Question

Query eWFqery = em.createQuery("SELECT eworkfirm FROM EsafWorkFirms eworkfirm WHERE eworkfirm.feiNum = :feiNumber AND eworkfirm.getEsafWork().getWorkId() IN :workIdList");
        eWFqery.setParameter("feiNumber", firmObj.getFeiNum());
        eWFqery.setParameter("workIdList", workIdList);

请帮助我遇到以下错误。

错误：

java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager: 
Exception Description: Syntax error parsing [SELECT eworkfirm FROM 
EsafWorkFirms eworkfirm WHERE eworkfirm.feiNum = :feiNumber AND 
eworkfirm.getEsafWork().getWorkId() IN :workIdList]. 
[52, 136] The expression is not a valid conditional expression.

Answer 1

我猜这种语法在jpql中是有问题的：getEsafWork().getWorkId() ...

请尝试尝试（如果列表包含ID）：

eworkfirm.esafWork.workId in ...

...如果列表中包含“作品”，则只需：

eworkfirm.esafWork in ...

收到错误：该表达式不是有效的条件表达式
