| Subject | Trying to work with data from a query using Python. |
| From | ethereal_robe@hotmail.com |
Hello, I'm working with PostgreSQL and Python to obtain 2 columns froma database and need to print it in a specific format.
Here is my current code.
#!/usr/bin/python
# -*- coding: utf-8 -*-
import psycopg2
import sys
con = None
try:
con = psycopg2.connect(database='DB', user='ME', password='1234')
cur = con.cursor()
cur.execute(" select Account_Invoice.amount_untaxed, right (Res_Partner.vat,length(Res_Partner.vat)-2) as RFC from Account_Invoice inner join Res_Partner on Account_Invoice.partner_id = Res_Partner.id inner join Account_Invoice_Tax on Account_Invoice.id = Account_Invoice_Tax.invoice_id where account_invoice.journal_id=2 and account_invoice.date_invoice >= '2013-01-01' and account_invoice.date_invoice <= '2013-02-01' and account_invoice.reconciled is TRUE and account_invoice_tax.account_id = 3237 and account_invoice.amount_tax >= 0;")
rows = cur.fetchall()
for row in rows:
print row
except psycopg2.DatabaseError, e:
print 'Error %s' % e
sys.exit(1)
finally:
if con:
con.close()
Now assume that fetchall would print the following:
LOEL910624ND5 from the column vat as RFC.
227 from the column amount_untaxed.
Now I would need to print that in the following format.
04|85|LOEL910624ND5|||||227|||||||||||||||
04 always goes in the first column and 85 always goes in the second, vat goes in the third and the amount_untaxed goes in the eight column but we still need to have 22 columns in total.
