What Are The Essential SQL Skills For Senior Business Analysts?

Hello everyone,

I am currently pursuing a career as a Senior Business Analyst, and I know that having a strong understanding of SQL is essential for this role. However, there are so many aspects of SQL to learn, and I’m not sure where to focus my attention.

I would like to know from those who work as Senior Business Analysts, or those who have experience working with them, what are the best aspects of SQL to learn for this position? Which SQL skills do you use the most in your day-to-day work, and which ones have been the most valuable for you?

I appreciate any insights or advice you can offer, and I look forward to learning from your experiences. Thank you!
