如何解决 Oracle Apex 中的无效列错误？

Question

I am trying to add a plsql script that will update a event after "Apply Changes" button is pressed in a form. So I added a new "Dynamic Action" to click event of that button, set the action to "Execute PL/SQL CODE" and wrote the following script in "PL/SQL Code" section

BEGIN
UPDATE EVENT
SET START_DATE = :P53_START_DATE,
END_DATE = :P53_END_DATE,
START_TIME = :P53_START_TIME,
END_TIME = :P53_END_TIME,
DESCRIPTION = :P53_DESCRIPTION,
WHERE EVENT_ID = :P53_EVENT_ID;
END;
/

But I keep getting this error when I hit "Apply Changes"

Is there anything wrong in the way I am selection the values from the fields using "P53_....."?

How may I solve resolve this issue?

Answer 1

Your update statement references :P53_NEW.EVENT_NAME for the table column START_DATE . That cannot be right. Replace it with the correct variable.

Answer 2

there are several things wrong with this code:

BEGIN
UPDATE EVENT
SET START_DATE = :P53_START_DATE, << suggest using TO_DATE(:P53_START_DATE,'<your date format mask>') instead
END_DATE = :P53_END_DATE, << suggest using TO_DATE(:P53_END_DATE,'<your date format mask>') instead
START_TIME = :P53_START_TIME,
END_TIME = :P53_END_TIME,
DESCRIPTION = :P53_DESCRIPTION, << this comma makes statement fail
WHERE EVENT_ID = :P53_EVENT_ID; 
END;
/ << trailing slash not needed

But as I said in the comments, are you sure you need a dynamic action for this? The "apex way" of doing anything on a page submit is to execute pl/sql code in page processes on submit. Dynamic actions are designed to be used if code needs to be executed without submitting the case. This is just a comment, it is unrelated to your actual question.
