python - PyODBC execute stored procedure does not complete -

-

i have following code, , stored procedure used call several stored procedures. can run stored procedure , complete without issues in sql 2012. using python 3.3. 

cnxn = pyodbc.connect('driver={sql server};server=.\sqlexpress;database=mydatabase;trusted_connection=yes;') cursor = cnxn.cursor()  cnxn.timeout = 0 cnxn.autocommit = true  cursor.execute("""exec my_sp""")

the python code executing, have determined inserting numerous prints. did see other question regarding python waiting sp finish. tried adding 'time.sleep()' after execute, , varying time (up 120 seconds) no change. stored procedure appears partially executing, based on results. data suggests interrupting 1 of sub-stored procedures, yet fine when sp run query analyzer.

my best guess sql config related, lost in look.

any thoughts?

just follow up; have had limited success using time features located @ link below, , reducing level of nesting stored procedures.

at level calling in above, there 4 layers of nested sp's; pyodbc seems behave little better when have 3 layers or less. doesn't make lot of sense me, works.

make python wait stored procedure finish executing

any input on rationale behind appreciated.
