java.sql.SQLSyntaxErrorException: ORA-00936: 缺失表达式

热度:1269   发布时间:2016-04-17 01:07:00.0
帮忙看下这段hsql语句吧
Java code
session.createQuery("count(e.emails) from Employee e where e.email = :eml").setString("eml", e.getEmail()).uniqueResult();


说明一下,Employee这个类中有一个集合类型是Email类型的,他们是多对多的关系,现在我想要拿出Employee中得emails的总数,我这么些hsql语句后报错了如下错误:
