To make things more exciting, I integrated <strong>GitHub Copilot</strong> into my workflow.</p> <h3> What I Learned: </h3> <p>Instead of just summarizing data using <code>GROUP BY</code>, Window Functions allowed me to look at data row-by-row while performing advanced calculations using the <code>OVER()</code> clause.</p> <h3> The Copilot Experience: </h3> <p>I used the "Comments to Code" feature, and it was mind-blowing! I wrote a simple comment:<br> <code>-- rank customers by their total sales</code></p> <p>And Copilot instantly generated the query for me. It even gave me great architectural recommendations about using formatting for the <code>MONEY</code> data type and keeping aliases clean.</p> <p>It’s amazing how combining human logic with AI tools can accelerate the learning process. Can't wait to learn more and share my updates here!</p> <h1> dataanalysis #learning #sqlserver #copilot </h1> sql database githubcopilot beginners
