Sometimes, data processing is blocked and frustrating. If you are not a professional programmer or developer, learning unfamiliar fields such as Python or Java is not easy and there is not enough time. This is for those who only know Excel and SQL basics when it comes to frequently used things. This is the first part of the SQL query book that you can find and use when you need it.
Create a temporary table and SELECT with one SQL statement
Processing repetition/cycle/loop through join without WHERE clause
Four SQL Techniques for Creating Multiplication Tables
Generate a random number within a given range
Create N comma separated data
Row data to columns, column data to rows
Create a list of consecutive days over a period of time
The SQL closest to real life
Practice-based learning! 💫

I've been studying SQL diligently, but I don't know how or where to use it.
🤔
In this case, like this, in that case, like that. Is there a query that can be written like a formula?
Through the open source database MariaDB and HeidiSQL environment
Study SQL that's closer to real-world use cases!
I send my encouragement and support to those of you who have diligently studied various database environments and SQL. However, at some point, it seems like learning, experience, and even development have become separate processes. After learning the basics, we're told to pursue advanced studies, gain practical experience, and even challenge ourselves in new fields. It's never-ending, right?
It might be a good idea to pause for a moment. Put aside the countless programming languages and tools that claim to be more powerful, and instead, carefully examine your own work based on the SQL you've been learning and refining. Ask yourself, will your work truly shine when combined with new technologies? Will it open up new avenues?
This lecture doesn't cover new SQL syntax or new technologies. It simply uses the SQL you've been studying diligently in a slightly different way. It's not a big deal once you know it, but it might have been daunting before. I hope this will be an opportunity and time to pause and enjoy the cool breeze.

Q. Why should I learn?
Not every software developer needs to hear this, but anyone working with data should definitely listen.
Q. Will it be difficult for non-majors?
SQL isn't a major/non-major field. If you have the curiosity, a little skill, and a little effort, it's possible.
Q. To what extent do you explain?
The internal data transformation process leading to the result query is explained in an Excel table.
