I ran into problems, while trying to insert to database:

ur_psql.execute("""insert into smth(data, filedate, filedby)"""""" values('%s', NOW(), %s)""" % (data, userid))

where data=""" "5.09,448,1418112000"; d="scan'208" """(a string containing double and single quotes) Any ideas how to insert such string to db ? Thanks

You can read about it at: http://initd.org/psycopg/docs/usage.html#the-problem-with-the-query-parameters

Simply do not use quotes in SQL and instead of % string Python operator use 2nd parameter of execute() which is data you want to pass to SQL query:

sql = "insert into smth (data, filedate, filedby) values (%s, NOW(), %s)"
ur_psql.execute(sql, (data, userid))
