Обсуждение: FYI: BNF for SQL93 and SQL-3

Doing a Google search for SQL standards, I found a 
wonderful page of links to SQL info, including the BNF 
specs for SQL92 and SQL3. Not exactly gram.y but hopefully 
close. 

Could be helpful in deciphering what the standards say.

How official is this? I get the feeling this might
be one guy's interpretation because it seems like
it is missing stuff.

I guess it is lifted from the standard as it was in september 1993.

OTOH, the SQL3 standard is still not final.

Is it progressing, or is it in disrepair?
