查询

String sSubQuery =  "SELECT om.path, om.originalSize, MAX(om.lastModified) "+
                    "FROM "+
                    "ObjectMetadata om "+
                    "WHERE om.informationStoreId = '"+informationStoreDefinitionID+"' "+
                    "GROUP BY om.path, om.originalSize";

             String sQuery =  "SELECT SUM(o.originalSize) "+
                    "FROM "+
                    "("+
                    " "+sSubQuery+
                    " ) "+
                    "o";

            Query q = getEm().createQuery(sQuery);

请帮助。

尝试

String sSubQuery = "SELECT SUM(om.originalSize), MAX(om.lastModified) "+ 
                   "FROM "+ "ObjectMetadata om "+ 
                   "WHERE om.informationStoreId = :informationStoreDefinitionID "+ 
                   "GROUP BY om.path, om.originalSize";

Query q = getEm().createQuery(sQuery);
q.addParameter("informationStoreDefinitionID",22);

org.hibernate.hql.internal.ast.ErrorCounter：意外令牌:(
