Neil,
Compatibility is the ONLY reason and it is related to money (the only
language people understand).
We have done a lot of migration here and I can tell you that support for
Oracle style CONNECT BY would make more people happy than the SQL style
syntax.
The reason for that is very simple: Code can be migrated without any
changes (= without introducing potential bugs).
I know that SQL standards are tremendously important but if there is an
easy way to support Oracle syntax as well this is definitely the
preferred way to go.
I think it is important not to think in dogmas (in this case this means
SQL syntax is always better) - there should be a reasonable compromise
between compatibility and standard.
My compromise would be: Support both syntaxes if possible.
Best regards,
Hans
