(username).txt
and then on it the password?
likes this at :
link and this link
or like at this...
put in a .txt file and then dump like that way?
You have to externally encrypt your file.
As the resulting sql file is a text file. Use zip or rar to compress and cypher your data.
In more Detail for windows please search for other operating systems or other programs than 7zip
First make a backup
mysqldump --routines yourdatabase/schema > outputfile.sql
There are a lot of options, so check https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html
Now start for example 7zip File Manager
Select the nackup dile outputfile.sql
And click on add
This dialog appears
Give your new compressed file a name. enter a password.
Slect sfx if your are not shure, if 7zip is installed on the maschine where you have to restore your database
Winzip and winrar have their own methods.
There are of course solutions, which you can use at a command prompt. see https://dba.stackexchange.com/questions/5831/how-do-you-encrypt-data-while-performing-a-mysqldump
I have graph.db folder from neo4j. It contains lot of neostore*.* files. How do i export a csv file from this ?
Note: I have this graph.db sent from my friend.
Download and install Neo4j if you haven't already
Move the graph.db directory that you have now into the data/ directory of the fresh Neo4j installation, replacing the existing graph.db directory in the fresh Neo4j instance. (Note: If you are using the desktop Neo4j application you can simply choose the location of your existing graph.db directory when starting Neo4j).
Start Neo4j server
To generate CSVs you have a few options:
Export from Neo4j Browser With Neo4j running, open your web browser and navigate to http://localhost:7474. Execute a Cypher query. Click on the "Download" icon and choose "Export CSV" to download a CSV representation of the data returned. See screenshot below.
neo4j-shell-tools Use neo4j-shell-tools to export results of a Cypher query. Use -o file.csv to specify output should be written to CSV file.
See this blog post for more info.
I'm trying to import a csv file from the command line after connecting to my RDS database. Unfortunately I'm fairly new to the mysql command and file navigation commands. I'm looking to navigate to my directory where the csv I'm importing is located. This is the directory path ~/Desktop/images.csv. I know I use mysqlimport, but can't figure out the command to change directory
I have a scenario where there are two source file ABC.txt and DEF.txt. i want to make sure that if any files are present in that folder with naming convention as ABC.txt, it has to be moved to the different folder prior to loading to the SQL server, and the other (incorrect file) should be moved to a error log folder (separate folder). Can someone advice what task would i use to do that. i tried it using File system task but it just allow you to move or copy files from one location to other prior to loading the file.can someone advice how to i copy that incorrect file to the different folder ( error log folder)?
try to use a bat file.
move ABC.txt /directory
and after
xcopy "source" "destination_err\" /exclude:%temp%\ABC.txt /y
or you can use robocopy command in bat file, this is the command with parameters http://itsvista.com/2007/03/robocopy/
In a Windows environment, I'm trying to load a .csv file with statement:
LOAD CSV WITH HEADERS FROM "file:///E:/Neo4j/customers.csv" AS row
It seems not to work properly and returns:
Couldn't load the external resource at:
file:/E:/Neo4j/Customers.csv
Neo.TransientError.Statement.ExternalResourceFailure
What am I doing wrong? thanks in advance
I was getting this error on Community Edition 3.0.1 on Mac OS X 10.10
It appears that the LOAD CSV file:/// looks for files in a predefined directory. One would think that in the argument that one would give the Cypher statement the full path but that is not the case.
The file:/// - for my situation" meant that neo4j would append the given argument you gave to one that was already predefined and then go look for that combined path
The file:/// pre-defined directory directory did not exist entirely
/Users/User/Documents/Neo4j/default.graphdb/import, in my computers directory structure I was missing the "/import" folder, which was not created at install
To fix on my system, I created an "import" directory, put the file to be read in that directory. I executed the Cypher load statement I ONLY put the name of the file to be read in the file argument i.e.
LOAD CSV file:///data.csv
this worked for me.
It appears to be a security configuration. Here's the original answer I found: https://stackoverflow.com/a/37444571/327004
You can add the following setting in conf/neo4j.conf in order to bypass this :
dbms.security.allow_csv_import_from_file_urls=true
Or change the import directory dbms.directories.import=import
You can find the answer in the file
"C:\Users\Jack\AppData\Roaming\Neo4j Community Edition\neo4j.conf"
(above "dbms.directories.import=import")
For version neo4j-community_windows-x64_3_1_1 you have to comment out this line or you have to create the folder \import (which isn´t created through the installation) and add your file into the folder.
There it´s written that due to security reasons they only allow file load from the \Documents\Neo4j\default.graphdb\import folder
After commenting out on # dbms.directories.import=import , you can execute e.g. from
LOAD CSV FROM "file:///C:/Users/Jack/Documents/products.csv" AS row
In neo4j.conf I didn´t have to add/set
dbms.security.allow_csv_import_from_file_urls=true
On (Arch) Linux + neo4j-community-3.4.0-alpha09, edit $NEO4J_HOME/conf
/neo4j.conf:
uncomment or add: dbms.security.allow_csv_import_from_file_urls=true
comment: #dbms.directories.import=import
Restart neo4j (in terminal: neo4j restart), and reload the Neo4j Browser (http://localhost:7474/browser/) if you are using a web browser as your Neo4j interface/GUI.
Then, you should be able to load a csv from outside your $NEO4J_HOME/... directory
E.g.,
LOAD CSV WITH HEADERS FROM "file:///mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS ...
where my $NEO4J_HOME/ is /mnt/Vancouver/apps/neo4j/neo4j-community-3.4.0-alpha09/
LOAD CSV WITH HEADERS FROM "file:/mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS ...
also works, but not
LOAD CSV WITH HEADERS FROM "file://mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS...
or
LOAD CSV WITH HEADERS FROM "/mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS...
i.e. use ...file:/... or ...file:///...
It's probably an URL issue, try file:c:/path/to/data.csv
See my blog posts:
http://jexp.de/blog/2014/10/load-cvs-with-success/
http://jexp.de/blog/2014/06/load-csv-into-neo4j-quickly-and-successfully/
For the ubuntu system, I placed the file in /usr/lib/neo4j which helped me solved the issue. On every other location, i tried giving full permissions(777) but the problem remains the same. After going through another stackoverflow post, i realized that the file should be kept in neo4j directory.
In the Neo4j desktop select the database you are using, go to the setting and there you will find the solution... just comment the "dbms.directories.import=import" line
# This setting constrains all LOAD CSV import files to be under the import directory. Remove or comment it out to
# allow files to be loaded from anywhere in the filesystem; this introduces possible security problems. See the
# LOAD CSV section of the manual for details.
dbms.directories.import=import ### COMMENT THIS LINE
For macOS Mojave v 10.14.5
Actually, I had to uncomment dbms.directories.import=import from ~/Library/Application Support/Neo4j Desktop/Application/neo4jDatabases/database-e2dd2a9c-d450-4639-861b-1e7e42b56b31/installation-3.5.5/conf/neo4j.conf and restart the service. Then it worked. All files has to be placed in import directory.
Run command LOAD CSV WITH HEADERS FROM 'FILE:/<yourCSV>.csv' as l return l
I am using the Neo4j Desktop and as others have said, the default graph database has a predefined import location. You can find the location by using the UI. If you put the CSV into the import directory, then you can use the relative path directly from you load csv command
Neo4j version is 3.1.1, OS is win10.
For me, LOAD CSV would read from Neo4j_Database_Location/testDB/import/artists.csv.
At first, I put csv file on the path F:\code\java\helloworld\artists.csv, and my cypher sentence is
LOAD CSV FROM 'file:///F:\\code\\java\\helloworld\\artists.csv' AS line
CREATE(:Artist {name:line[1],year:toInt(line[2])})
Then I get the error message returned as follows:
Couldn't load the external resource at: file:/D:/Neo4j/db/testDB/import/code/java/helloworld/artists.csv
It means neo4j itself concat the file path.
"D:/Neo4j/db/testDB/import/" is the Neo4j database location, and the "code/java/helloworld/artists.csv" is the csv file location.
For example, I install Neo4j on the path D:\Neo4j\Neo4j CE 3.1.1, and database loaction is D:\Neo4j\db. I put the CSV file on the path D:\Neo4j\db\testDB\import\artist.csv. If you don't have the file folder "import" on the path, you should creat it by yourself and put your file in the folder "import".
Then, put your csv file in the path, and input cyper sentence:
LOAD CSV from 'file:///artist.csv' as LINE
CREATE(:Artist {name:line[1],year:toInt(line[2])})
In a word, once you put the CSV file in the right path, the problem can be solved.
Related explaination in the LOAD CSV developer-manal
If dbms.directories.import is set to the default value import, using the above URLs in LOAD CSV would read from /import/myfile.csv and import/myproject/myfile.csv respectively.
If it is set to /data/csv, using the above URLs in LOAD CSV would read from /data/csv/myfile.csv and /data/csv/myproject/myfile.csv respectively.
Set the Property "dbms.directories.import=import"
Create folder 'import' explicitly at "/Users/User/Documents/Neo4j/default.graphdb/" because pre-defined directory did not exist entirely
place the csv data set here in the import folder
then run the code like - LOAD CSV FROM "file:///C:/customers.csv" AS row
In addition after you run the line, you can analyze what is going wrong in the code section to get a better understanding
you put your dataset into the import directory in neo4j-community path.
Then re-run your command.
Add your csv file in the import folder of neo4j installation guide to do this.
open neo4j and start graph of ur project
then in open folders tab open import folders
Copy ur csv file in this folder
Copy that part in ur load syntax as file:///C:/neo4j_module_datasets/test.csv since ur neo4j in running
in C drive
Snapshot for your reference
Use the following syntax:
LOAD CSV WITH HEADERS FROM "file:///my_collection.csv" AS row CREATE (n:myCollection) SET n = row
If you are running a docker then, follow these commands before running above query:
docker run \
-p=7474:7474 \
-p=7687:7687 \
-v=$HOME/neo4j/data:/data \
-v=$HOME/neo4j/logs:/logs \
-v=$HOME/local_import_dir:/var/lib/neo4j/import \
neo4j:3.0
Then,
sudo cp my_collection.csv /home/bajju/local_import_dir/
One of the following should solve the LOAD CSV errors (assuming you have dbms.security.allow_csv_import_from_file_urls=true)
If using Linux check for the permissions for the file. Change it using chmod 777 file_name.csv
Check if the file format/format for the contents within the file is correct.
The easiest way (be ware of security) is to serve you directory over http and use the http import
in the command line go the folder where csv files are lcoated
run the following depending on your python env.
Python 2
$ python -m SimpleHTTPServer 8000
Python 3
$ python3 -m http.server 8000
- Now you can load your files from your local host
LOAD CSV FROM 'http://localhost:8000/mycsvfile.csv' AS row
return row
- you can actually expose files on one host and load them where your DB is running by exposing the folder and replacing localhost with your IP
