我正在开发Spring Data JPA示例。在此示例中，我使用本地查询来进行RIGHT OUTER JOIN，因为两个数据库之间没有任何关系。
我正在使用以下本地查询：
@Query(value = "SELECT m.ACC_NUM, m.CUSTOMER_ID AS CID, CAST(COUNTRY_CODE AS VARCHAR2(3)) AS COUNTRY_CODE, CAST(BUSINESS_REGION_CODE AS VARCHAR2(2)) AS BUSINESS_REGION_CODE, l.LOCATION_NAME "
+ "FROM AA_TABLE m RIGHT OUTER JOIN BB_TABLE l ON (m.CUSTOMER_ID = l.BB_ID)"
+ "WHERE m.LEVEL_NUMBER = 20 AND m.ACC_NUM IS NOT NULL AND m.CUSTOMER_ID "
+ "IS NOT NULL AND (m.end_date IS NULL OR m.end_date > sysdate) AND ROWNUM <=5 ", nativeQuery = true)
List<CustomEntity> findByXXXXXXXX();
我正在使用Cistom Model类
public class CustomEntity{
private BigDecimal ACC_NUM;
private BigDecimal CUSTOMER_ID;
private String COUNTRY_CODE;
private String BUSINESS_REGION_CODE;
private String LEGAL_NAME;
}
错误：
