Hi,
I am using NDB_MONGODB to ask some questions to a database.
My database structure is pretty heavy, so I like to return as little data as
required to Kamailio.
I have tried the following MongoDB syntax for projection to include only given
(my_field) column in the response.
mongodb_find_one("srv_name", "database", "collection", "{ \"user_id\" :
\"$var(user_id)\" }, { \"my_field\" : 1}", "mgr1")
I always get full DB entry back. Is this supported?
The same string works OK in the vanilla mongo client.
How can I limit the result?
Thanks
Lars
