unable to UPDATE, no errors, no update, what am I doing wrong?
I'm not able to do and update, there aren't any errors, the table doesn't get updated.
environment: server: Synology, MariaDB 10.3.24; destop: ubuntu 20, python3.8, mariadb-dev 10.3.29;
database, table websites: entry_id is int(11), auto_increment and primary key; url_base is varchar(255);
python3 code on desktop:
entry_id = 2
url_base = "example.com"
sql_update_website_url_base = ("UPDATE `websites` SET `url_base`=(?) WHERE `entry_id` = (?);")
sql_update_website_url_base_data = (url_base, entry_id)
connection = (..,autocommit = True) # this does connect
cursor = connection.cursor()
print("url_base: {}, entry_id: {}".format(url_base, entry_id))
response = cursor.execute(sql_update_website_url_base, sql_update_website_url_base_data)
print ("response: {}".format(response))
output:
url_base: 'example.com', entry_id: 2 response: None

It looks like parentheses shouldn't be around the question mark.
Also sql_update_website_url_base should be just a string. Semicolons aren't needed in programming queries either (except for more complicated defining triggers/stored procedures etc).
so:
sql_update_website_url_base = "UPDATE websites SET url_base= ? WHERE entry_id = ?"
