跨两个表删除整行（内连接？）

Question

我正在尝试跨两个表删除一行数据。我有以下代码无效：

DELETE
FROM PROCESS_OWNER.ARTIFACTS
JOIN PROCESS_OWNER.ARTIFACT_METADATA
ON ARTIFACTS.ARTIFACT_ID = ARTIFACT_METADATA.ARTIFACT_ID
WHERE ARTIFACT_LABEL = 'getTest'

我收到错误消息：

  

“SQL命令未正确结束”

当我努力想要掌握Oracle时，真的会感激一些帮助。

你不能通过加入来做到这一点。 DELETE FROM必须以单个表为目标。你可以这样做：

DELETE FROM PROCESS_OWNER.ARTIFACT_METADATA WHERE ARTIFACT_ID = (SELECT ARTIFACT_ID FROM PROCESS_OWNER.ARTIFACTS WHERE ARTIFACT_LABEL = 'getTest');
DELETE FROM PROCESS_OWNER.ARTIFACTS WHERE ARTIFACT_LABEL = 'getTest';
