Why Learn SQL When AI Can Generate Code?

  • Review and Trust: You need to read and understand the queries AI generates to ensure they are correct and safe for your data.
  • Customization: Business questions are often unique. Knowing SQL lets you quickly adjust or combine queries to fit your exact needs.
  • Communication: Understanding SQL helps you communicate requirements clearly with IT or data teams, and spot mistakes or inefficiencies.
  • Problem Solving: Sometimes, AI suggestions may not work as expected. Knowing SQL basics lets you troubleshoot and fix issues on your own.
  • Confidence: With SQL skills, you can use AI as a helpful assistant—not a crutch—making you faster and more effective.
