Say I have the following Cypher statement:
MERGE (a:Person {name: {value1}})-[r:KNOWS]->(b:Person {name: {value2}})
Do I need to check for NULL here if one or the other node isn't found (so I
am assuming it will be NULL)? If a and/or b are NULL is the MERGE (or
CREATE) smart enough not to create a relationship to NULL?
Thank you.
