我想在取消數據後插入數據。該聲明需要成爲合併狀態網。但是，我得到了ora-30926錯誤，我無法弄清楚如何解決它。ORA-30926：無法在源表中獲得穩定的一組行
這裏的數據表：
------------------------------------------------------------------------------------
|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 |
-------------------------------------------------------------------------------------
所以先輸入數據之前，我需要UNPIVOT它。
----------------------------------
|Employee_id | work_experience |
----------------------------------
| 123 | C&S |
| 123 | Deloitte |
| 123 | TCS |
| 211 | E&Y |
| 211 | Microsoft |
| 213 | C&S |
----------------------------------
這是我所做的。插入部分工作正常，但更新部分失敗。
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
我該怎麼做才能使它工作？ 歡呼聲和thx提前:-)
