this might be a stupid question but I'm new to neo4j.
I'm using the desktop version and from there I created a new database from a new project. I also can see it from the browser and I can see data and stuff.
But if I go on my terminal and run
cypher-shell
and from there I type
SHOW DATABASES;
I can only see the default dbs:
Does anyone know what I am doing wrong?
From the Neo4j desktop, you'll see the Start/Stop and Open buttons for a project database. Just to the right of these are 3-dots. Click on that and then open folder. This will get you to the various folders for the database. It's useful for seeing the size of the database, working with the config file, managing transaction logs, etc.

I'm using Neo4j Desktop Version 1.4.3. I've created a new project named "Yelp Project", then uploaded the yelp dump file in it, but I'm not getting the option "Create new DBMS from dump". So I selected Add --> Local DBMS and created a database. But when I open Neo4j Browser, there are no nodes and relationships. I'm not able to figure out how to get this done, can someone help refer image
The feature that you are looking for is not yet available for Neo4j desktop Windows version. See below community thread discussion then scroll at the bottom.

I am really sorry to ask a simple question like this, but it is getting frustrating. I installed neo4j 4.0.4 on my Windows machine, created a new project as shown in the official tutorial video and set a password for my local graph. Funnily, the tutorial video ends after setting the password and opening the browser not showing how to perform Cypher queries on this newly created database. In neo4j Desktop my database is shown correctly and it seems to be up and running.
However, when I try to connect to this database via the browser, I do not see the database at all. It is so confusing when connecting to the server to specify a username and password, if you only need to set a password for your database?! The default neo4j user can see the system and default database but not my project database. In addition, I cannot link files from the project directory in Cypher queries. I tried to disable authentication, but it did not help at all.
When I issue SHOW DATABASES command, it does not list my database as well.
Update / Edit:
Seems I misunderstood the concept of projects. Every database is named neo4j - default, regardless of the name specified in the project ?!. However, I still cannot access project files. So far, I copied the files manually in the database directory under "imports". But I guess that is not the intended way.
After importing data to this default database, it still shows no data in the project itself.
Data files in the imports directory are not automatically imported into the DB. That is because neo4j has no idea how you want to store that data as nodes and relationships.
So, it is up to you to determine your desired data model, and then write the appropriate code to enforce that data model.
You can take a look at this page to learn about how to import CSV data (probably the most commonly used import data format).
I recently upgraded to Neo4j 4.0.6. (Community Edition)
After upgrading my "old" Neo4j database the browser :sysinfo command (Chrome and Safari) doesn't show any information. It just displays the empty tables for Store Size, id Allocation etc.
All the tables and labels are shown as in Neo4j 3.x but no values are prompted. It doesn't matter if I change the "Use Database" settings (switch to system and back) or if stop and restart the server. No entries for :sysinfo show up.
Any idea how to reactivate the DB :sysinfo in the browser interface again is greatly appreciated.

I tend to think its an issue with recent versions.
It caused me to believe a multi upgrade store was incorrect.
So I went the long 'dump to cypher and reimport' route.
After node import, sysinfo was working (4.1 CE)
This behaviour appeared when I added relations
CALL db.schema.visualization() is broken too (no graph tab)
What a time loss, I tell you.
Wont count the days
Somewhere I read to reset the indexes, be sure btree was used.
No, it didnt work.
your next move is to file an issue
It seems ppl also have this issue since 3.5 w/ clusters

I'm using Debian 9.9 and the version of Neo4j is 4.0. I'm having problems creating a new database using the neo4j browser. The instruction I followed is this.
I have tried the following Cypher command:
create database myNewDatabase
However, an error pops up like this:
Neo.ClientError.Statement.NotSystemDatabaseError
Unsupported administration command: create database myNewDatabase
Please let me know what the error message means and how I can solve it. Thx in advance:-)
In v. 4 (release Feb. 2020) of the professional version of Neo4j, it's easy to create new databases. Documentation
In the community edition, it takes a hack:
1. Edit the file NEO4J_HOME\conf\neo4j.conf
2. Un-comment the line: dbms.default_database=neo4j
3. Change the neo4j to whatever database name you want for a new database. Note: names must have between 3 and 63 characters. For example: dbms.default_database=mydatabase
4. Save the file
5. (If applicable) Kill the database server, and close the browser window with the Neo4j UI
6. Start the neo4j server, and open a new browser window, pointed as usual to http://localhost:7474/
7. Both the old (default) database, "neo4j" and the one you just created will show up. However, attempting to switch between them causes an error. If a switch is desired, repeat the above steps starting from (3)
Note: the above steps will create a folder named mydatabase (or whatever name you used), in NEO4J_HOME\data\databases , and it will populate its contents.
I personally think that switching between databases is such a BASIC operation that Neo4j ought to make it easily accessible in the Community edition!
I think I've got the answer to my question. It turns out that my license (the community edition) is not supported for working with multiple databases. An alternative could be this.
I've just started to learn the Neo4j graphs db, i am a .net developer and i have downloaded the .net version also the sample MVC project for .net (hour ago), I manage to make the project run and playing with it. Upon playing with the Cyphers Console, somehow i cant find the data's from the sample, maybe the default database of the console is pointing to the default db, how do i move to the database that is created by my sample project. is there such thing as database/schema here just like in MSSql/MySQL that tables are grouped by database?
thanks for response.
Look at neo4j-server.properties in conf folder in your DB folder, and search for org.neo4j.server.database.location and make sure it's pointing to the output folder you just created..
