我正在使用这个例子: http ://www.mkyong.com/hibernate/hibernate-query-examples-hql/
并尝试以这种方式删除:
String qhl = "delete from logs where dateTtime >= current_date - interval '1 month'";
Query query = session.createQuery(hql);
return query.executeUpdate();
但我得到这个错误:
ERROR: line 1:61: unexpected token: '1 month'
Mai 23, 2014 3:07:22 PM org.hibernate.hql.internal.ast.ErrorCounter reportError
ERROR: line 1:61: unexpected token: '1 month'

...
尝试此操作时:
String qhl = "delete from logs where dateTtime >= ( select cast(date_trunc('month', current_date) as date) )";
错误是:
logs is not mapped [delete from logs where dateTtime >= ( select cast(date_trunc('month', current_date) as date) )]
我做错了什么?
