Re: [Hibernate] introductions of new keywords to ql

Actually, the HQL parser is capable of using keywords as identifiers in some contexts. I'm not sure what you're saying here, have you modified the grammar and this caused HqlParserTest to fail? If that is the case then there may be something wrong with the modified grammar that is preventing the 'keyword as identifier' from working. If not, then I'm not really sure what the problem is.

Hi Joshua & Steve,

I started working on the EJBQL syntaxes that are not supported yet. I
will need to add some new keywords that might cause some existing tests
to fail. E.g. adding "object" causes the following test to fail

input: ->from org.hibernate.test.Bar bar where bar.object.id = ? and
bar.object.class = ?<-

msg=HQL syntax error : unexpected token: . near line 1, column 42

There was 1 failure:
1)

Am I missing something or there is really no way to fix this except for
disallowing the use of 'object' even in paths?

Thanks.
