Day 13/30 It’s Day 13 of my SQL learning challenge, and I’ve decided to take a step back to recap and solidify everything I’ve learned so far. This journey has been both rewarding and eye-opening, pushing me to think critically and approach data from new angles. Consistency has been the key while every day brings new insights and builds on the previous day’s knowledge. While it hasn’t been without its challenges, the progress is worth every bit of effort. I’m excited for the next steps and eager to explore more advanced concepts as I continue this journey. Here’s to growth and the pursuit of mastering SQL.

SQL has been my go-to tool for turning raw data into meaningful insights. Over the years, I've spent countless hours working with databases, learning how to craft the perfect query, and optimize data retrieval. It wasn’t always easy—there were times when I got stuck on a complex query or misunderstood a JOIN function. But those moments of struggle were also the moments of growth. I remember when I first started with SQL; it felt like learning a new language. I made mistakes—lots of them. There was one time I accidentally ran a query that updated an entire table instead of just a few rows. It was a humbling experience, to say the least. But each mistake taught me something new and pushed me to get better. Today, I’m sharing a SQL cheatsheet that I wish I had when I first started. It’s a simple guide, but it’s packed with the essentials that every data analyst needs to know. Whether you’re just getting started or looking to refine your skills, I hope you find it as useful as I do.
