use MERGE instead of CREATE UNIQUE #41

Closed jayped007 closed 4 years ago

jayped007 commented 4 years ago

The "CREATE UNIQUE" CYPHER statement is no longer supported as of NEO4J 4.0.

It is replaced by the "MERGE" statement that is also supported in earlier versions of NEO4J such as NEO4J 3.x.

The code changes relate directly to replacing CREATE UNIQUE statements with MERGE statements.

This was successfully tested with NEO4J 4.0.3.
