데이터를 unpivoting 한 후 삽입하고 싶습니다. 명령문은 병합 statemenet이어야합니다. 그러나 ora-30926 오류가 발생하며 해결 방법을 찾을 수 없습니다. 여기에 데이터 테이블ORA-30926 : 원본 테이블에 안정된 행 집합을 가져올 수 없습니다.
는 :
------------------------------------------------------------------------------------
|Employee_id | work_experience_1 | work_experience_2 | work_experience_3 | language |
-------------------------------------------------------------------------------------
| 123 | C&S | Deloitte | TCS | FI |
| 211 | E&Y | Microsoft | | FI |
| 213 | C&S | | | FI |
-------------------------------------------------------------------------------------
----------------------------------
|Employee_id | work_experience |
----------------------------------
| 123 | C&S |
| 123 | Deloitte |

다음은 내가 수행 한 작업입니다. 삽입 부분은 정상적으로 작동하지만 업데이트 부분은 실패합니다.
MERGE INTO arc_hrcs.user_multi_work_exp work_exp
USING (SELECT user_id, work_experience_lang, work_exp_fi FROM
(SELECT ext.user_id, tmp_work.employee_id, tmp_work.work_experience_1, tmp_work.work_experience_2, tmp_work.work_experience_3, tmp_work.work_experience_4, tmp_work.work_experience_5, tmp_work.work_experience_6, tmp_work.work_experience_7, tmp_work.work_experience_8, tmp_work.work_experience_9, tmp_work.work_experience_10, tmp_work.work_experience_lang FROM arc_hrcs.hr_extension_data ext
JOIN aa_work_exp_tmp tmp_work ON tmp_work.employee_id = ext.employee_id)
UNPIVOT (work_exp_fi FOR work_code IN (work_experience_1 AS 'a', work_experience_2 AS 'b', work_experience_3 AS 'c', work_experience_4 AS 'd', work_experience_5 AS 'e', work_experience_6 AS 'f', work_experience_7 AS 'g', work_experience_8 AS 'h', work_experience_9 AS 'i', work_experience_10 AS 'j'))) r
ON (work_exp.user_id = r.user_id AND r.work_experience_lang LIKE '%FI%')
WHEN NOT MATCHED THEN
INSERT (work_exp.user_id, work_exp.work_experience_fi)
VALUES (r.user_id, r.work_exp_fi)
WHEN MATCHED THEN
UPDATE SET work_exp.work_experience_fi = r.work_exp_fi
어떻게 작동합니까? 사전에 건배 :-)
