[r rad]

Please, try to inspect this code:

def execute(self, query, params=None, connection=None, db=None):

# ~ print (query, params)

error = None

con = connection

if not connection:

con = self.connect()

cursor = con.cursor()

try:

if type(query) == list:

self.__execute_query_list(cursor, query)

else:

self.execute_query(cursor, query, params)

except Exception as x:

error = error_message(x)

finally:

if not connection:

con.commit()

con.close()

return error

from items.py v7.

Is it correct? I think, that follow try code is OK:

try:

self.execute_query(cursor, query, params)

con.commit()

except Exception as error:

con.rollback()

error = error_message(error)

finally:

if not connection:

con.close()

I think this is not the place to discuss the core Jam.py code. 
The proper channel is github issues. Which then is linked to a pull request.
This is documented btw: https://jampy-docs.readthedocs.io/projects/V7/en/latest/admin/customisation.html
You are more then welcome to submit patches which are tested. 

Even tests are documented: https://jampy-docs.readthedocs.io/projects/V7/en/latest/how_to/how_to_write_tests.html

The server code is also there for testing.
