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

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!


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



  • I learned about more datatypes in SQL and their use cases such as CHAR, DECIMAL, FLOAT, DOUBLE, DATE, TIME, DATETIME, and TIMESTAMP.
  • practiced various DATETIME utility functions such as:
    • NOW()
    • CURDATE()
    • CURTIME()
    • DAY
    • DATE_ADD
    • DATE_SUB and more...
  • learned about logical operators in MySQL, the common ones and interesting ones like BETWEEN, LIKE, IN, and more.
  • practiced using CASE statements for conditionally returning different values based on conditions.
  • continued Colt Steele's MySQL course.


Thank you for reading! Have a good day!
