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;

create or replace procedure ddgz1--訂單跟蹤

( 
p_flag varchar,--訂單型別
p_operate varchar,--操作型別
p_bh varchar --傳入的編號id)is
type ref_cursor_type is ref cursor;
v_cur_ckd ref_cursor_type;
begin
open v_cur_ckd for 'select v_erp,v_drp,v_jxsmc,v_jxs,v_dwmc,v_czr,v_jlsj from tmp_ddgz1'; 
fetch v_cur_ckd into v_erp,v_drp,v_jxsmc,v_jxs,v_dwmc,v_czr,v_jzsj;
while v_cur_ckd%found
loop 
insert into drpddgzjl2 (jlid,drp,erp,jxs,jxsmc,jlsj,gzjl,czr,bhid) values(sys_guid(),v_drp,v_erp,v_jxs,v_jxsmc,v_jzsj,v_dwmc||'受託代銷成品庫接收訂單，組織發貨',v_czr,'出庫單'||p_bh); 
fetch v_cur_ckd into v_erp,v_drp,v_jxsmc,v_jxs,v_dwmc,v_czr,v_jzsj;
end loop;
close v_cur_ckd;
end;
