我有一堆表需要链接在一起，目的是更新ub_gl_movement表中的名称和地址（列出的相关列）。
|ub_gl_movement|
:-------------------------------------------------------------------------------------------------:
|UBGL_UBCT_CONTRACT_ID|UBGL_UBIN_INVESTMENT_ID|UBGL_PAYEE_NAME|ADDR_1 |ADDR_2|ADDR_3|SUBURB |
:-------------------------------------------------------------------------------------------------:
|194875 |000000Z0000480 |John Smith |123 Some St|(null)|(null)|Somewhere|
zz_person表如下
|zz_person|
:-------------------------------------------:
|ZZPD_PERSON_ID|ZZPD_FIRST_NAME|ZZPD_SURNAME|
:-------------------------------------------:
|21916908 |Bill |Jones |
地址表如下
|ADDRESS|
:-----------------------------------------------------------:
|ZZAD_ZZPD_PERSON_ID|ZZAD_LINE_1 |ZZAD_LINE_2|ZZAD_LINE_3|
:-----------------------------------------------------------:
|21916908 |456 Main Street|(null) |(null) |
没有办法按原样链接这些表，因此我尝试使用INVESTMENT_ID和PERSON_ID通过另一个名为zz_investment_person的表进行链接。
编辑：添加DESC UB_INVESTMENT

我需要更新ub_gl_movement表，以便将UBGL_PAYEE_NAME设置为Bill Jones，地址为456 Main Street。我的问题是
UPDATE
(
SELECT G.UBGL_PAYEE_NAME PAYEE_NAME,
P.ZZPD_FIRST_NAME F_NAME,
P.ZZPD_SURNAME L_NAME
FROM UTB.UB_GL_MOVEMENT G
JOIN UTB.UB_INVESTMENT I
ON G.UBGL_UBIN_INVESTMENT_ID = I.UBIN_INVESTMENT_ID
JOIN UTB.ZZ_INVESTMENT_PERSON IP
ON IP.ZZIP_INVESTMENT_ID = I.UBIN_INVESTMENT_ID
JOIN UTB.ZZ_PERSON P
ON P.ZZPD_PERSON_ID = IP.ZZIP_ZZPD_PERSON_ID
WHERE G.UBGL_PAYEE_NAME IS NOT NULL
)
SET PAYEE_NAME = F_NAME || ' ' || L_NAME;
但是我收到了错误
SQL Error: ORA-01779: cannot modify a column which maps to a non key-preserved table
01779. 00000 - "cannot modify a column which maps to a non key-preserved table"
*Cause: An attempt was made to insert or update columns of a join view which
map to a non-key-preserved table.
*Action: Modify the underlying base tables directly.
如果我运行此查询
UPDATE UTB.UB_GL_MOVEMENT G
SET G.UBGL_PAYEE_NAME =
(SELECT CASE WHEN (UPPER(ZZPD_REF_TITLE) = 'EST OF')
THEN SUBSTR(ZZPD_REF_TITLE, 1, 3) || ' ' || ZZPD_FIRST_NAME || ' ' || ZZPD_SURNAME
WHEN (ZZPD_REF_TITLE IS NOT NULL AND ZZPD_FIRST_NAME IS NOT NULL AND ZZPD_SURNAME IS NOT NULL )
THEN ZZPD_REF_TITLE || ' ' || ZZPD_FIRST_NAME || ' ' || ZZPD_SURNAME
WHEN (ZZPD_REF_TITLE IS NULL AND ZZPD_FIRST_NAME IS NOT NULL AND ZZPD_SURNAME IS NOT NULL)
THEN ZZPD_FIRST_NAME || ' ' || ZZPD_SURNAME
ELSE 'SIR / MADAM' END
FROM UTB.ZZ_PERSON P
JOIN UTB.ZZ_INVESTMENT_PERSON IP
ON P.ZZPD_PERSON_ID = IP.ZZIP_ZZPD_PERSON_ID
JOIN UTB.UB_INVESTMENT I
ON G.UBGL_UBIN_INVESTMENT_ID = I.UBIN_INVESTMENT_ID
AND ROWNUM = 1
)
WHERE G.UBGL_PAYEE_NAME IS NOT NULL;
我收到了不同的错误
Error at Command Line:14 Column:21
Error report:
SQL Error: ORA-00904: "G"."UBGL_UBIN_INVESTMENT_ID": invalid identifier
00904. 00000 - "%s: invalid identifier"
我还没有更新此查询中的地址表。我想我先从名字开始。
非常感谢任何输入：）
编辑2 - 我已将第二次更新查询更改为
UPDATE UTB.UB_GL_MOVEMENT G
SET G.UBGL_PAYEE_NAME = (SELECT CASE WHEN (UPPER(ZZPD_REF_TITLE) = 'EST OF')
THEN SUBSTR(ZZPD_REF_TITLE, 1, 3) || ' ' || ZZPD_FIRST_NAME || ' ' || ZZPD_SURNAME
WHEN (ZZPD_REF_TITLE IS NOT NULL AND ZZPD_FIRST_NAME IS NOT NULL AND ZZPD_SURNAME IS NOT NULL )
THEN ZZPD_REF_TITLE || ' ' || ZZPD_FIRST_NAME || ' ' || ZZPD_SURNAME
WHEN (ZZPD_REF_TITLE IS NULL AND ZZPD_FIRST_NAME IS NOT NULL AND ZZPD_SURNAME IS NOT NULL)
THEN ZZPD_FIRST_NAME || ' ' || ZZPD_SURNAME
ELSE 'SIR / MADAM' END
FROM UTB.ZZ_PERSON P
JOIN UTB.ZZ_INVESTMENT_PERSON IP ON P.ZZPD_PERSON_ID = IP.ZZIP_ZZPD_PERSON_ID
JOIN UTB.UB_INVESTMENT I ON I.UBIN_INVESTMENT_ID = IP.ZZIP_INVESTMENT_ID
JOIN UTB.UB_GL_MOVEMENT GMT ON GMT.UBGL_UBIN_INVESTMENT_ID = I.UBIN_INVESTMENT_ID
WHERE ROWNUM = 1
)
WHERE G.UBGL_PAYEE_NAME IS NOT NULL;
确实执行，但所有PAYEE_NAME都是相同的，因此它似乎从ZZ_PERSON表中取出第一行并将其用于所有行，而不是在表中搜索相关的ID / Name组合。如果我删除rownum = 1，我会收到错误
SQL Error: ORA-01427: single-row subquery returns more than one row
01427. 00000 - "single-row subquery returns more than one row"
