错误位置：27返回：1730 - ORA-01730：指定的列名无效

Question

我需要帮助使用PeopleTools Application Designer在PeopleSoft中创建视图。在ORACLE SQL Developer中运行下面的视图SQL时，它选择完全正常但是当我在App Designer中将其创建为视图时，我得到以下错误：

错误：UM_7902_VW - SQL错误。错误位置：27返回：1730 - ORA-01730：指定的列名无效。

这是我的sql：

SELECT A.EMPLID, B.NAME, A.ADM_APPL_NBR, C.ADMIN_FUNCTION, A.STDNT_CAR_NBR, 
A.ACAD_CAREER, D.APPL_PROG_NBR, D.ADMIT_TERM, C.CHECKLIST_CD, E.DESCRSHORT, 
C.CHECKLIST_STATUS, C.STATUS_DT, C.DUE_DT AS C_DUE_DT, C.COMM_COMMENTS, 
C.SEQ_3C, F.CHKLST_ITEM_CD,
G.DESCR, F.ITEM_STATUS, F.STATUS_DT, F.DUE_DT AS F_DUE_DT, F.RESPONSIBLE_ID
FROM PS_ADM_APPL_DATA A
JOIN PS_PERSON_NAME B ON B.EMPLID = A.EMPLID
JOIN PS_PERSON_CHECKLST C ON C.COMMON_ID = A.EMPLID
JOIN PS_ADM_APPL_PROG D ON D.EMPLID = A.EMPLID
AND D.EMPLID = A.EMPLID
AND D.ACAD_CAREER= A.ACAD_CAREER
AND D.STDNT_CAR_NBR= A.STDNT_CAR_NBR
AND D.ADM_APPL_NBR= A.ADM_APPL_NBR
AND D.EFFDT = 
(SELECT MAX(D2.EFFDT) FROM PS_ADM_APPL_PROG D2
WHERE D.EMPLID = D2.EMPLID
AND D.ACAD_CAREER = D2.ACAD_CAREER
AND D.STDNT_CAR_NBR = D2.STDNT_CAR_NBR
AND D.ADM_APPL_NBR = D2.ADM_APPL_NBR
AND D.APPL_PROG_NBR = D2.APPL_PROG_NBR
AND D2.EFFDT <= SYSDATE)
AND D.EFFSEQ =
(SELECT MAX(D3.EFFSEQ) FROM PS_ADM_APPL_PROG D3
WHERE D.EMPLID = D3.EMPLID
AND D.ACAD_CAREER = D3.ACAD_CAREER
AND D.STDNT_CAR_NBR = D3.STDNT_CAR_NBR
AND D.ADM_APPL_NBR = D3.ADM_APPL_NBR
AND D.APPL_PROG_NBR = D3.APPL_PROG_NBR
AND D.EFFDT <= D3.EFFDT)
JOIN PS_CS_CHKLST_TBL E ON E.CHECKLIST_CD = C.CHECKLIST_CD
AND E.EFFDT = (SELECT MAX(E2.EFFDT) FROM PS_CS_CHKLST_TBL E2 WHERE 
E2.INSTITUTION = E.INSTITUTION AND E2.CHECKLIST_CD = E.CHECKLIST_CD)
AND E.EFF_STATUS = 'A'
JOIN PS_PERSON_CHK_ITEM  F ON F.COMMON_ID = C.COMMON_ID
AND F.SEQ_3C = C.SEQ_3C
JOIN PS_SCC_CKLSITM_TBL  G ON G.CHKLST_ITEM_CD = F.CHKLST_ITEM_CD
AND G.EFF_STATUS = 'A'
AND G.EFFDT = (SELECT MAX(G2.EFFDT) FROM PS_SCC_CKLSITM_TBL  G2 WHERE 
G2.CHKLST_ITEM_CD = G.CHKLST_ITEM_CD)
JOIN PS_TERM_TBL H ON H.INSTITUTION = E.INSTITUTION
AND H.ACAD_CAREER = A.ACAD_CAREER

我将不胜感激任何帮助。谢谢！

Answer 1

在App Designer中对记录建模时：您在选择SQL中的记录定义中是否有相同数量的字段？这些必须匹配，否则在App Designer中构建时会出现此错误。

Answer 2

看起来好像你从之前的一个版本中获取了create view some_view (col1, col2, ..., coln) as，修改了你发布的select语句（添加或删除了一些列），并且 - 一旦你将它们粘在一起 - 列数就不再匹配了。

最简单的方法是让Oracle这样做，即不要命名列：

create view some_view as
  select <your select goes here>

虽然，注意列名select返回;你不能拥有类似的东西

select max(some_value),  --> this - must have an alias
       my_name

因为列查询返回必须具有其别名。
