Hello all,
Bryan, thanks for the info (although I was using 'locate' on my ubuntu
box, and it still didn't find it ?) I'll have a look tonight.
Kathey, I don't intend to modify the file, just grab the contents, if
possible an without using a file Input Stream
Hi David,
Note that the keywords appear in an array of String constants that are
generated by javacc into
trunk/generated/java/org/apache/derby/impl/sql/compile/SQLParserConstants.java.
That may be a more straightforward way to get your hands on the keywords
but it may require understanding more about how the generated grammar
behaves and it may involve building a compile time tool which scrapes
the keywords out of SQLParserConstants. I am waving my hands, of course.
Hope this helps,
-Rick
I also noted that the DatabaseMetaData.getSQLkeywords() actually has a
hard coded list of words! I have no problem with that in the first
instance, but I'm sure that the engine doesn' check every word with a
call to this method before throwing an error!
I need to keep looking...I'll keep you all posted.

I've had success in pointing Eclipse to the source code that I have

only problem is I can't find it!
It's possible that Eclipse doesn't grok '.jj' files in its normal
configuration.
The file should be in your source tree as:
./java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj
There is a compiler-generation tool that processes this file during
the Ant build of Derby and generates Java source from the grammar.
The tool that generates the java code for the parser from sqlgrammar.jj is
Javacc. The generated code is in
generated/java/org/apache/derby/impl/sql/compile which is fun to look at but
shouldn't be changed.
I think there may be an exclipse plugin for javacc but I have never used
one.
