Hello,
I'm using PL/Python in PostegreSQL 9.0.3 and Python 2.6.5, I want to use a
feature of Python 3, Python have an option to import a module from future
version of Python.
In my case, I want to use the Python 3 division module, because it returns a
float division of integers by defaut, which in Python 2.x only returns an
integer, then I need use division module of the Python 3.
So to import a module from a future version, simply:
from __future__ import modulename
In my case I'm importing the division:
from __future__ import division
Python must requires that the import be in the first line of code, then that is
my problem, e.g., when running the function below:
CREATE OR REPLACE FUNCTION test() RETURNS text AS $$
from __future__ import division
a = "8/5"
return eval(a)
$$ LANGUAGE plpython2u;
returns the following error:
SyntaxError: from __future__ imports must occur at the beginning of the file
But "from __future__ ..." is on first line of code.
Has anyone had this error? and what may be this error? a bug in PL/Python? How
can I fix this error?
Thanks,
Davi Duarte.
