i am trying to search for a way to import database from sql server to neo4j. I searched for a way if exist but i didn't find what i want. My case is : database contains many tables so i want to bring them to neo4j in one click ( if exist ) using a tools or writing dotnet program
There is no 'one-click' solution - but you said you're happy to write some code, so -- here we go!
Neo4j can import via JDBC, via a set of procedures called APOC (https://neo4j-contrib.github.io/neo4j-apoc-procedures/#_load_jdbc). To do this, you'll need the SQL Server JDBC driver (https://learn.microsoft.com/en-us/sql/connect/jdbc/microsoft-jdbc-driver-for-sql-server?view=sql-server-2017).
And here (https://tbgraph.wordpress.com/2017/07/24/neo4j-apoc-load-jdbc/) is a blog describing the process, so that should get you all up and running!
I have referred to "how to import csv data in neo4j DB". However, all of them refer the standalone DB.
I created a Blank Sandbox on neo4j browser (not standalone) and trying to import from the local Windows machine with the guidelines given in Neo4j documentation as below.
LOAD CSV WITH HEADERS FROM 'file:C:/San/MyGraphData_CSV.csv' as row
RETURN row.columName;
I get Error " Neo.DatabaseError.General.UnknownError: URI is not hierarchical
".
The solutions earlier recommended to replace C:/ with C:/// and other, seems to refer the Standby Neo4j. But i am using online Sandbox and importing.
Please help me resolve as this is POC and I need to evaluate more features and go for the concrete neo4j installation

File URIs should begin with "file:///".
The 3 slashes do not go after the Windows drive letter.
I'm working on a solution to browse the database of Niagara database from a Delphi client application and I'm trying to find a way to access the database.
I appears oBix and SOAP is available. (I know abs. nothing about oBix!)
I'm completely new to this Niagara platform and to SOAP.
I'm trying to use SOAP and use Delphi WSDL import, but it fails with an error about invalid characters in line 23.
This is what I try to import.

Does anyone have a clue on why it fails or what am I doing wrong?
I tried another import http://www.webservicex.net/WeatherForecast.asmx?WSDL - that works fine.
viTables only seems to work with python 2.5. I have downloaded HDFView, but when I try to open a table I created following this tutorial, I get the following error message:
Failed to open file C:\tutorial.h5
java.io.IOException: Unsupported fileformat - C:\tutorial.h5
Any ideas for getting HDFView to work?
Is there something I need to do when I'm using pyTables from python to make the format more generic?
Any other good HDF viewers?
Btw, I've just discovered PyTables, and I'm really excited about it.
ViTables works for me with python 2.6 on windows. It is supposed also to work with 2.7.
However the version on the official site did not work for me and crashed. In a mailinglist posting I found the link to the berlios ftp server where I got a version that works like a charm.
Have you seen ViTables?
