休眠：引起：java.sql.SQLException：操作数应包含 1 列答案

例外：引起：java.sql.SQLException：操作数应包含 1 列原因：org.hibernate.exception.DataException：无法提取ResultSet

我写的HQL如下：

select sm from SystemMessage sm 
left join sm.systemMessageMaps smrm 
left join smrm.role r
left join smrm.projectGroup pg
left join smrm.assessmentVersion av 
left join smrm.severity sms
where ( (r.id is NULL) and (pg.id is NULL) and (av.id IN (:assesmentVersionID) ) 
         or(pg.code =:projectGroup and av.id IN (:assesmentVersionID) and  r.id is NULL) 
         or(r.name =:roleName AND av.id IN (:assesmentVersionID) and pg.id is NULL)
         or( r.name =:roleName and  pg.code =:projectGroup AND av.id IN (:assesmentVersionID) ) 
       ) and 
      ( ( sm.startDate is null or sm.startDate <= current_timestamp ) and ( sm.endDate is null or sm.endDate >= current_timestamp)) 
order by sms.priority,smrm.severityRank,sm.startDate

在将 in 子句添加到参数后，我碰巧得到了这个异常：

av.id IN (:assesmentVersionID)

我将参数值设置为

query.setParameterList("assesmentVersionID", assessmentVersionIDList);

我想知道我哪里出错了！

【问题讨论】：

我使用的是Hibernate，BatchPreparedStatementSetter是JdbcTemplate类使用的批量更新回调接口。听起来不相关吗？
是的，很抱歉，删除了评论

【解决方案1】：

尝试删除括号：

select sm from SystemMessage sm 
left join sm.systemMessageMaps smrm 
left join smrm.role r
left join smrm.projectGroup pg
left join smrm.assessmentVersion av 
left join smrm.severity sms
where ( (r.id is NULL) and (pg.id is NULL) and av.id IN (:assesmentVersionID) 
         or(pg.code =:projectGroup and av.id IN (:assesmentVersionID) and  r.id is NULL) 
         or(r.name =:roleName AND av.id IN (:assesmentVersionID) and pg.id is NULL)
         or( r.name =:roleName and  pg.code =:projectGroup AND av.id IN (:assesmentVersionID) ) 
       ) and 
      ( ( sm.startDate is null or sm.startDate <= current_timestamp ) and ( sm.endDate is null or sm.endDate >= current_timestamp)) 
order by sms.priority,smrm.severityRank,sm.startDate

这应该可以，如果不尝试从(:assesmentVersionID) 中删除括号。

如果它解决了问题，请告诉我。
