訪问oracle数据链路的blob字段值

訪问照片表

select * from zp@dblink1 where a1='11111';

会报错：ora-22992 无法使用从远程表选择的LOB定位器

改为下面方法：

方法一：
 drop table temp
 Create  table temp as select * from zp@dblink1 where a1='002';
 select * from temp;

 方法二：

--创建表仅仅需运行一次
Create global temporary table temp on commit delete rows as select * from zp@zhplink where 1=2;
Create table temp2 as select * from temp where 1=2;

--能够多次运行insert

insert into temp select * from zp@zhplink where gmsfhm='140502199102260519';
insert into temp2 select * from temp;

commit;

select * from temp2;
