Query with empty restriction
vk101 Mar 19, 2007 2:03 AMI get the following exception when I have in components.xml the following query, but #{member.countries} refers to an empty list:
SELECT c FROM Country c where c IN (#{member.countries})
If you look at the root cause of the error the message says:
org.hibernate.hql.ast.QuerySyntaxException: unexpected end of subtree [SELECT c FROM Country c where c IN ()]
The #{member.countries} expression for a member that has no countries specified doesn't show up in the generated query ("SELECT c FROM Country c where c IN ()"). Why is this happening, and how could I cause the query to simply return an empty list instead of this exception?
Thanks.
