mysql.connector - You have an error in your SQL syntax; near '%s' at line 1 [closed]

Question

I'm referencing this page in order to make a SELECT query to my database. However, I'm getting this error:

mysql.connector.errors.ProgrammingError: 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s' at line 1

Here's the section of code with the problem:

import mysql.connector
cnx = mysql.connector.connect(user='xxxx', password='yyyy',
                              host='zzzz.us-west-2.rds.amazonaws.com',
                              database='iiii')
cursor = cnx.cursor()

# ...

givenUsername = 'testUser123'
checkUserAuthQuery = ("SELECT password FROM UserAuth WHERE username = %s")
userAuthInfo = (givenUsername)
cursor.execute(checkUserAuthQuery, userAuthInfo)

# ...

Notes:
- When doing an INSERT query with %s it works.
- Also, replacing %s with 'testuser123' works.

Answer 1

You are missing the comma to make userAuthInfo a tuple. Change it to :

userAuthInfo = (givenUsername,)
