🤔🧠 SQL, do we really need to learn it the hard way?

Put down the thick books and let's start learning what you can use right away.

I've been building experience working with databases across various projects for 20 years.
When I first learned SQL, I was the same way.
I was busy cramming concepts like normalization, transactions, indexes, and locks into my head after buying thick books.
Even though I wasn't trying to become a DBA.

But as time passed and I worked in practice, I realized.
What's really important for most people learning SQL is
properly mastering just 'one SELECT statement'.


😊 It's perfectly fine even if you're not a developer

SQL is not just a language for developers.
These days, marketers, planners, data analysts, and even entrepreneurs
the ability to directly query and understand the data they want is becoming increasingly important.

Even if it's not complex analysis or system design,
if I can directly extract and understand the data myself,
the accuracy and speed of my work changes completely.


👍Recommended for people like this

I can't extract the data I want with SQL, so I'm working around it with unnecessary code.
I eventually solved it with a for loop, but it left me feeling unsettled as a backend developer / web developer

I have a lot of data but don't know how to extract it.
Non-developers / Planners / Marketers who have only worked with data using Google Sheets or Excel

SQL syntax, I learned it before but never really used it properly.
I've heard of SELECT, WHERE, GROUP BY and such, but it was difficult to touch in actual work for beginners / workplace novices
