Hibernate Query，如何使用like或= on where子句依赖于传递的值

Question

我有以下代码和查询：

String kodeCustomer, kodeDropship, kodeSales, kodePengirim;

kodeCustomer = kodeCustomerTextField.getText().trim();
kodeDropship = kodeDropshipTextField.getText().trim();
kodeSales    = kodeSalesTextField.getText().trim();
kodePengirim = pengirimTextField.getText().trim();

... some other code ... 
      record = session.createQuery("from PenjualanTableDb where"
    + " dtanggalpenjualan >= :dawalParm"
        + " and dtanggalpenjualan < :dakhirParm"
        + " and coalesce(ckodecustomer,'') like :custParm"
        + " and coalesce(ckodedropship,'') like :dropshipParm"
        + " and coalesce(ckodesalesperson,'') like :salesParm"
        + " and coalesce(ckodepengirim,'') like :pengirimParm")
    .setParameter("dawalParm", tanggalMulaiTrx)
        .setParameter("dakhirParm", tanggalAkhirTrx)
        .setParameter("custParm", kodeCustomer + "%")
        .setParameter("dropshipParm", kodeDropship + "%")
        .setParameter("salesParm", kodeSales + "%")
        .setParameter("pengirimParm", kodePengirim + "%")
    .list();

如何修改查询，以便它可以根据用户输入提供正确的输出。如果textfield为空，则查询使用like，但如果textfield不为空，则查询使用=

有没有一种简单的方法来处理它？

提前致谢

Answer 1

我认为你应该根据存在的参数动态构造hql查询（包括参数），而不是使用“类似％”。

Answer 2

record = session.createQuery("from PenjualanTableDb where"
    + " dtanggalpenjualan >= :dawalParm"
        + " and dtanggalpenjualan < :dakhirParm"
        + " and coalesce(ckodecustomer,'') like '%:custParm%'"
        + " and coalesce(ckodedropship,'') like '%:dropshipParm%'"
        + " and coalesce(ckodesalesperson,'') like '%:salesParm%'"
        + " and coalesce(ckodepengirim,'') like '%:pengirimParm%'")
    .setParameter("dawalParm", tanggalMulaiTrx)
        .setParameter("dakhirParm", tanggalAkhirTrx)
        .setParameter("custParm", kodeCustomer)
        .setParameter("dropshipParm", kodeDropship)
        .setParameter("salesParm", kodeSales)
        .setParameter("pengirimParm", kodePengirim)
    .list();
