Neo4j

Dear Everyone,

Being that I am in europe, the system uses a "," instead on "."
I exported the data from Filemaker pro where in the fields uses commas to denote the decimal points.

How do I go about converting it so that Neo4J can import it? Is the a convert function in Neo4j?
Or is there a website like http://www.convertcsv.com/ that can just convert the decimal character?

Thank you in advance

Kind regards,
Jeffrey

You can use toFloat(replace(row.number, ',', '.'))

Hello Michael,

Thank you for that piece of information. It has been added and I am now at the following error.
It has to do with the url of the file on osx. Here is the url I get from terminal: /Volumes/Caldigit/Filemaker/Toys.csv

This gives the following error: Invalid url no protocol

Kind regards,
Jeffrey

put the file into the neo4j import directory and then use file:///Toys.csv

Hello Michael,

Thank you for that information. My question is. Do you know any good tutorials covering migrating a relational database with join tables over to Neo4J?

I have a database filled with join tables, and I want to bring it over.

Kind regards,
Jeffrey

Create a stored a stored procedure with all table joins. With JDBC connection to your database you can use call apoc.load.jdbc procedure with appropriate connection parameters and add exec stored procedure.

call apoc.load.jdbc('jdbc:sqlserver://localhost:1433;databaseName=vvv;user=bb;password=****','exec [dbo].[spname]')
yield row

I used this method to successfully import data from MS SQL server.

I recommend the neo4j-etl tool for this purpose

Neo4j

Load CSV - replace number with commas to dots ( 4,654 ---> 4.654)
