给出这个查询:
"SELECT DISTINCT lc.id, lc.debtor.officialCompanyName, lc.liquidationPublicationDate, lc.regNumberLegalRepresentative, lc.regNumberLiquidatorCompany, lc.liquidationStatusType, "
+ "lc.authority, lc.liquidationSupervisor, lc.liquidationFinalizationDate, lc.finalReportFilingDate "
+ "FROM LiquidationCase lc "
+ "WHERE lc.active = 1 AND (lc.clerk = :user "
+ "OR :user MEMBER OF lc.endemicSite.company.managers "
+ "OR :user MEMBER OF lc.endemicSite.managers) "
+ "AND lc.endemicSite.id = :endemicSiteId ")"
如果我添加 lc.clerk 到selected attributes，像这样:
"SELECT DISTINCT lc.id, lc.debtor.officialCompanyName, lc.liquidationPublicationDate, lc.regNumberLegalRepresentative, lc.regNumberLiquidatorCompany, lc.liquidationStatusType, "
+ "lc.authority, lc.clerk, lc.liquidationSupervisor, lc.liquidationFinalizationDate, lc.finalReportFilingDate "
+ "FROM LiquidationCase lc "
+ "WHERE lc.active = 1 AND (lc.clerk = :user "
+ "OR :user MEMBER OF lc.endemicSite.company.managers "
+ "OR :user MEMBER OF lc.endemicSite.managers) "
+ "AND lc.endemicSite.id = :endemicSiteId "
那么 lc-s 的 clerk 值为 null 将不会被选中，但是我想获得这些 lc-s (liquidCases)。不知何故，生成的查询并不好。
知道如何解决这个问题吗(请不要提及从数据库中选择的后处理职员)？
非常感谢任何提示。

最佳答案
Clerk 是一个关系映射，因此如果您希望查询包含 null，则需要告诉它对关系使用外连接:
Select clerk, ... From LiquidationCase lc left join lc.clerk clerk...
关于java - 发现另一个 JPA 奇怪的案例(添加一个 selected 属性完全改变了查询的结果集)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27024644/
