Question

我试图用jpa运行一个应用程序，但我有下一个错误：

Caused by: javax.persistence.PersistenceException: Exception [EclipseLink-8025] (Eclipse    Persistence Services - 2.3.0.v20110604-r9504): org.eclipse.persistence.exceptions.JPQLException

查询所在的文件就是这个：

 @Entity
 @Table(name = "oferta")
 @XmlRootElement
 @NamedQueries({
   ................
 @NamedQuery(name = "Oferta.findByLocalizacion", query = "SELECT o FROM Oferta o WHERE o.negocioCif IN (SELECT cif FROM Negocio WHERE Direccion LIKE :direccion)"),
  .........................})

public class Oferta implements Serializable {

public Integer getIdoferta() {
    return idoferta;
}

    this.idoferta = idoferta;

public Date getFechaInicio() {
    return fechaInicio;

}

    this.negocioCif = negocioCif;
}

@XmlTransient

    return cuponCollection;
}

public void setCuponCollection(Collection<Cupon> cuponCollection) {
    this.cuponCollection = cuponCollection;
}

@Override
public int hashCode() {
    int hash = 0;
    hash += (idoferta != null ? idoferta.hashCode() : 0);
    return hash;
}

@Override
public boolean equals(Object object) {
    // TODO: Warning - this method won't work in the case the id fields are not set
    if (!(object instanceof Oferta)) {
        return false;
    }
    Oferta other = (Oferta) object;
    if ((this.idoferta == null && other.idoferta != null) || (this.idoferta != null && !this.idoferta.equals(other.idoferta))) {
        return false;
    }
    return true;
}

@Override
public String toString() {
    return "com.agrupadosobligatorio.bean.Oferta[ idoferta=" + idoferta + " ]";
}

}

所以你可以看到错误是在subselect上，我不知道如何解决它。拜托，你能帮帮我吗？。

非常感谢

Answer 1

您在subselect中缺少Negocio实体名称，请尝试使用：

SELECT o FROM Oferta o WHERE o.negocioCif IN (SELECT cif FROM Negocio cif WHERE cif.Direccion LIKE :direccion)

或者您可以直接尝试：

SELECT o FROM Oferta o WHERE o.negocioCif.Direccion=:direccion

JPA中的子选择
