使用 Python 中的 Sqlite3 模块更新表

Question

I am working on a project where i need to update the password column of a user table pointing userid as the primary key, whenever the user reset his/her password. I am passing username and password to update_table function based on the values entered by the user from console and below is my code snippet -

def sql_update_table(conn, username, reset_password):
    c = conn.cursor()
    #value = (username, reset_password)
    #c.execute('''UPDATE user SET password = ? WHERE userid = ? ''', value)
    c.execute('''UPDATE user SET password = reset_password WHERE userid = username''')
    conn.commit()

I tried both case passing values with a tuple as mentioned in # and directly as mentioned without a #. However, for first case, there is no error but the table is not getting updated with the new value of password and for later one i am getting below error -

sqlite3.OperationalError: no such column: reset_password

Please help me to solve this. Thanks in advance !

Can you please try replacing

c.execute('''UPDATE user SET password = reset_password WHERE userid = username''')

with

c.execute('''UPDATE user SET password = ? WHERE userid = ? ''', (username,reset_password))
