I get HibernateException : ordinal parameter mismatch when I try to execute the following query :
Code:
select b.url, count(b.url) from Bookmark b  group by b.url order by count(b.url) desc, b.timestamp desc where  b.timestamp between ? and ?
However, the following version (without where clause) works fine :
Code:
select b.url, count(b.url) from Bookmark b  group by b.url order by count(b.url) desc, b.timestamp desc 
I used the HibernateTools for Eclipse and tested it by passing parameters of type 'timestamp' with the proper format.
What is wrong in my HQL ? 
I am attaching the mapping files and other information below.

Name and version of the database you are using: MySQL 5.1I saw a JIRA Issue raised at 
http://opensource.atlassian.com/projects/hibernate/browse/HHH-1423. Does this has any relationship to my problem?
Thanks.
