I am back developing futher our Python/CGI based web application run by
a Postgres DB
and as per usual I am having some issues. It Involves a lot of Legacy
code. All the actual
SQL Querys are stored in the .py files and run in the .cgi files. I
have the problem that I
need to construct a row from
I have been using a round command in a few places to round
a value to zero decimal places using the following format,
round('+value+', 0)
but this consistantly returns the rounded result of the value
to one decimal place with a zero
EG:
4.97 is returned as 5.0 when i want it returned as 5,

round returns a float. Use
int(round('+value+', 0))

Okay, I have been handed a python project and working through it I have
had to add a report. I am returning 10 variables the results of an SQL
Query
and as usual the number of results vary from 1 result to 10 results so
I
implemented a check to see if the array item was empty or not. The code
is
`historyRep` seems to be shorter than you think it is. Try printing it
too see what it actually contains.
Ciao,

HistoryRep is an array value so historyRep[0] to [7] all have values
in them but historyRep[8] and [9] do not as the query does not always
return a
Check with if history8 is not None. Won't help your problem, but it
is a bit more pythonic code ;-)

Actually i tried that as well when i was fooling around, atm i am less
concenred
with pythonic code and making it work in the first place. The entire
program to
be fair is a bit messy
Note: sometimes having a clean and readable program is better than
having a running program that you can't read, because you can fix the
the first one, and it can teach you something.

Thanks for your help and suggestions i'll give them a shot.

I need to call a function stored in Postgres which does a lot of the db
and calculation work
all the SQL queries are hardcoded in a file called cmi.py. What i need
to do is too to call
my function from postgres passing in my product_code variable into it
and returning the
value from the query into
I did do a google search i have looking through the one python book i
have
and there are plenty of references for how to write a function in
Python but
not as many on how to call a function stored in postgres using python I
have
tried the conn.execute(cmi_grn_cost(productCode)) and also the
11 matches
