Home -> Community -> Mailing Lists -> Oracle-L -> RE: Anyone with experience with MMOG and databases?
with all due respect, it looks to me that you are debating just for the sport of
disagreeing.
that's a nice sport, by the way, and it keeps you sharp -- but this is just too
easy...
there are *no* ISO SQL compliant DBMSses at all. period. and maybe that's a good thing -- the standard has it's own problems, and backward compatibility issues caused by horrible mistakes made in earlier versions of the standard.
you mention SQL/PSM as an example of standards non-compliance, and when I say that it is not part of the standard, you say that it is important. duh. to whom? even many ISO standardization committee members (I know quite a few of them) more or less agree that SQL/PSM is not important as a standard.
portability does *not* matter -- portability is a wet dream. if you think that an application written in fully ANSI/ISO standard SQL is portable from SQL Server to Oracle, or the other way around, you are sorely mistaken -- because the applications will behave differently. Just think about the rather unique and sophisticated non-locking read consistency model implemented by Oracle. Just search Tom Kyte's website for some nice threads on this topic.
proprietary extensions being crap? give me a break, and don't generalize ...
please, let's forget about D -- until it is implemented. it is a promising theoretical framework, and as such highly interesting -- but it will need another revolution, just like Ted Codd started one around 1970, to make it mainstream.
kind regards,
Lex.

I do think every SQL DBMS should be ISO compliant. I do think ISO SQL isn't any good.
The thing is that there is a value in a standard by itself -- portability matters.
On the other hand, most proprietary extensions are just crap. So standards help getting some minimum quality.
Finally, the thing I'd like to see instead of ISO SQL is not SQL at all, but The Third Manifesto's D.
