Well it works under Browser Cypher. So it should be fin. But I changed it:
USING PERIODIC COMMIT 10000
LOAD CSV WITH HEADERS FROM "file:///C:/test/tls206_part01.txt" AS csvLine
CREATE (p:Person { person_id: toInt(csvLine.person_id), doc_std_name_id:
csvLine.doc_std_name_id , person_name: csvLine.person_name })
And still nothing happening. Another idea?
