I have updated the developer's FAQ with this information: --------------------------------------------------------------------------- 1.12) Where can I get a copy of the SQL standards? There are two pertinent standards, SQL92 and SQL99. These standards are endorsed by ANSI and ISO. A draft of the SQL92 standard is available at http://www.contrib.andrew.cmu.edu/~shadow/. The SQL99 standard must be purchased from ANSI at http://webstore.ansi.org/ansidocstore/default.asp. The main standards documents are ANSI X3.135-1992 for SQL92 and ANSI/ISO/IEC 9075-2-1999 for SQL99. A summary of these standards is at http://dbs.uni-leipzig.de/en/lokal/standards.pdf and http://db.konkuk.ac.kr/present/SQL3.pdf. --------------------------------------------------------------------------- Tom Lane wrote: > "Rod Taylor" <rbt@zort.ca> writes: > > I've not found a cheap resource for the real one.
