8.4. Interacting with MongoDB

CALL apoc.mongodb.get(host-or-port,db-or-null,collection-or-null,query-or-null,[compatibleValues=true|false],skip-or-null,limit-or-null) yield value

perform a find operation on mongodb collection

CALL apoc.mongodb.count(host-or-port,db-or-null,collection-or-null,query-or-null) yield value

perform a find operation on mongodb collection

CALL apoc.mongodb.first(host-or-port,db-or-null,collection-or-null,query-or-null,[compatibleValues=true|false]) yield value

perform a first operation on mongodb collection

CALL apoc.mongodb.find(host-or-port,db-or-null,collection-or-null,query-or-null,projection-or-null,sort-or-null,[compatibleValues=true|false],skip-or-null) yield value

perform a find,project,sort operation on mongodb collection

CALL apoc.mongodb.insert(host-or-port,db-or-null,collection-or-null,list-of-maps)

inserts the given documents into the mongodb collection

CALL apoc.mongodb.delete(host-or-port,db-or-null,collection-or-null,list-of-maps) yield value

deletes the given documents from the mongodb collection and returns the number of affected documents

CALL apoc.mongodb.update(host-or-port,db-or-null,collection-or-null,list-of-maps) yield value

updates the given documents from the mongodb collection and returns the number of affected documents

If your documents have date fields or any other type that can be automatically converted by Neo4j, you need to set compatibleValues to true. These values will be converted according to Jackson databind default mapping.

Copy these jars into the plugins directory:

You should be able to get them from here, and here (BSON) (via Download)

Or you get them locally from your gradle build of apoc.

gradle copyRuntimeLibs
cp lib/mongodb*.jar lib/bson*.jar $NEO4J_HOME/plugins/
CALL apoc.mongodb.first('mongodb://localhost:27017','test','test',{name:'testDocument'})

If you need automatic conversion of unpackable values then the cypher query will be: 

CALL apoc.mongodb.first('mongodb://localhost:27017','test','test',{name:'testDocument'},true)
