Knut Anders Hatlen commented on DERBY-6609:
-------------------------------------------

Thanks, Kim. The #6 patch looks good. +1 to commit.

In my description of the support for F382, I failed to mention that VARCHAR FOR 
BIT DATA was supported, so we might want to add that.

I noticed that the #5 patch sometimes said "Part 2 (Core SQL)". Core SQL is 
actually the set of mandatory features in part 2 and 11 plus some optional 
features. The name of Part 2 is Foundation, so I think it would be more correct 
to say "Part 2 (Foundation)".

I've filed DERBY-6644 to implement the standard syntax for set/drop not null. 
It looks like an easy fix, so hopefully we can remove that comment soon.

> We document Derby as an SQL-92 database. This standard is now very old, and 
> we should describe how Derby conforms to the most current standard 
> (SQL:2011). Knut Anders Hatlen listed the relevant features in a comment to 
> DERBY-6605. 
> This will involve at a minimum replacing the "Derby support for SQL-92 
> features" topic 
> (http://db.apache.org/derby/docs/10.10/ref/rrefsql9241891.html) with a new 
> one that describes Derby's support for current features, with notes as needed 
> indicating when the support is partial. Only features Derby supports, fully 
> or partially, should be listed. We should state that features not listed are 
> not supported.
> The information would be taken from 
> http://wiki.apache.org/db-derby/SQLvsDerbyFeatures (which currently goes only 
> through the 2003 standard). Listing the Feature IDs in the documentation 
> would also be helpful. 
> Other topics should be changed as needed. For example, is the term 
> "SQL92Identifier" still correct?
