This is a general question about H3's query parsers.

As it, there's to query parsers, the new org.hibernate.hql.ast.ASTQueryTranslatorFactory and the classic org.hibernate.hql.classic.ClassicQueryTranslatorFactory (from 2.1.6).

The ClassicQueryTranslatorFactory support non-ANSI join clause (*= & =*) but ASTQueryTranslatorFactory does not.

Is there a plan to support non-ANSI join in ASTQueryTranslatorFactory?

If so, do you know when (estimate or version #) it will?

Thanks

No it will not support this. Theta-style joins have never been a supported syntax in HQL. Its simply that the old parser was much more lax about certain stuff, passing a lot of stuff through to the database that it did not understand.
