Projektklasse ist

@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")

} 

CcpaCustomerProjectGroup ist

    @Id 
    @Column(name="CCPA_CUS_PRJ_GRP_I")

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

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

ProjectRepository ist

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

Wie bereits von JB in den Kommentaren erwähnt, dies ist der wichtige Teil von das Stack-Trace:

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

zunächst bestätigen, dass DCS.PROJECT in der Datenquelle mit dem Sie arbeiten, und dass der Benutzer in Ihrer Anwendung Sie eine Verbindung besteht, die notwendigen Zuschüsse hat es anzuzeigen.

Ähnlich sieht aus, als ob die PROJECT-Tabelle versucht, aus dem falschen Schema zuzugreifen. Hat der Benutzer, mit dem Sie in Ihrer App eine Verbindung zu DB2 herstellen, Zugriff auf das DCS-Schema? Und wenn dies der Fall ist, müssen Sie CURRENT_SCHEMA möglicherweise als DCS festlegen.
