- I believe it is in finally block where it might be throwing this error. You should update the post with the stacktrace with the line which is causing the issue – mad_ Commented Mar 20, 2019 at 18:22
- 2 You need to provide your full traceback for questions like this, since it's normally difficult to figure out where the error is otherwise. In this case though, it's likely because mysql.connector.connect(...) raises an exception and the mySQLConnection referenced in the finally clause is never assigned to. – thebjorn Commented Mar 20, 2019 at 18:23
- @AravinthDeep what mysql package are you using?? – Lord Elrond Commented Mar 20, 2019 at 18:31
- You should remove your personal credentials from the question and change them shortly after.. Additionally, as @thebjorn pointed out your connection attempt: mysql.connector.connect(....) probably failed and threw an exception so trying to close the variable, mySQLConnection, within your finally scope wouldn't make sense since instantiation failed. To safe guard against this simply check for the variable's existence with an: if mySQLConnection in your finally clause before trying to close the connection – Nathan Commented Mar 20, 2019 at 19:01
- @NathanWright that won't work, since the error happens before the assignment (first line inside try) happens, thus the variable doesn't even exist in the finally clause -- i.e. if mySQLConnection: will fail with the same error. It would work if the OP sets mySQLConnection = None before the try: – thebjorn Commented Mar 20, 2019 at 19:12

8. You only define conn and cursor inside the if block checking the form values. If the block is not entered, they're not defined, but you still try to reference them to close them anyway. You should only call close on both if you've defined them. Either move conn = and cursor = to before the if block, or move the close calls to within the block.

If conn.cursor () throws an exception, cur will never be assigned, thus the code in the finally block will be referencing cur before assignment. Try removing that try block and seeing what happens, its likely that conn.cursor () is throwing some kind of exception you'll need to sort out. answered Oct 22, 2014 at 0:56.
