Single relationship constraint

[pritamkurunkar]

(nodeA)-[relation]->(nodeB),

In the above example, I want to restrict to have only one relation between instance of nodeA & nodeB.

How can this be done?

Thanks in advance.

Hi @pritamkurunkar - there is no constraint or other simple way to enforce this in the database itself. What is the use case that led you to this requirement?
