@NativeQuery ORA-00942：表或视图不存在 - SpringBoot

Question

所以我正在尝试进行本机查询以从 Oracle 数据库中获取一些数据，但我不断收到此错误：

java.sql.SQLSyntaxErrorException: ORA-00942: 表或视图没有 存在

我的查询是这个：

@Query(
        value = "select d.* from DEFAULT_GROUP d " +
            "inner join COMPANIA_DEFAULT_GROUP cd on d.ID = cd.DEFAULT_GROUP_ID " +
            "inner join COMPANIA c on c.ID = cd.COMPANIA_ID " +
            "where c.ID = cast(:companiaId AS NUMBER) and lower(d.NAME) like lower(cast(:dgName AS varchar(255))) ORDER BY d.NAME ASC " ,
        nativeQuery = true
    )
    List<DefaultGroup> findDefaultGroupsByNameLike(@Param("companiaId") Long companiaId,@Param("dgName") String dgName);

我的实体Compania是这样的：

@Entity(name = "Compania")
@Table(
    name = "compania"
)
public class Compania {
    @Id
    @SequenceGenerator(
        name = "compania_sequence",
        sequenceName = "compania_sequence",
        allocationSize = 1
    )
    @GeneratedValue(
        strategy = GenerationType.AUTO,
        generator = "compania_sequence"
    )
    @Column(
        nullable = false
    )
    private Long id;


    @Column(
        name = "name",
        nullable = false,
        unique = true
    )
    private String name;

    @Column(
        name = "dominio"
    )
    private String dominio;

    @Column(
        name = "altas"
    )
    private String altas;

    @Column(
        name = "bajas"
    )
    private String bajas;

    @OneToMany(
        cascade = CascadeType.ALL,
        fetch = FetchType.LAZY,
        orphanRemoval = true
    )
    private List<DefaultGroup> default_group;

    @OneToMany(
        cascade = CascadeType.ALL,
        fetch = FetchType.LAZY,
        orphanRemoval = true
    )
    private List<Office> office;

    public Compania() {
    }

    public Compania(String name, String dominio, String altas, String bajas, List<DefaultGroup> defaultGroup, List<Office> office) {
        this.name = name;
        this.dominio = dominio;
        this.altas = altas;
        this.bajas = bajas;
        this.default_group = defaultGroup;
        this.office = office;
    }
    ... Getters and Setters...

而我的实体Default Group是这样的：

@Entity
@Table
public class DefaultGroup {
    @Id
    @SequenceGenerator(
        name = "defaultGroup_sequence",
        sequenceName = "defaultGroup_sequence",
        allocationSize = 1
    )
    @GeneratedValue(
        strategy = GenerationType.SEQUENCE,
        generator = "defaultGroup_sequence"
    )
    @Column(
        nullable = false
    )
    private Long id;

    @Column(
        name = "name",
        nullable = false
    )
    private String name;

    @Column(
        name = "path",
        nullable = false
    )
    private String path;

    public DefaultGroup() {
    }

    public DefaultGroup(String name, String path) {
        this.name = name;
        this.path = path;
    }
   ... Getters and Setters...

当我检查 Azure Insights 中的故障时，我发现它正在尝试这个 SQL：

/* 动态原生 SQL 查询/ select d. from DEFAULT_GROUP d inner 在 d.ID = cd.DEFAULT_GROUP_ID 内加入 COMPANIA_DEFAULT_GROUP cd 在 c.ID = cd.COMPANIA_ID 上加入 COMPANIA c，其中 c.ID = cast(? AS NUMBER) 和 lower(d.NAME) like lower(cast(?AS varchar(?))) ORDER BY d.NAME ASC

然后抛出一个500 internal server error和oracle错误代码ORA-00942: table or view does not exist

我在错误堆栈的末尾也看到了这个错误：

Caused by: Error : 942, Position : 141, Sql = /* dynamic native SQL query */ select d.* from DEFAULT_GROUP d inner join COMPANIA_DEFAULT_GROUP cd on d.ID = cd.DEFAULT_GROUP_ID inner join COMPANIA c on c.ID = cd.COMPANIA_ID where c.ID = cast(:1  AS NUMBER) and lower(d.NAME) like lower(cast(:2  AS varchar(255))) ORDER BY d.NAME ASC , OriginalSql = /* dynamic native SQL query */ select d.* from DEFAULT_GROUP d inner join COMPANIA_DEFAULT_GROUP cd on d.ID = cd.DEFAULT_GROUP_ID inner join COMPANIA c on c.ID = cd.COMPANIA_ID where c.ID = cast(? AS NUMBER) and lower(d.NAME) like lower(cast(? AS varchar(255))) ORDER BY d.NAME ASC , Error Msg = ORA-00942: table or view does not exist

我的另一个名为 OFFICE 的表也发生了同样的事情

数据库拥有的表是：

• 公司
• COMPANIA_DEFAULT_GROUP（两个实体的 ID）
• COMPANIA_OFFICE（两个实体的 ID）
• DEFAULT_GROUP
• 办公室

我怀疑这里存在某种区分大小写的表命名问题。为了安全起见，请使用@Entity注解显式设置表name：

@Entity(name = "COMPANIA")
public class Compania {
    ...
}

@Entity(name = "DEFAULT_GROUP")
public class DefaultGroup {
    ...
}

@Entity(name = "COMPANIA_DEFAULT_GROUP")
public class CompanyDefaultGroup {
    ...
}
