Question

I’m trying to delete a row of data across two tables. I have the following code which isn’t working:

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

I get the error message:

“SQL command not properly ended”

Would really appreciate some help as I am struggling to get to grips with Oracle.

You can’t do it with a join. DELETE FROM has to target a single table. You could do this:

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';
