Python, mysql.connector Error: No Result Set to Fetch From; cgitb shows correct value being passed to function

Question

Allright this one\'s got me baffled so I decided to see if I could find a response on here, I\'ve searched up and down and several stackoverflow questions and answers and nothin

Answer 1

You're calling cursor.fetchall() twice. You shouldn't be doing that.

Change:

row = cursor.fetchall()
results = len(cursor.fetchall())
clientName, clientAddr, unLocker = row[1], row[2], row[3]

To:

rows = cursor.fetchall()
results = len(rows) 
if results > 0:
    row = rows[0]
    clientName, clientAddr, unLocker = row[1], row[2], row[3]

And while it doesn't have anything to do with your current problem, you should be using a parameterized query:

query = "SELECT * FROM sessionkeys WHERE clientName=?" 
cursor.execute(query, (value1,))
