使用neo4j-import工具导入数据时，我们可以指定属性的数据类型吗？

Question

I've imported lot of data using neo4j-import tool only to be useless as the default data type is string for all columns. I'm not able to perform any aggregations on data. However, I'm able to change the data type using update commands but this is a lot of overhead.

Is it possible specify data types importing data itself using neo4j-import tool?

Answer 1

You should be able to use toInt(), toFloat(), and toString(). If you need booleans, you can do a comparison to get a boolean output.

Ah, this is assuming that you have access to Cypher in the import.

If you're using the 2.2.0 (and probably 3?) import, you should be able to define the type in the header like so propertyName:int

See the property types part of the 2.2.0 import tool docs, and the CSV header format sections.
