> According to the comments in sqlgrammar.jj, Derby's understanding of reserved vs. non-reserved
keywords is supposed to be based on SQL 92. However, Derby has 8 reserved keywords which are
not part of the SQL 92 list of reserved keywords. The SQL 2003 spec moved many of the SQL
92 reserved keywords to the non-reserved list. Derby has 55 reserved keywords which are not
part of the SQL 2003 list. 42 of Derby's reserved keywords are in the SQL 2003 list of non-reserved
keywords.
> The reserved keywords create migration problems when moving applications from other databases
to Derby. We should consider whether there is any reason that Derby should have more reserved
keywords than appear in the SQL 2003 standard.
