> This is not a problem if your DBMS supports SQL recursion

A table of which DMBS’s support this would be useful

[nalgeon]

WITH RECURSIVE is supported in MariaDB 10.2+, MySQL 8.0+, PostgreSQL 8.4+ and SQLite 3.8+. Oracle 11.2+ and SQL Server 2005 support recursive queries, but without the RECURSIVE keyword.

Before recent versions, in the Postgres implementation CTEs were a wall to predicate push-down which can make them much less efficient than in other DBMSs. Worth noting if you need to support older versions for any reason.

[jeltz]

Yeah, but recursive CTEs are a different beast and still do not support pushdown. I am not sure if any database supports pushdown into recursive CTEs.

Not sure if it's up-to date though : https://modern-sql.com/caniuse/with_recursive_(top_level)

FWIW Sybase SQL Anywhere has supported it since v10[1] at least. Current version is v17[2].

This is the list that i could find:

Microsoft SQL Server, Firebird 2.1, PostgreSQL, SQLite, IBM Informix version, CUBRID, MariaDB and MySQL

Not oracle?

[exdsq]

I sort of assumed all of them did!
