EJB3本机查询问题

标签： java ejb-3.0

我有以下内部类：

@Entity
    @Table(name = "SATTET0")
    public class SATTET0Key {
        @Column(name="IESTATUT")
        public String       estatut;
        @Column(name="IINICIO")
        public Date dataInicio;   
    }

在同一课程中，我有以下代码：

Query q = exp.createNativeQuery("SELECT IESTATUT, IINICIO FROM  "
                + "\n SATTET0  WHERE IESTATUT=? AND DATAFIM IS NULL ", SATTET0Key.class);
        q.setParameter(1, estatuto);

        try {
            key = (SATTET0Key) q.getSingleResult();
            return key;
        } catch (NoResultException e) {
            return null;
        }

当我运行此代码时，我得到以下内容：

你在哪里看到“Índicedecolunasinválido”的葡萄牙语翻译“无效的列表索引”

我在这里缺少什么？

3 个答案:

答案 0 :(得分：1)

你应该像这样编写你的原生查询（使用：1而不是？）WHERE IESTATUT =：1 

Query q = exp.createNativeQuery
          (
              "SELECT IESTATUT, IINICIO FROM \n SATTET0  WHERE IESTATUT=:1 AND DATAFIM IS NULL",
              SATTET0Key.class
          );

q.setParameter(1, estatuto);

效果很好。

答案 1 :(得分：0)

参数的索引（1）可能存在问题。可能应该从0开始。

在任何情况下，我都更喜欢在查询中使用命名参数（：param而不是？）。

答案 2 :(得分：0)

我通过完全实现实体并将原始本机查询更改为普通查询来解决了这个问题。这不应该是必需的，但由于某些原因，实施似乎让这件事感到困惑。
