Hey,
I'm trying to run a command to find out 10 clients and the companies they
work for. I've used a query like this:
match (c: Client)-[WORKS_FOR]-(co: Company) return c, co limit 10
However, it keeps returning Java heap space error. Neo4j is installed on a
vm with windows server 2012R2 Intel
Please start a new thread for this discussion.

I did. Do you have any new ideas on the current topic?

I cannot run this command. It returns invalid syntax. Only way I could run
it was
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/LOCATED_IN.csv AS
c
MATCH (client: Client { Id: toInt(c.Id)}), (city: City { Id:
toInt(c.CityId)})
Return count(*) Limit 100
Also, I think a skype call
sorry
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/LOCATED_IN.csv AS c
WITH c
LIMIT 100
MATCH (client: Client { Id: toInt(c.Id)}), (city: City { Id: toInt(c.CityId)})
Return count(*)

Hi,
I've tried with another file, which contains ClientdId and VerticalId. The
thing is, there are only 7 verticals and 11M clients, so there is an
obvious one-to-many relationship there.
When I run
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/Vertical.csv AS c
WITH c LIMIT 100
MATCH
For me it sounds as if there is a big cross product happening.
I.e. many Verticals with the same Id
What happens if you do:
MATCH (v:Vertical)
RETURN v.Id, count(*)

if they don't have a value for city id, do they then have empty columns there
still? like user-id,,
You probably want to filter these rows?
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/LOCATED_IN.csv AS c
WHERE coalesce(c.CitiId,)
...

in the file I only have 2 columns, one for client id, which is always not
null and CityId, which may be sometimes null. Should I export the records
from SQL database leaving out the columns that contain null values?

No you can just filter out the lines with no cityid
Did you run my suggested commands?
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/LOCATED_IN.csv AS c
MATCH (client: Client { Id: toInt(c.Id)})
RETURN count(*)
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/LOCATED_IN.csv
The first query returns 96 which is the number of rows in the file and
the second one returns Neo.DatabaseError.Statement.ExecutionFailure
probably because of the null values. But then I run the following command:
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/LOCATED_IN.csv AS c
Ok, cool and you have the indexes for both :City(Id) and :Client(Id) ?

Yes, I do. I keep getting Java heap space error now. I'm using 100 commit
size.

did you create an index on :Client(Id) and :City(Id)

Hi there,
I'm experimenting with Neo4j while benchmarking a bunch of NoSQL databases
for my graduation paper.
I'm using the web interface to populate the database. I've been able to
load the smaller tables from my SQL database and LOAD CSV works fine.
By small, I mean a few columns (4-5) and
I'd probably use a commit size in your case of 50k or 100k.
Try to use the neo4j-shell and not the web-interface.
Connect to neo4j using bin/neo4j-shell
Then run your commands ending with a semicolon.
Just curious: Your data is imported as one node per row? That's not really
a graph structure.
I've tried using the shell and I get the same results: nodes with no
properties.
I've created the csv file using MsSQL Server Export. Is it relevant?
About you curiosity: I figured I would import first the nodes, then the
relationships from the connection tables. Am I doing it wrong?
Thanks
Perhaps something with field or line terminators?
I assume it blows up the field separation.
Try to run:
LOAD CSV WITH HEADERS FROM file:/Users/pauld/Documents/Client.csv AS c
RETURN { Id: toInt(c.Id), FirstName: c.FirstName, LastName: c.Lastname,
Address: c.Address, ZipCode: toInt(c.ZipCode),
Well, for all properties it sets null values. The data is read well from
the file. Is it ok if I have NULL values in the file? Would that be a
problem?

Also, the properties are not in the same order as in the csv file..
