I most certainly hope this Oracle idiosyncracy will never make it into MySQL.
The SQL standard defines a different syntax for doing recursive queries, using WITH RECURSIVE. I see no reason for MySQL to implement a non-standard way for doing recursive queries when there is a viable alternative (DB2 already uses WITH conform the SQL standard) that has standardized behaviour. I know that a CONNECT BY PRIOR patch is readily available for PostgreSQL but the PostgreSQL developers reject it exactly because it does not follow the SQL standard. I think the PostgreSQL developers are right to do so, non-standard features have caused enough trouble for application portability as it is.

Point taken. I never knew about the WITH RECURSIVE syntax.
Certainly, if CONNECT BY PRIOR is an Oracle only extension, then WITH RECURSIVE does sound like the better option of the two.
