我想根据与其他列和其他表的值比较更新closed_date列中的值.我用Oracle合并到声明中.但它给了我一个错误:
错误:ORA-00969:缺少ON关键字
我不确定出了什么问题.我想念什么吗？以下是我的脚本:
MERGE INTO PR_DMN dmn
USING (select alg.PR_DMN_ID, alg.PR_ACTIVITY_ID, alg.ACTIVITY_TS from PR_ACTIVITY_LOG) alg
ON dmn.PR_DMN_ID = alg.PR_DMN_ID
-- update
WHEN MATCHED THEN
UPDATE SET dmn.CLOSED_DATE =
(CASE
WHEN alg.PR_ACTIVITY_ID IN ('10009', '10010', '10011', '10013') THEN alg.ACTIVITY_TS
WHEN alg.PR_ACTIVITY_ID = '10005' AND dmn.CONT_RESP_TS <= dmn.CONT_RESP_DUE_TS THEN dmn.CONT_RESP_TS
WHEN alg.PR_ACTIVITY_ID = '10008' AND dmn.CORR_RESP_TS <= dmn.CORR_RESP_DUE_TS THEN dmn.CORR_RESP_TS
ELSE dmn.CLOSED_DATE
END)
