In today’s podcast episode you’ll be learning all about the aggregate functions that exist in SQL.
What the heck is an aggregate function? Well that’s what I’m going to try and teach you today, and I promise, it’s not a difficult concept to grasp. Just think of an aggregate function as a method that you’re calling that will process data in your database and return a value. Obviously the returned value will depend on which of the aggregate functions you choose to use.
So that begs an obvious question, what are the aggregate functions that we can use in SQL? I’m glad you asked, here’s the ones that I use all the time in MySQL:

MAX
MIN
SUM
AVG
COUNT

Okay, great! So now we know what the names of these functions are, now let’s see some examples of them in use!

Alex emphasizes the importance of understanding the fundamentals of coding and how it has impacted her personal growth and progress. In this conversation, Alex discusses her experience in the coding bootcamp and the challenges she faced. She shares how she overcame those challenges and gained confidence in her coding abilities. The conversation also explores the difficulty curve in learning programming and the importance of perseverance. Alex talks about her job search process and the need for relentless follow-up. The conversation concludes with an invitation for listeners to connect with Alex and seek advice on their own coding journey. Takeaways  Transitioning from a non-technical career to the tech industry is possible with the right support and guidance. Learning HTML and CSS is a great starting point for beginners in coding. Struggling with certain concepts is common in coding, and seeking help from instructors is crucial for overcoming challenges. Understanding the fundamentals of coding, such as methods and functions, is essential for building a strong foundation. Overcoming challenges in the bootcamp can lead to significant growth and improved coding skills. The difficulty curve in learning programming often means that the second half of the bootcamp is easier than the first half. Struggling on the job is different from struggling in the bootcamp, but both experiences can be valuable learning opportunities. Relentless follow-up in the job search process can significantly increase the chances of getting an interview. Revisiting assignments and focusing on mastering core skills can help improve coding abilities. Networking and interpersonal skills are just as important as coding skills in the job search process.
