【中文标题】jpa命名本机查询无结果【英文标题】：Jpa named native query no result 【发布时间】：2020-02-24 21:16:33 【问题描述】：

我正在尝试将 java spring 云微服务连接到 oracle 数据库。我的问题是，当我调用从函数传递参数的本机查询时，这不会向我返回任何内容，而如果我将其参数直接插入查询中，一切正常。

实体

@Entity
@Table(name = "######")
@SqlResultSetMapping(
        name    = "EmployeeJobDTO",
        classes = @ConstructorResult(
                targetClass = EmployeeJobDTO.class,
                columns     =

【问题讨论】：

【参考方案1】：

您需要使用 spring 的注释 @Param，对于您的情况，代码如下所示：

@Query(name = "findDayJobsByDateAndDepartment", nativeQuery = true)
    public List<EmployeeJobDTO> findDayJobsByDateAndDepartment(@Param("date") String date, @Param("department") String department);

感谢您的回答，我已经尝试使用@Param 注释，但结果没有改变。【参考方案2】：

我通过修改查询解决了，department字段是一个char[8]。

    query   = "select to_char(st.XXXX) as idStf," + 
            "st.XXXX as personalNumber," + 
            "st.XXXX as name," + 
            "st.XXXX as surname," + 
            "sp.XXXX as functionMain," + 
            "dr.XXXX as idDrr," + 
            "dr.XXXX as functionShift," + 
            "dr.XXXX as shiftOldCode," + 
            "dr.XXXX as shiftCode," + 
            "jb.XXXX as idJob," + 
            "jb.XXXX as jobType," + 
            "substr(jb.XXXX, 0, 1) as jobStatus," + 
            "jb.XXXX as plannedFrom," + 
            "jb.XXXX as plannedTo," + 
            "jb.XXXX as actualFrom," + 
            "jb.XXXX as actualTo " + 
            "from XXXXXX jb " + 
            "inner join XXXXXX dr on jb.XXXX = dr.XXXX " + 
            "inner join XXXXXX st on jb.XXXX = st.XXXX " + 
            "inner join XXXXXX sr on sr.XXXX = jb.XXXX " + 
            "inner join XXXXXX sp on sp.XXXX = jb.XXXX " +
            "where dr.XXXX=:date and dr.XXXX = 'A' and trim(sr.XXXX) = :department"

我不明白为什么通过雕刻查询中的字段没有发生错误！
