Can I learn Python while practicing writing queries for SQL simultaneously? I've recently completed learning SQL and trying to get better at it.
You can practice both by using https://www.psycopg.org from your Python code to communicate with your database. When I wanted to practice some SQL, that's what I did (we use psycopg at work, so that's what I practiced with, making a dream journal thingy for myself that was better than just noting stuff in a notepad because I could then look up e.g. what other stuff was correlated with Y, how many times I dreamed of X, etc. etc.)

Uploading CSVs to a SQL table using Python
If you're using Postgres for your SQL, look at the "copy' method of the psycopg module (see https://www.psycopg.org/articles/2020/11/15/psycopg3-copy/) . It's much faster than INSERTs in my experience (YMMV).

Underappreciated Challenges with Python Packaging
Back when I used Psycopg2, there was no -binary package, so you'd get libpq set up similarly to pg-native. Docs say:
> The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.
Relevant GitHub discussion: https://github.com/psycopg/psycopg2/issues/674
I dunno, this seems worse to me.

Automating Enhanced Due Diligence in Regulated Applications
The initial data collection is usually done through a web-based application where compliance teams input client or vendor information. Once a record is created, you can use ETL tools like Apache Hop to extract data from multiple sources (like financial records, regulatory filings, and public databases) in real time and store them in scalable databases like PostgreSQL or MongoDB for easy access and management.

MySQL vs. PostgreSQL: A Deep Dive to Find Out Which is Best
PostgreSQL and MySQL are two of the most popular databases offered by the open-source community. Both are Relational Database Management Systems (RDBMS), but PostgreSQL emphasizes SQL standard compliance, extensibility, and data integrity, while MySQL is known for its high performance, ease of use, and high concurrency for read and write operations. Choosing the right database is crucial for developers. So, how do you choose between MySQL and PostgreSQL? This article will provide a clear explanation.
