The Quick Byte
One coding tip because you’re technical after all

This week’s coding challenge:

This week’s tip:

Common Table Expressions (CTEs) in SQL allow you to define temporary result sets that can be referenced within a SELECT, INSERT, UPDATE, or DELETE statement. They make complex queries more readable and maintainable.


  • Complex Queries: Ideal for breaking down complex queries into more manageable parts.

  • Recursive Queries: Useful for performing recursive operations like hierarchy traversals.

  • Improving Readability: Efficient for improving the readability and organization of SQL statements.


  • Readability: Enhances readability by separating query logic into distinct, named components.

  • Maintainability: Simplifies query maintenance and updates by breaking down logic into manageable parts.

  • Modularity: Encourages a modular approach to query design, making it easier to test and debug.
