Re: [hibernate-dev] Empty IN list support
I see that we are only using it for testing so that we can skip the:
testEmptyInListQuery
query on certain Dialects.
We could use this info when rendering the JPQL/HQL queries to throw an
exception before executing the query.
Nevertheless, an exception will be thrown anyway even if we don't do it.

Hi,
HANA doesn't support empty IN lists, so executing an HQL query that gets
transformed into a SQL query with an empty IN list results in a SQL parser
error on the database side. I noticed that the Dialect class already
defines a method called "supportsEmptyInList()" which according to the
Javadoc returns "True if empty in lists are supported; false otherwise".
However, this method doesn't seem to be used anywhere in the Hibernate
code. Is there a reason for that?
Thanks,
Jonathan
