Question

我有表格列： xx_org

Org_name source_id source_owner

和另一张表： master_org

name，source_id，source_owner，class

现在我必须使用xx_org中的source_id来更新master_org中的所有source_id，因为xx_org和master_org中的任何组织名称都是常见的。对于不常见的人，不应该做任何事情。

我用过：

    update HR.master_org T1,XX_ORG T2 
set  T1.SOURCE_ID=T2.SOURCE_ID
    WHERE t2.ORG_NAME = t1.name ;

但这是错误的：

Error report:
SQL Error: ORA-00971: missing SET keyword
00971. 00000 -  "missing SET keyword"
*Cause:    
*Action:

看看其他帖子，我也尝试过：

UPDATE 
(select TABLE1.SOURCE_ID as old, TABLE2.SOURCE_ID as new
 from XX_ORG TABLE1
 INNER JOIN HR.master_org  table2
 ON table1.ORG_NAME = table2.name
) T
SET t.old = t.new

我得到了：

Error report:
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.

正如Update statement with inner join on Oracle

中所述

我尝试使用合并，因为其他查询没有工作，但即使显示1400行合并后，我也看不到我的行更新。我正在使用：

merge
INTO    hr.master_org trg
using   (
        SELECT  t1.rowid AS rid, t2.SOURCE_ID,t2.SOURCE_owner
        FROM    hr.master_org t1
        join    XX_ORG T2
        on      T1.ORGANIZATION_NAME = t2.ORG_NAME
        where   T1.ORGANIZATION_NAME = T2.ORG_NAME
       -- and t1.ORGANIZATION_NAME='TMI Operations, M1'
        ) src
ON      (trg.rowid = src.rid)
when matched then update
    set TRG.SOURCE_id = SOURCE_id,
    TRG.SOURCE_owner = SOURCE_owner;

sample data :
XX_ORG
source_id source_owner  org_name
EB73636   EBS           TMI

MASTER_ORG

source_id      source_owner  org_name
EB7363-30-JAN   FUSION         TMI

我想以这样的方式更新master_org

   source_id      source_owner  org_name
    EB73636        EBS            TMI

更新记录/合并时缺少set关键字也无法正常工作
