Oracle動態游標實現動態SQL迴圈遍歷

動態游標可以遍歷動態的表，

格式：

type 游標型別 is ref cursor;  --定義乙個動態游標

游標名　　游標型別;

需要注意的是，動態游標的定義，

在普通儲存過程中：需要放在 is 後面的第一行。

動態游標通過：open 游標 for 字串，形式使用，遍歷。

create or replace procedure p_test_sql 

is    
type ref_cursor_type is ref cursor;  --定義乙個動態游標     
tablename varchar2(200) default 'ess_client';    
v_sql varchar2(1000);    
mobile varchar2(15);    
usrs ref_cursor_type;    
begin    
--使用連線符拼接成一條完整sql     
v_sql := 'select usrmsisdn from '||tablename||' where rownum < 11';    
--開啟游標     
open usrs for v_sql ;    
loop    
fetch usrs into mobile;     
exit when usrs%notfound;    
insert into tmp(usrmsisdn) values(mobile);    
end loop;    
close usrs;    
commit;    
end p_test_sql;
