This project is no longer actively maintained and probably doesn't work with recent versions of Neo4j. PRs to fix aspects of its functionality are still welcome.

A Julia client for the Neo4j graph database.

Really easy to use, have a look at test/runtests.jl for the available methods.

c = Connection("localhost"; user="neo4j", password="neo4j")
tx = transaction(c)
tx("CREATE (n:Lang) SET n.name = \$name", "name" => "Julia")
tx("MATCH (n:Lang) RETURN n LIMIT {limit}", "limit" => 10)
results = commit(tx)

You can also submit a transaction to the server without committing it. This will return a result set but will keep the transaction open both on the client and server:

results = tx("MATCH (n) RETURN n"; submit=true)

Rollbacks are also supported:

rollback(tx)

If the goal is to simply run a MATCH query and get the result in the form of a DataFrames.DataFrame object, the cypherQuery function can be used. The cypherQuery implementation performs the query in a single transaction which automatically opens and closes the transaction:

results = cypherQuery(c, "MATCH (n) RETURN n.property AS Property")
