Returns a unique system identifier for the Snowflake session corresponding to the present connection.
This will generally be a system-generated alphanumeric string. It is NOT derived from the user name or user account.
Example
>>> # Return result is tied to session, so we only test if the result exists>>> result=session.create_dataframe([1]).select(current_session()).collect()>>> assertresult[0]['CURRENT_SESSION()']isnotNone
