我有一个查询，我想使用hibernate native sqlQuery

运行它

当我使用sql developer运行查询时它工作正常但是当hibernate运行它时会抛出此异常

java.sql.SQLException: Invalid column name

这是来自hibernate日志的查询：

Hibernate: select o.GUICHET,count(*) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) and c.centre_id=? and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET group by o.GUICHET

这是我的表类定义：

@Entity
@Table(name = "operations")
public class Operations implements Serializable  {

    private static final long serialVersionUID = 1L;

    @GeneratedValue(strategy= GenerationType.AUTO)
    @Id
    private Long operationsId;
    private Date dateOperations;
    @ManyToOne()
    @JoinColumn(name = "guichet", referencedColumnName = "guichetId")
    private Guichet guichet;

编辑：这是我定义此方法并使用它的代码

@Repository
public interface OperationsRepository extends CrudRepository<Operations, Long> {

    @Query(value="select o.guichet,count(*) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) " + 
            "and c.centre_id=?1 and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET " + 
            "group by o.guichet",nativeQuery=true)
    Iterable<Operations> operationsStat( Long centreId);

使用此方法：

@Override
    public Iterable<Operations> operationsStat(Long centreId) {
        return operationsRepository.operationsStat(centreId);
    }


@GetMapping(value="/statistique")
    @ResponseBody()
    Iterable<Operations> doStatistique()
    {
        return operationsServiceImpl.operationsStat(new Long(selectedCentre)); 
    }

更改返回类型后的代码：

@Repository
public interface OperationsRepository extends CrudRepository<Operations, Long> {

    @Query(value="select o.guichet,count(*) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) " + 
            "and c.centre_id=?1 and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET " + 
            "group by o.guichet",nativeQuery=true)
    Iterable<Object> operationsStat( Long centreId);

然后这个：

@Override
    public Iterable<Object> operationsStat(Long centreId) {
        return operationsRepository.operationsStat(centreId);
    }


@GetMapping(value="/statistique")
    @ResponseBody()
    Iterable<Object> doStatistique()
    {
        return operationsServiceImpl.operationsStat(new Long(selectedCentre)); 
    }

Operations类中有一个字段

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Target Name="BuildProjectReferences" BeforeTargets="BuildGenerateSources">
    <MsBuild Projects="@(ProjectReference)"
             Properties="Configuration=$(Configuration);Platform=$(Platform)"/>
  </Target>
</Project>

但查询不返回该字段的任何值。

相同 
  ...
  <Import Project="$(VCTargetsPath)\Microsoft.Cpp.targets" /> <!-- this is near the bottom already -->
  <Import Project="..\BuildProjectReferences.targets" /> !<-- add this -->
  ...
</Project>

查询中没有列guichetId，而您的private Date dateOperations; 在类中没有映射字段。

答案 2 :(得分：0)

似乎@Query(value="select o.guichet,count(*) from OPERATIONS o ..正在返回Guichet个对象的列表，但您期望List<Operations>。

一个选项是为您的Operations静态创建外部pojo（例如使用包名：com.myorg.model）

package com.myorg.model;
 public class OperationsStas {
  private Guichet guichet;
  private Long   count;

  public OperationsStas(Guichet guichet, Long count) {
    this.guichet = guichet;
    this.count  = count;
  }

}

回复可能是这样的：

@Repository
public interface OperationsRepository extends CrudRepository<Operations, Long> {

    @Query(value="select new com.myorg.model.com.myorg.model.OperationsStats(o.guichet,count(*)) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) " + 
            "and c.centre_id=?1 and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET " + 
            "group by o.guichet",nativeQuery=true)
    List<OperationsStas> operationsStat( Long centreId);

而且控件必须改变

@Override
    public List<OperationsStas> operationsStat(Long centreId) {
        return operationsRepository.operationsStat(centreId);
    }


@GetMapping(value="/statistique")
    @ResponseBody()
    List<OperationsStas> doStatistique()
    {
        return operationsServiceImpl.operationsStat(new Long(selectedCentre)); 
    }

希望它可以帮到你。
