Hi, i've installed pyqt4 + python2.5 in windows, and wrote a small script to
test ODBC access to
a MySQL table. The script is:

from PyQt4 import QtSql
import sys

db = QtSql.QSqlDatabase.addDatabase("QODBC")

if not db.open():
    txt = db.lastError().text()
    print unicode(txt)

qry = QtSql.QSqlQuery()
qry.exec_( "select id from mytable where id = 20" )

if qry.next():
    a = qry.value(0).toInt()
    print a

I run it and executes (it prints the value of a) but then the following
error appears:

the instruction at "0x00ea2acf" referenced memory at "0x01013f20". The
memory could not be "read".

What's the problem ? Any idea ?
