Getting #rid while Update-Upsert in OrientDB without searching again - insert

Question

I am currently using OrientDB to build a graph model. I am using PyOrient to send commands for creating the nodes and edges.
Whenever I use INSERT command I get a list of things which includes #rid in return.
result = db.command("INSERT INTO CNID SET connected_id {0}".format(somevalue))
print result
OUTPUT: {'#CNID':{'connected_id': '10000'},'version':1,'rid':'#12:1221'}
However if I use the Update-Upsert command I only get one value as return which is not the #rid.
result = db.command("UPDATE CNID SET connected_id={0} UPSERT WHERE connected_id={0}".format(cn_value))
print result
OUTPUT: 1
I want to know is it possible to get #rid as well while doing UPDATE-UPSERT operation.

Answer 1

I created the following example in PyOrient:
Structure:
A useful method to retrieve the #rid from an UPDATE / UPSERT operation could be the usage of the RETURN AFTER $current syntax in your SQL command.
PyOrient Code:
import pyorient
db_name = 'Stack37308500'
print("Connecting to the server...")
client = pyorient.OrientDB("localhost",2424)
session_id = client.connect("root","root")
print("OK - sessionID: ",session_id,"\n")
if client.db_exists( db_name, pyorient.STORAGE_TYPE_PLOCAL ):
client.db_open(db_name, "root", "root")
result = client.command("UPDATE CNID SET connected_id = 20000 UPSERT RETURN AFTER $current.#rid WHERE connected_id = 20000")
for idx, val in enumerate(result):
print(val)
client.db_close()
By specifying $current.#rid you'll be able to retrieve the #rid of the resulting record (in this case a new record).
Code Output:
Connecting to the server...
OK - sessionID: 25
##12:1

You can also modify the query to retrieve the whole resulting record by use only $current without specifying #rid (in this case I updated the record #12:1).
Query:
UPDATE CNID SET connected_id = 30000 UPSERT RETURN AFTER $current WHERE connected_id = 20000
Code Output:
Connecting to the server...
OK - sessionID: 26
{'#CNID':{'connected_id': 30000},'version':2,'rid':'#12:1'}
Studio:
Hope it helps
