I'm trying to connect to remote mysql (MariaDB) database with some security options within flask app using db_url. Simplified test version:
...ANSWER
Answered 2022-Mar-22 at 18:11After lots of digging - the problem ended up being outdated version of remote database. After upgrade everything works as intended.
My understanding is TLS versions that was used on database was too insecure (non existent in %version% variables). After upgrade I got in the results:

These two queries are semantically identical, but one of them succeeds and the other one fails. The only difference is in the WHERE clause, where the two operands of the OR operator have been switched.
ANSWER
Answered 2022-Mar-14 at 06:42I think the problem lies in DefaultExecutionContext._init_statement classmethod.
QUESTION
I have a stored procedure stored (ha) in file stored_procedure.sql. If I open this file in a SQL editor software, I can define the procedure and call it in either Python or SQL. The procedure looks like:
ANSWER
Answered 2022-Mar-11 at 13:55DELIMITER is not an SQL statement. It is a command to help the MySQL shell avoid confusion about how to interpret ; when it can appear inside the stored procedure definition which is itself part of a CREATE PROCEDURE statement. When running a CREATE PROCEDURE statement outside of the shell, DELIMITER is not required (or valid).
This fails:

QUESTION
I'm trying to incorporate google-cloud-tasks Python client within my fastapi app. But it's giving me an import error like this:
ANSWER
Answered 2022-Feb-09 at 17:35After doing some more research online I realized that installation of some packages is missed due to some existing packages. This issue helped me realize I need to reorder the position of google-cloud-tasks in my requirements.txt. So what I did was pretty simple, created a new virtualenv installed google-cloud-tasks as my first package and then installed everything else and finally the problem is solved.
Long story short the issue is the order in which packages are installed and that's why some packages are getting missed.

For a project I need to make a change to existing code for supporting a MySQL connection using SSL certificates. The implemented package is mysql.connector and is heavily integrated in other parts of the source-code, so replacing it with pymysql isn't an option.

...ANSWER
Answered 2022-Jan-11 at 08:50I let it rest for a while and after new investigation I found the culprit. Apparently the package has been renamed from mysql-connector to mysql-connector-python. Since the error itself was incomplete it took manual inspection of the code to figure out that the latest version from pip3 wasn't actually the latest version.
QUESTION
I have created an AWS Aurora DB serverless publically available, and I am trying to connect to the DB using python. But I am unable to connect and I suspect the VPC.
Please suggest if I have to check anything else, also I have these below queries;
- Is AWS Aurora serverless with min configuration a free tire DB?
- My VPC while creating the DB is Public already, yet I am not able to connect so do I need to perform any additional configuration changes?
Code Snippets:
...ANSWER
Answered 2021-Dec-24 at 06:47Aurora serverless does not have public ip. Form docs.
You can't give an Aurora Serverless v1 DB cluster a public IP address. You can access an Aurora Serverless v1 DB cluster only from within a VPC.
Same for Aurora v2.
So you have to setup a VPN between your home/work network and your VPC, or use SSH tunneling through some ec2 instance bastion host.

Install PyMySQL
You can use PyMySQL like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
