sql server - How do you get output parameters from a stored procedure in Python?

Question

I've googled around a bit, but maybe I didn't put the correct magik incantation into the search box.

Does anyone know how to get output parameters from a stored procedure in Python? I'm using pymssql to call a stored procedure, and I'm not sure of the correct syntax to get the output parameter back. I don't think I can use any other db modules since I'm running this from a Linux box to connect to a mssql database on a MS Server.

import pymssql

con = pymssql.connect(host='xxxxx',user='xxxx',password='xxxxx',database='xxxxx')

cur = con.cursor()

query = "EXECUTE blah blah blah"

cur.execute(query)
con.commit()
con.close()

Answer 1

I'm not a python expert but after a brief perusing of the DB-API 2.0 I believe you should use the "callproc" method of the cursor like this:

cur.callproc('my_stored_proc', (first_param, second_param, an_out_param))

Then you'll have the result in the returned value (of the out param) in the "an_out_param" variable.
