Day 98 of 100 Days of Code & Scrum: SQL Sunday

#javascript #webdev #beginners #100daysofcode

Happy weekend, everyone!

Today, I spent most of the day learning MySQL. I dived deeper into various data types in SQL as well as their respective functions. Also, I learned about how logical operators in MySQL work, which isn't that different from how they work in other programming languages. One interesting thing I noticed is that string comparison in SQL is not case sensitive.

Anyway, let's move on to my daily report!

Yesterday

I practiced utilizing aggregate functions in MySQL and learned more about the Nexus framework.

Today

- CURTIME()
