Why this hibernate template bulkUpdate doesn't work

Oracle 10g, Hibernate 3.4

This update (based on long user.userId value) is done correctly:

getHibernateTemplate().bulkUpdate("update Address address set address.preferred = 1 where address.user.userId = ?", 1l);

This one (based on String user.language value) throws an exception ORA-00971: missing SET key开发者_开发百科word:

getHibernateTemplate().bulkUpdate("update Address address set address.preferred = 1 where address.user.language = ?", "en");

Anybody knows why?

Hibernate documentation says:

• No joins, either implicit or explicit, can be specified in a bulk HQL query. Sub-queries can be used in the where-clause, where the subqueries themselves may contain joins.

So, you need to replace implicit join with the equivalent subquery:

getHibernateTemplate().bulkUpdate(
   "update Address address set address.preferred = 1 " +
   "where address.user in (select u from User u where u.language = ?)",
   "en");
