从 blob 插入二进制 xml

Question

尝试将数据从具有 blob 列的 table 插入到具有二进制 xml 列的 table 列

来源table

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

目标table

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

所以我尝试如下插入数据，但失败了

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

我正在关注的文档是 oracle 文档（文档 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

以下是 oracle 文档中的几行

” 使用 insert select 作为语法将数据从 scott.tb blob 移动到 scott.po_bin XMLType table 存储为二进制 XML

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

1 row created.

SQL> select * from po_bin;

尝试编辑代码，稍作改动仍然失败，出现其他错误编号

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

Answer 1

此失败的原因是 table 包含一些无效的 XML 数据。因此，在将数据插入 XML 二进制列时，某些行的验证失败。所以这不能在 table 上完成。但根据 oracle 文档，我的步骤是正确的。

从 blob 插入二进制 xml

inserting into binary xml from blob

xml

xmltype

insert-into
