Just a follow up to me earlier post on reading the SQL 2006 Draft Standards (here), Glenn Pauley of Sybase pointed out to me that you download the standards for much less from the ANSI Store at http://webstore.ansi.org. The ANSI/ISO SQL Standards are all code with "9075" so the easiest way is to use the Document Number search for "IEC 9075".

And the good news is that the SQL:2003 standards are just $30 for each section.  The bad news is that there are 14 sections and the SQL:2008 documents are $180 apeice.
