我有以下 MySQL 本机查询。
SELECT w.weight_id, w.weight, zc.charge
FROM weight w
LEFT OUTER JOIN zone_charge zc ON w.weight_id=zc.weight_id
AND zc.zone_id=? --<--------
ORDER BY w.weight ASC
我需要通过带有 EclipseLink 2.0 的 JPA 执行此语句。我尝试通过以下方式转换此查询。
SELECT w.weightId, w.weight, zc.charge
FROM Weight w
LEFT JOIN FETCH w.zoneChargeSet zc
WITH zc.zoneTable.zoneId=:id --<--------
ORDER BY w.weight
entityManager.createQuery("The above query")
.setParameter("id", id)
.getResultList();
但不幸的是,它会导致引发以下异常。
java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager:
Exception Description: Syntax error parsing [select w.weightId, w.weight, zc.charge from Weight w left join fetch w.zoneChargeSet zc with zc.zoneTable.zoneId=:id order by w.weight].
[87, 88] The FROM clause has 'Weight w LEFT JOIN FETCH w.zoneChargeSet zc' and 'with zc.zoneTable.zoneId' that are not separated by a comma.
[93, 112] The identification variable 'zc.zoneTable.zoneId' is not following the rules for a Java identifier.
[112, 134] The query contains a malformed ending.
这适用于 Hibernate 作为 JPA 提供程序。
如何通过 EclipseLink 运行此查询?我特别在寻找条件查询,但是WITH
Hibernate 提供程序似乎也不支持这个(运算符)。
这是完整的异常堆栈跟踪。

编辑 :
根据下面的答案,我有这个 JPQL:
SELECT
w.weightId,
w.weight,
zc.charge
FROM
Weight w
LEFT JOIN FETCH
w.zoneChargeSet zc
ON
zc.zoneTable.zoneId=:id
ORDER BY
w.weight ASC
这会生成以下正确的 SQL:
SELECT
t0.weight_id,
t0.weight,
t1.charge
FROM
projectdb.weight t0
LEFT OUTER JOIN
projectdb.zone_charge t1
ON
((t1.weight_id = t0.weight_id)
AND
(t1.zone_id = ?))
ORDER BY
t0.weight
ASC
是否可以将此 JPQL 转换为条件查询。我最终得到了以下条件查询。
CriteriaBuilder criteriaBuilder=entityManager.getCriteriaBuilder();
CriteriaQuery<Tuple>criteriaQuery=criteriaBuilder.createTupleQuery();
Root<Weight> root = criteriaQuery.from(entityManager.getMetamodel().entity(Weight.class));
SetJoin<Weight, ZoneCharge> join = root.join(Weight_.zoneChargeSet, JoinType.LEFT);
ParameterExpression<Long>parameterExpression=criteriaBuilder.parameter(Long.class);
criteriaQuery.where(criteriaBuilder.equal(join.get(ZoneCharge_.zoneTable).get(ZoneTable_.zoneId), parameterExpression));
criteriaQuery.multiselect(root.get(Weight_.weightId), root.get(Weight_.weight), join.get(ZoneCharge_.charge));
criteriaQuery.orderBy(criteriaBuilder.asc(root.get(Weight_.weight)));
TypedQuery<Tuple> typedQuery = entityManager.createQuery(criteriaQuery).setParameter(parameterExpression, id);
typedQuery.getResultList();
它产生以下 SQL:
SELECT
t0.weight_id,
t0.weight,
t1.charge
FROM
projectdb.weight t0
LEFT OUTER JOIN
projectdb.zone_charge t1
ON
(t1.weight_id = t0.weight_id)
WHERE
(t1.zone_id = ?)
ORDER BY
t0.weight
ASC
WHERE
可以改成AND
吗?
这个答案所说的不可用(on()
似乎不存在org.eclipse.persistence.internal.jpa.querydef.JoinImpl
)。这样做是编译时错误!
