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
