Now it's just a very short-lived string in the Python program. Is there no exception? My inclination would be to go to the Python interpreter and try very simple interactions with the database. Create a table with only one column. Insert one value. See if the value is there. Hello, world. -- https://mail.python.org/mailman/listinfo/python-list

Please post your actual code. Cut and paste, don't retype. If there's an exception, post that, too. The source code of do_query_amazon() might be interesting, too. A commit() on the db cursor might do wonders. query = CREATE TABLE temp2 (ID int NOT NULL AUTO_INCREMENT, Enterprise_Value float, PRIMARY KEY(ID)); query = INSERT INTO TABLE temp2 (enterprise) VALUES(+ str(curObservation) +); As a general remark, don't build your queries like that, rely on the API to insert the values. E. g.: cursor = conn.cursor() cursor.execute(insert into table temp2 (enterprise) values (?);, (curObservation,)) (Some databases use '%s' instead of '?') do_query_amazon(conn, query) close_psql_amazon(conn) -- https://mail.python.org/mailman/listinfo/python-list

Is that really what you wanted to do? Most likely, you should be using a parameterized query here; are you familiar with that concept? You seem to have custom functions to do your database work here. Without knowing what those functions do, it's hard for us to advise further. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
