ORA-00904 Invalid Identifier - Update Statement With Two Tables - sql

Question

I'm working with PeopleSoft Campus Solutions, and we need to update about 22,000 rows of data. This is data between the tables of ACAD_PLAN_VW and ACAD_PROG. Students are listed on both, so their IDs match between the two.
Basically what we are trying to do is say that when the ID, academic career, student career number, effective sequence, and effective date match, AND where the academic plan (their degree, as stored on the ACAD_PLAN_VW) is a specific value, update the ACAD_PROG on the ACAD_PROG table to X value.
I tried to do some very interesting combinations of FROM statements, constantly getting errors. After some researching, I found out that SQLTools doesn't really like FROM statements within UPDATE statements, so I rewrote it to just make the connections manually. I'm assuming I'm doing this right, unless I need to reword it.
The statement I have is:
UPDATE PS_ACAD_PROG SET PS_ACAD_PROG.ACAD_PROG = 'UGDS'
WHERE PS_ACAD_PLAN_VW.EMPLID = PS_ACAD_PROG.EMPLID
AND PS_ACAD_PLAN_VW.ACAD_CAREER = PS_ACAD_PROG.ACAD_CAREER
AND PS_ACAD_PLAN_VW.STDNT_CAR_NBR = PS_ACAD_PROG.STDNT_CAR_NBR
AND PS_ACAD_PLAN_VW.EFFSEQ = PS_ACAD_PROG.EFFSEQ
AND PS_ACAD_PLAN_VW.EFFDT = PS_ACAD_PROG.EFFDT
AND PS_ACAD_PLAN_VW.ACAD_PLAN = 'DSTDS'
Theoretically, I would assume that this would update any student who has those connections. However, the error that I'm currently getting is as follows:
ORA-00904: "PS_ACAD_PLAN_VW"."ACAD_PLAN": invalid identifier
I have, as of yet, been unable to figure out the issue. I do have the correct access to view and update those fields, and the field does indeed exist.

Answer 1

Oracle doesn't know it should use the PS_ACAD_PLAN_VW table. Somehow you should reference it.
For example can you try this way?
UPDATE (
select
PS_ACAD_PROG.ACAD_PROG,
PS_ACAD_PLAN_VW.ACAD_PLAN
from
PS_ACAD_PROG,
PS_ACAD_PLAN_VW
where
PS_ACAD_PLAN_VW.EMPLID = PS_ACAD_PROG.EMPLID
AND PS_ACAD_PLAN_VW.ACAD_CAREER = PS_ACAD_PROG.ACAD_CAREER
AND PS_ACAD_PLAN_VW.STDNT_CAR_NBR = PS_ACAD_PROG.STDNT_CAR_NBR
AND PS_ACAD_PLAN_VW.EFFSEQ = PS_ACAD_PROG.EFFSEQ
AND PS_ACAD_PLAN_VW.EFFDT = PS_ACAD_PROG.EFFDT
)
SET
ACAD_PROG = 'UGDS'
WHERE
ACAD_PLAN = 'DSTDS'

Answer 2

Try to use the table which is not getting identified,by keeping in where clause so that you can use the select statement.That will help identifying the tables.

Answer 3

The following implementation should work:
UPDATE PS_ACAD_PROG
SET ACAD_PROG = 'UGDS'
WHERE ROWID IN(SELECT PROG.ROWID
FROM PS_ACAD_PROG PROG
, PS_ACAD_PLAN_VW PLAN
WHERE PLAN.EMPLID = PROG.EMPLID
AND PLAN.ACAD_CAREER = PROG.ACAD_CAREER
AND PLAN.STDNT_CAR_NBR = PROG.STDNT_CAR_NBR
AND PLAN.EFFSEQ = PROG.EFFSEQ
AND PLAN.EFFDT = PROG.EFFDT
AND PLAN.ACAD_PLAN = 'DSTDS');
