With me, Grgrjobs, you’ll learn SQL step by step in a way that feels simple and practical. We’ll start with the basics, such as understanding databases, tables, and how to create and manage them. You’ll practice writing queries to insert, update, delete, and retrieve data confidently.
Once you’re comfortable, we’ll move on to more powerful SQL tools. You’ll learn how to filter and sort data, use functions like COUNT, SUM, and AVG, and work with dates and strings. We’ll then explore how to combine data from different tables using joins, and I’ll show you how relationships between tables really work in real-world scenarios.
As you progress, I’ll introduce advanced concepts like subqueries, grouping data, conditional logic with CASE, and window functions that are widely used in data analysis. We’ll also discuss transactions, indexes, and techniques to improve query performance, so you know not just how to write SQL, but how to write it well.
Finally, I’ll guide you through real-world applications. Together, we’ll solve practical problems using datasets like sales records, student data, or e-commerce examples. By the end, you’ll have both the confidence and the skills to apply SQL in data science, analytics, or business projects.
