I wanted to write a small query that gives me a list of nodes that don't have a specific relationship.
A quick google gives me results that suggest this solution:
match (p:Product) where not (p)-[:HAS_CATEGORY]->(:Category) return count(p)
This works and is simple enough, but it keeps giving me this warning:
This feature is deprecated and will be removed in future versions.
Coercion of list to boolean is deprecated. Please consider using 'NOT isEmpty(...)' instead.
I have been googling this warning but it leads me to no conclusion as to how my original query should be written.
In general I found it quite frustrating to find an answer, which is also the reason I came to the forum.
Either I do not know the right place to find these kind of things or either the documentation regarding these warnings is extremely lacking.
Thanks for reading this,
