Yep, I just spotted another location where you can download most of the 1999 version of the SQL Standard.
It's right here: http://www.cse.iitb.ac.in/dbms/Data/Papers-Other/SQL1999/.
As far as I can see, here the 3rd part is missing too, like in the location I blogged about before.
Not that I would encourage anyone to illegally download it, of course. I mean, altough it's a standard, I really think you should pay money to ISO and IEC, even though it´s a teeny weeny outdated.
