Execute a psql script within a Python script

See original GitHub issue

I would like to Insert JAX into the ‘team’ table inside the nfldb-update script i.e. psql -U nfldb -f C:\Python27\Insert_JAX.sql where Insert_JAX.sql is INSERT into team values('JAX','Jacksonville', 'Jaguars') Is this possible? And could someone help me with the correct syntax to do this?

Yep that should work. Remember to close the cursor and connection when you’re done with


I would also recommend moving the password into a .pgpass file(google it for configuration) for easier access and more security so you don’t litter your scripts with your db pass. Your connection string will then become conn = psycopg2.connect("host=localhost dbname=nfldb user=nfldb") You can query with

week = 5
cur.execute("""SELECT * FROM game WHERE week = %s LIMIT 5;""",(week,))
print cur.fetchall()

@andr3w321 seems to be closing the cursor and connection on its own. I get an error that they are already closed so I left it out. My authentication method is set to trust in the pg_hba.conf file so no password is needed. Currently my program downloads the stats of every game in progress every 10 seconds but I think a more efficient way would be to monitor ‘some_file’ for a change in the modified time, indicating a change in a game in progress (score, down, end of quarter, etc.) Just not sure which file would be the best one to monitor.
