訪問照片表

select * from [email protected] where a1=‘11111‘;

會報錯：ora-22992 無法使用從遠端資料表選擇的LOB定位器

改為以下方法：

方法一：
 drop table temp
 Create  table temp as select * from [email protected] where a1=‘002‘;
 select * from temp;

 方法二：

--建立表只需執行一次
Create global temporary table temp on commit delete rows as select * from [email protected] where 1=2;
Create table temp2 as select * from temp where 1=2;

--可以多次執行insert

insert into temp select * from [email protected] where gmsfhm=‘140502199102260519‘;
insert into temp2 select * from temp;

select * from temp2;
