如何在jpa查詢上傳遞參數？

Question

我有兩個實體，如SmsOut和SmsIn 。 兩個實體之間的關系包含OneToMany ，其中smsIn.id是主鍵 ， smsOut.sms_in_id是外鍵 。

現在我想在查詢上傳遞smsIn.mobileNumber ， smsIn.smsText等參數

SELECT so FROM SmsOut so order by id desc

以下是我的數據庫圖表：

編輯

以下是我的代碼：

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)

請幫我。 謝謝

Answer 1

你沒有解釋SmsIn和SmsOut之間的JPA關系，所以我假設SmsOut有一個與id字段有關系的getSmsIn() 。

當你有一個EntityManager em ，你可以調用em.createQuery ，就像SQL prepare ，然后是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();

有關可以指定參數的不同方法，請參閱Javadoc for Query 。

Answer 2

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

更換 ？ 簽署合適的價值觀。

Answer 3

之間是問題：

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

嘗試

so.smsOutDate between  =:startDate and =:endDate
