "check" to "confirm" )

The is_unique rule checks if a field already have a value to avoid duplicates.

What about a rule to confirm if a value exists in a table field?

That could be used to do relationship and validate for new rows that needs Foreign Keys.
