Oh I see. You're trying to set a variable in the current module's
global namespace. There's two ways to do this, the first one is cleaner
and preferred:
1. Have a function in DatabaseAccess return the cursor then then set it
to a name in code that runs at the module level.
2. use the "global" keyword in the method:
def mymethod(self):
global blah
blah = something
Then your module has has blah in it's global method now. If you want to
stick a variable in another method's global namespace, as long as you've
imported it you just go:
module.newvariable = something
