SQL92 specification ....

Hi guys ....

I need, want,(whatever...nevermind) the SQL92 ISO/ANSI documents(it seems
they are 4 or something like that).

I´ve been looking around the web, and everywhere you find the document, you
have to pay for it. 

If people are making the software free, why not the important documents,
like these kind of standards???

Since you´re the Postgresql developers, which seems to be very
SQL92-compliant, I suppose you have the documents??? Don´t you???, so, could
you send me a copy of them??? Or tell me where can a find them??? Or tell me
that I´ve to buy it??? I don´t know....

Thanks in advance ... seya

Ps. By the way, what about SQL3 standard-documents????? Are they done and
available?????

Because selling the standards documents is a traditional way for
standards bodies to (help) pay their expenses.

If you want to buy two copies, send us one ;)

In the meantime, we use a combination of SQL92 *draft* standard
documents and reliable texts such as Date and Darwen to try to
understand the standard. And it works pretty well, especially since
most other databases don't match the standard exactly anyway, so we do
OK by comparison just by trying to meet it.

afaik *only* available as a draft standard, and afaik *nothing*
available fresher than at least a couple of years old.

I've just deposited two gzip'd files at
 ftp://postgresql.org/pub/doc/sql/

which are the only "standards" docs I know about.

Good luck (especially on the SQL3 one).

As I know this is still the actual draft.
