Hi.

        I've made a small stored procedure un PL/python. This procedure retrieve
python code from a row then execute it and calls a predefined function.
        Alls works well while no others functions are defined and called in the row
retrieved code; I mean when I define the row retrieved code like this :

def powar(x):
        return x*x

def make_transform(x,y):
        plpy.notice("viewed from make_transform : %s"%out)
        if x>2 and y >5:                
                return powar(x+y)
        else:
                return x+y

and when I execute the following python stored procedure:

CREATE OR REPLACE FUNCTION tarage(NUMERIC,NUMERIC) RETURNS NUMERIC AS'  
        qry = plpy.prepare("SELECT expression from fonctions where name = $1",
["text"])
        res = plpy.execute(qry,["transf(x,y)"])
        expression = res[0]["expression"]
        x=args[0]
        y=args[1]
        plpy.notice(expression)
        exec expression
        out = "%s"%dir()
        plpy.notice(out)
        b = make_transform(x,y)
        return b
'
LANGUAGE 'plpython';

Here is the output :

supervisor=# select tarage(4.0,2.0);
NOTICE:  ('\ndef powar(f):\n\treturn f*f\n\ndef make_transform(x,y):\n\tout =
"%s"%dir()\n\tplpy.notice("viewed from make_transform : %s"%out)\n\tif
x>2:\n\t\treturn powar(x)\n\telse:\n\t\treturn x+y\n',)
NOTICE:  ("['expression', 'make_transform', 'powar', 'qry', 'res', 'x',
'y']",)
NOTICE:  ("viewed from make_transform : ['x', 'y']",)
ERROR:  plpython: Call of function `tarage' failed.
exceptions.NameError: global name 'powar' is not defined




        Well, I tried to recreate the restricted execution env, in my python console
interpreter and I got the right result!

        So is there a way to get the whole things work (to make powar() visible from
make_transform())?

        Thanks in advance?
