cypher-shell | command line shell where you can execute Cypher

If the data is not consequent ( for eg. the size of the movies database ), you can export to cypher statements to the browser directly by specifying null for the file option value :

I'm running an EXPLAIN on this and seeing an Eager operator in the query plan, that basically cancels out the periodic commit and causes all results to manifest in memory, that's leading to the out of heap operation. The FOREACHes here are causing this, you won't be able to use this approach when using periodic commit.

Instead try using coalesce() to use the first non-null value, first attempting to get the row value, then use the node value:

When a breakpoint hit during debugging, the embedded server also stops responding.

If you want to look at the state of your DB during unit tests, you need to pause the execution without the breakpoint. My solution is not exactly what you want but you can try this

You can create multiple parameters with the correct types in a single :param command using "destructuring".

For example, to get d and x with the correct types:

The problem was solved by downgrading the version of Neo4J.

Version 4.0.1 uses a higher version of the bolt protocol, which isn't documented so far, and thus not used by neo4j-client.
Version 3.5 uses the old protocol (bolt version 1) and is thus compatible.

You must only use a semicolon at the end of a Cypher statement, not at the end of every clause.

A Cypher statement usually has a RETURN clause at the end, but it can also end with a clause that writes to the DB (e.g., a CREATE clause) if there is nothing that needs to be returned.

In your particular file, you really only have a single Cypher statement, so delete all the semicolons except the last one.

The answer is: you can't restart Neo4j through cypher.

What your options are if you use Neo4j as a Service:

• Windows aka (cd to the right directory) neo4j restart
• Linux aka systemctl restart neo4j

I had the same problem. I tried to set the initial password and it said The specified user 'neo4j' already exists. I had thought I had set the initial password earlier via the command line, but it didn't take because there were special characters in the password string.

What ended up working for me was opening up the Neo4j Browser and it prompted me for a password. I entered 'neo4j' and then it gave me the option to set a new password through the browser. Once I did that, it worked.

If you need to turn off auth_enabled to test something, make sure to remember to restart the server. sudo neo4j restart It can also take a few minutes to restart, so make sure it's fully up and running first. (And then, of course, don't forget to turn auth_enabled back on again.)

It also took me a few tries to get the configuration correct in the conf file at /etc/neo4j/neo4j.conf

I set dbms.connectors.default_listen_address=0.0.0.0

And dbms.connectors.default_advertised_address=your.webdomain.com

Also, this guide helped me with setting up a certificate for the neo4j browser endpoint. https://medium.com/neo4j/getting-certificates-for-neo4j-with-letsencrypt-a8d05c415bbd

Add the --format verbose flag to the command.
