Does MySQL Support Common Table Expressions (CTEs) Using the 'WITH' Clause?

MySQL 8.0 and the Power of CTEs

MySQL, a popular relational database management system, didn't initially support Common Table Expressions (CTEs) using the WITH clause. This clause provides a powerful mechanism for creating and managing temporary result sets within SQL queries.

The Arrival of the WITH Clause

While earlier MySQL 5.x versions lacked this functionality, MySQL 8.0 introduced full support for both standard and recursive CTEs, dramatically increasing the database's query capabilities.

Workarounds in Older Versions

Before MySQL 8.0, developers relied on subqueries to mimic CTE behavior. This method, however, proved less efficient and more complex than the elegant WITH clause.

Industry Standard Alignment

The WITH clause is a standard SQL feature found in many other database systems, such as Oracle, Microsoft SQL Server, DB2, and PostgreSQL. Its inclusion in MySQL 8.0 brings MySQL into better alignment with industry best practices and improves compatibility across different database platforms.
