Practicing SQL to enhance my skill #sqlpractice #sqlday1

Hi tech twitter 👋! I've seen a lot of "X days of coding" challenges. Most of them are about JS, Python or HTML, but a very few about SQL. Here is my turn on that: #learnSQL30days challenge. Every day I'll post one new piece of SQL syntax and explain it. #SQLday1

I started‘Introduction to SQL’ yesterday 🥰🥰🥰 #SQLDay1 #50daysSqlChallenge

#sqlday1 practiced SQL on #hackerrank. Looking forward to daily sql coding while I try to refresh my knowledge.
