Spring JPAリポジトリ - 原因：org.hibernate.exception.SQLGrammarException：ResultSetを抽出できませんでした

Question

私はリポジトリを持ち、Postmanからこのリポジトリに直接アクセスしています。

Projectクラスは

@Data @Entity @Table(name = "PROJECT", schema = "DCS") public class Project implements Identifiable<Integer> { 
    @Id 
    @Column(name = "PRJ_I", nullable = false) 
    private Integer id; 

    @Column(name = "PRJ_NM") 
    private String projectName; 

    @OneToOne 
    @JoinColumn(name="PRJ_I") 
    private CcpaCustomerProjectGroup ccpaCustomerProjectGroup; 
} 

ProjectRepositoryはすでにコメントでJBが述べた

public interface ProjectRepository extends JpaRepository<Project, Integer>,JpaSpecificationExecutor<Project>, QueryDslPredicateExecutor<Project> { 

    @Query(value="select p.PRJ_I,p.PRJ_NM from CCPA_CUS_PRJ_GRP c,project p where c.CUS_PRJ_GRP_I = ?1 and c.PRJ_I = p.PRJ_I and p.PRJ_NM like ?2", nativeQuery = true) 
    List<Project> find(@Param("clientId") Integer clientId, @Param("projectName") String projectName); 

} 

Answer 1

あるCcpaCustomerProjectGroupが、これは重要な部分

@Data @Entity @Table(name = "CCPA_CUS_PRJ_GRP", schema = "DCS") public class CcpaCustomerProjectGroup implements Identifiable<Integer> { 
    @Id 
    @Column(name="CCPA_CUS_PRJ_GRP_I") 
    private Integer id; 

    @Column(name="CUS_PRJ_GRP_I") 
    private Integer customerProjectGroupId; 

    @Column(name="PRJ_I") 
    private Integer projectId; 

    /*@OneToOne 
    @PrimaryKeyJoinColumn 
    private Project project;*/ 
} 

ですですそのスタックトレース：DCS.PROJECTは、使用しているデータソースに存在し、そしてあなたがあなたのアプリケーションにして接続しているユーザーは、必要な助成金を持っていること、それを見るために

com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=RCON411.PROJECT, DRIVER=4.11.69

まず確認。

同様に、PROJECTテーブルが間違ったスキーマからアクセスしようとしているようです。アプリケーション内のDB2に接続するために使用しているユーザーは、DCSスキーマにアクセスできますか？その場合は、CURRENT_SCHEMAをDCSに設定する必要があります。
