[comp.databases] Seeking info on extensions to SQL

gmcgary@eagle_snax.UUCP ( Sun ECD Software) (10/14/87)

I am hacking together an SQL interpreter and would like some leads on
useful extensions.  So far, I've extended the standard language by
fixing some glaring omissions and exceptions to orthogonality (guided
in part by C.J.Date's book on the SQL standard).

If you know of some wizzy non-standard SQL features, please mail me a
description, and I summarize to this news group.

I'm particularly interested in hearing about schema definition
sub-languages that support domains and integrity constraints,
especially referential-integrity.

Thank you!
