This is my first question on stackoverflow!
I'm currently programming a steamcommunity crawler, which crawls through the steam profiles and saves things like owned games, steamname, friends, ...
But when I try to run the insert command it just does NOTHING.

```
 if not self.check_user('games', id):
  print "insert"
  self.cursor.execute("INSERT INTO games (userid) VALUES(%s);" % id)

```

The program displays "insert" but the execute command does neither throw an exception, nor inserts something to the database.
In addition, an eventualy happening exception is not caught. When I forexample change the query towards "INSERT INTO games (useridd)", the program quits and I see the exception.

The application is multithreaded but acquired before executing, so I can't see any issue in that.
