Can MySQL Use the WITH Clause for Common Table Expressions (CTEs)?

MySQL does not support the WITH clause to create a common table expression (CTE)

Overview

Common Table Expression (CTE) is a powerful tool in SQL programming that allows the creation of reusable subqueries and recursive queries. However, the "WITH" clause for CTE is notably missing from MySQL.

Question

Is it possible to force MySQL to use the "WITH" clause?

Answer

Before MySQL 8.0, the answer was absolutely no. MySQL 5.x and earlier versions do not support this feature.

Common table expressions in MySQL 8.0

After the release of MySQL version 8.0, CTE was finally introduced as part of the "Labs" feature set. This allows developers to write queries using "WITH" clauses, taking advantage of the power of recursive CTEs and simplifying complex data retrieval tasks.

Instructions for MySQL versions before 8.0

For MySQL versions prior to 8.0, CTE cannot be used. Alternative methods, such as subqueries or stored procedures, may be needed to achieve similar functionality.
