# Define POST variables
uname = request.POST['username']
passwd = request.POST['password']

# SQL query vulnerable to SQLi
sql = "SELECT id FROM users WHERE username='" + uname + "' AND password='" + passwd + "'"

# Execute the SQL statement
database.execute(sql)

password' OR 1=1  

شرط اول   and   شرط دوم =
نتیجه  or 1=1
چون 1=1 است 
همیشه شرط کوئری درست خواهد بود
