我有问题惠特Hibernate查询，我在te DDBB hibernate启动时执行删除一行的过程跟随错误：

该实体是：

@Entity
@Table(name = "loan_person_rel")
public class LoanPersonRelation extends GCEntity {

private String personId;
private String loanId;
private int type;

public String getPersonId() {
    return personId;
}

public void setPersonId(String personId) {
    this.personId = personId;
}

public String getLoanId() {
    return loanId;
}

public void setLoanId(String loanId) {
    this.loanId = loanId;
}

public int getType() {
    return type;
}

public void setType(int type) {
    this.type = type;
}
}

存储库中的方法是：

@Override
public int getPersonType(String personId, String loanId) {
    Query personTypeQuery = getSessionFactory().createSQLQuery(
            "SELECT lpr.type FROM LoanPersonRelation lpr WHERE lpr.personId = :person_id AND lpr.loanId = :loan_id");
    personTypeQuery.setParameter("person_id", personId);
    personTypeQuery.setParameter("loan_id", loanId);
    return (int) personTypeQuery.uniqueResult();
}

生成的查询是：

Hibernate: 
SELECT
    lpr.type 
FROM
    LoanPersonRelation lpr 
WHERE
    lpr.personId = ? 
    AND lpr.loanId = ?

我怎么能解决这个问题？

感谢。

您在这里使用本机SQL，因此应使用实际的DB表名（loan_person_rel）。

Hibernate DELETE查询错误由以下引起：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：Table＆＃39; gestcart.loanpersonrelation＆＃39;不存在
