JavaScript Interface to Databases
This is an introduction to managing databases in ArangoDB from within JavaScript.
While being in an established connection to ArangoDB, the current
database can be changed explicity by using the db._useDatabase()
method. This will switch to the specified database (provided it
exists and the user can connect to it). From this point on, any
following actions in the same shell or connection will use the
specified database unless otherwise specified.
Note: if the database is changed, client drivers need to store the current database name on their side, too. This is because connections in ArangoDB do not contain any state information. All state information is contained in the HTTP request/response data.
Connecting to a specific database from arangosh is possible with
the above command after arangosh has been started, but it is also
possible to specify a database name when invoking arangosh.
For this purpose, use the command-line parameter --server.database,
e.g.
> arangosh --server.database test
Please note that commands, actions, scripts or AQL queries should never access multiple databases, even if they exist. The only intended and supported way in ArangoDB is to use one database at a time for a command, an action, a script or a query. Operations started in one database must not switch the database later and continue operating in another.
