ODatabaseDocument - query()
This method executes idempotent OrientDB SQL queries.
Querying the Database
OrientDB makes a distinction between idempotent queries that read data from the database and non-idempotent commands that modify the records. Using this method you can retrieve and operate on result-sets from OrientDB.
In the event that you need to execute a non-idempotent command on the database, see the command()
method.
