I didn't expect much, but it was a great help. I had doubts about coding while creating and modifying database programs with hardcoding before. Then, while learning dapper and Entity Framework on my own, I was able to relieve my thirst by watching this lecture. Thank you. One thing I'm curious about is that when I post a database project, my PC mssql version is 2014 (it's a bit difficult to upgrade the version because it's for work), so I'm worried that I should give up halfway.
