I'm currently trying to copy the contents of a blob column from one table to another in Oracle Apex 5 and no matter what, it doesn't copy the BLOB data over, it leaves all those fields blank and it's driving my nuts.
Here is the PL/SQL I'm using to accomplish this as a process.
insert into ATTACHMENTS_AVAIL
("ADDED_FILE", "MIMETYPE", "FILENAME", "CONTRACTOR_ID", "DATE_ADDED", "TYPE")
select RESUME,
MIMETYPE,
FILENAME,
:P24_CONTRACTOR_ID,
sysdate,
'Resume'
from subs
where pkey = :P24_SUBS_PKEY;
Any idea what I'm missing here?
Here are the field types.
ADDED_FILE - BLOB
MIMETYPE - VARCHAR2
FILENAME - VARCHAR2
CONTRACTOR_ID - NUMBER
DATE_ADDED - DATE
TYPE - VARCHAR2
(...) it leaves all those fields blank
It means that WHERE
clause failed, completely:
SUBS.PKEY
whose value is equal to P24_SUBS_PKEY
item value, or P24_SUBS_PKEY
is empty How come? Because, even if every other value was NULL, SYSDATE
(you insert into DATE_ADDED
) and 'Resume' (which goes into TYPE
column) would be inserted. So, INSERT
failed because SELECT
failed because WHERE
doesn't work.
I presume you checked whether SUBS
table contains appropriate values. Therefore, I presume that P24_SUBS_PKEY
item doesn't contain anything. Perhaps you see the value on the screen, but - is it in session state? I guess not. Enable debugging and check the sessions state values after the process ends.
Saying that you wrote a process which should do the INSERT
- when does that process "fire"? The simplest way is, probably, when you push a button which submits the page. And, once you submit it, items' values are "stored" into session state. I suggest you to do that, just to make sure it actually works. Then you can improve the whole thing, if necessary.
