错误位置: 27 Return: 1730 - ORA-01730: 指定的列名数目无效

Question

我需要帮助使用 PeopleTools Application Designer 在 PeopleSoft 中创建视图。当运行在 ORACLE SQL Developer 中下面的视图 SQL 时，它选择得非常好，但是当我在 App Designer 中将其创建为视图时，出现以下错误：

Error: UM_7902_VW - SQL Error. Error Position: 27 Return: 1730 - ORA-01730: invalid number of column names specified.

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

如果能得到任何帮助，我将不胜感激。谢谢！

Answer 1

看起来你从它的前一个版本中获取了 create view some_view (col1, col2, ..., coln) as，修改了你发布的 select 声明（添加或删除了一些列）并且 - 一旦你把它粘在一起 - 的数量列不再匹配。

最简单的方法是让 Oracle 来做，即不要命名列：

create view some_view as
  select <your select goes here>

不过，请注意列名 select returns；你不能有像

这样的东西

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

因为列查询 returns 必须有它们的别名。

Answer 2

在 App 设计工具中为记录建模时：记录定义中的字段数量是否与 select SQL 中的字段数量相同？这些必须匹配，否则在 App Designer 中构建时会出现此错误。
