Clob reading in python using cx_oracle - not working
I am trying to fetch a clob data from Oracle server and the connection is made through ssh tunnel.
When I tried to run the following code:
(id,clob) = cursor.fetchone()
print('one fetched')
clob_data = clob.read()
print(clob_data)
the execution freezes
Can someone help me with what's wrong here because I have referred to cx_oracle docs and the example code is just the same.
python ssh cx-oracle

It is possible that there is a round trip taking place that is not being handled properly by the cx_Oracle driver. Please create an issue here (https://github.com/oracle/python-cx_Oracle/issues) with a few more details such as platform, Python version, Oracle database/client version, etc.
You can probably work around the issue, however, by simply returning the CLOBs as strings as can be seen in this sample: https://github.com/oracle/python-cx_Oracle/blob/master/samples/ReturnLobsAsStrings.py.
