[Numpy-discussion] query to array

Good afternoon,

The following works:

import pyodbc
import numpy as np

connection = pyodbc.connect('DSN=DSNname')
cursor = connection.cursor()
symbol = 'ibm'
request = "select to_days(Date), Close from price where symbol = '" +
symbol + "' and date > '2006-01-01'"
for row in cursor.execute(request):
    price.append([row[0], row[1]])
    priceArray = np.array(price)

Is there a better way to do this? Can fromiter be used?

Could this query result be put into a wider array from the start such
that columns 2... could be filled with calcs later?

Thanks in advance,

     jab

If you advance far enough, you arrive at the beginning.
