我使用以下查询:
SELECT * FROM phaseinproject as pip JOIN projectinrelease pir
ON pip.projectInRelease_id = pir.id
JOIN releaseperiod as rp ON pir.release_id = rp.id
JOIN releasestructure as rs ON rs.id = rp.releaseStructure_id
JOIN phaseinreleasestructure as pirs ON pirs.releaseStructure_id = rs.id
JOIN releasephase as rlp ON rlp.id = pirs.phase_id
AND rlp.id = pip.phase_id
此查询完全正常。我得到三个结果(我期望的数量)。
我将此查询转换为以下HQL查询:
TypedQuery<PhaseInProjectOverview> findPhasesInRelease = em.createQuery("SELECT NEW nl.dashboard.dto.out.PhaseInProjectOverview(phaseInProject.id, phase.name, phaseInProject.startDate, phaseInProject.plannedEndDate, phaseInProject.endDate) FROM PhaseInProject phaseInProject "
+ "JOIN phaseInProject.projectInRelease projectInRelease "
+ "JOIN projectInRelease.release release "
+ "JOIN release.releaseStructure releaseStructure "
+ "JOIN releaseStructure.phaseInReleaseStructures phaseInReleaseStructure "
+ "JOIN phaseInReleaseStructure.phase phase "
+ "WHERE release.id = :releaseId ORDER BY phaseInReleaseStructure.position, phaseInProject.startDate", PhaseInProjectOverview.class);
findPhasesInRelease.setParameter("releaseId", releaseId);
return findPhasesInRelease.getResultList();
无论我尝试什么:我都会得到6个结果,因为HQL似乎不支持
"JOIN ... ON ... AND ..."
sql语法。有谁知道如何解决这个问题?
编辑:
我在使用的解决方案中添加了自己的答案。谢谢大家的答案/指标。
最佳答案
尝试with关键字:phaseInReleaseStructure.phase phase WITH phase.id = phaseInProject.phase_id
-这应该导致像releasephase as rlp ON rlp.id = pirs.phase_id AND rlp.id = pip.phase_id
这样的SQL
或者,只需在where子句中添加该条件:
... WHERE release.id = :releaseId AND phase.id = phaseInProject.phase_id ...
