在Neo4j中导入CSV文件

Question

使用此命令时 LOAD CSV FROM "file:///artists.csv" AS line CREATE (:Artist { name: line.Name, year: toInt(line.Year)})

我到了 错误：Type mismatch: expected Any, Map, Node or Relationship but was List<String> (line 2, column 25 (offset: 68)) "CREATE (:Artist { name: line.Name, year: toInt(line.Year)})"

CSV文件 "1","ABBA","1992" "2","Roxette","1986" "3","Europe","1979" "4","The Cardigans","1992"

Answer 1

您的CSV没有标题，因此您无法按名称访问列，即执行此操作时：line.Name。

您必须按列索引执行：line[0]

干杯

Answer 2

请尝试

从“ file：///artists.csv” AS行加载带有标题的CSV文件 创建（：艺术家{名称：line.Name，年份：toInt（line.Year）}）

确保atists.csv文件中具有“名称”和“年份”列
