如何在jpa查询上传递参数？

Question

我有两个实体，如 SmsOut 和 SmsIn 。两个实体之间的关系包含 OneToMany ，其中 smsIn.id 是主键， smsOut.sms_in_id 是外键。

现在我想在查询

上传递 smsIn.mobileNumber ， smsIn.smsText 之类的参数等等

SELECT so FROM SmsOut so order by id desc

以下是我的数据库图表：

被修改

以下是我的代码：

String sql = "SELECT so FROM SmsOut so WHERE so.smsInId.mobileNumber =:mobileNumber AND so.smsInId.smsText =:smsText AND so.smsInId.shortCode =:shortCode between so.smsOutDate =:startDate and so.smsOutDate =:endDate order by id desc";
    Query query = em.createQuery(sql);
    query.setParameter("mobileNumber", mobileNumber);
    query.setParameter("smsText", smsText);
    query.setParameter("shortCode", shortCode);
    query.setParameter("smsOutDate", startDate);
    query.setParameter("smsOutDate", endDate);
    smsOutList = query.getResultList();

，例外是：

SEVERE: line 1:188: expecting "and", found '='
java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: expecting "and", found '=' near line 1, column 188 [SELECT so FROM     com.f1soft.SMSC.entities.SmsOut so WHERE so.smsInId.mobileNumber =:mobileNumber AND so.smsInId.smsText =:smsText AND so.smsInId.shortCode =:shortCode between so.smsOutDate =:startDate and so.smsOutDate =:endDate order by id desc]
at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:624)
at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:96)

请帮帮我。 谢谢

Answer 1

您尚未解释SmsIn与SmsOut之间的JPA关系，因此我假设SmsOut的{​​{1}}与getSmsIn()有关系id } field。

如果您有EntityManager em，则可以拨打em.createQuery，类似于SQL prepare，然后setParameter：

TypedQuery<SmsOut> q = em.createQuery("SELECT so FROM SmsOut so WHERE so.smsIn.mobileNumber = :number ORDER BY id DESC");
q.setParameter("number", "12345678");
List<SmsOut> results = q.getResultList();

有关指定参数的不同方法，请参阅the Javadoc for Query。

Answer 2

SELECT so FROM SmsOut so WHERE smsIn.mobileNumber = ? AND smsIn.smsText =? order by id desc

更换？签署适当的值。

Answer 3

之间是问题所在：

between so.smsOutDate =:startDate and so.smsOutDate =:endDate 

尝试

so.smsOutDate between  =:startDate and =:endDate
