从blob插入二进制xml

Question

尝试将具有blob列的表中的数据插入到具有二进制xml列的表中

源表

desc "T24"."FBNK_ACCOUNT_CLOSED"; 
Name Null? Type 
----------------------------------------- -------- ---------------------- 
------ 
RECID NOT NULL VARCHAR2(255) 
XMLRECORD BLOB 

目标表

SQL> desc "T24"."FBNK_ACCOUNT_CLOSED_TEMP"; 
Name Null? Type 
----------------------------------------- -------- ---------------------- 
------ 
RECID NOT NULL VARCHAR2(255) 
XMLRECORD XMLTYPE STORAGE BINARY

所以我试图插入数据如下，但它失败了

SQL> insert into "T24"."FBNK_ACCOUNT_CLOSED_TEMP" select RECID,XMLRECORD 
from "T24"."FBNK_ACCOUNT_CLOSED" where rownum<10; 

insert into "T24"."FBNK_ACCOUNT_CLOSED_TEMP" select RECID,XMLRECORD from 
"T24"."FBNK_ACCOUNT_CLOSED" where rownum<10 
* 
ERROR at line 1: 
ORA-00932: inconsistent datatypes: expected - got BLOB

我关注的文件是oracle文件（Doc ID 1405457.1）

https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=309572821111227&parent=SrDetailText&sourceId=3-19827644581&id=1405457.1&_afrWindowMode=0&_adf.ctrl-state=1qwexs4zw_510

下面是oracle文档中的几行

“使用insert select as syntax将数据从scott.tb blob移动到存储为二进制XML的scott.po_bin XMLType表中

SQL> insert into po_bin select xmltype(bc, 873) from scott.tb;

1 row created.

SQL> select * from po_bin;

SYS_NC_ROWINFO$

尝试编辑代码，几乎没有改动仍然没有其他错误号

insert into "T24"."FBNK_ACCOUNT_CLOSED_TEMP" select recid, 
xmltype(xmlrecord, 873) from "T24"."FBNK_ACCOUNT_CLOSED" where rownum<1000 
* 
ERROR at line 1:

Answer 1

此失败的原因是该表包含一些无效的XML数据。因此，当将数据插入XML二进制列时，某些行的验证失败。所以这个不能在这张桌子上完成。但根据oracle文档，我的步骤是正确的。
