說明：下面的儲存過程在oracle817下全部通過測試，編譯和執行均是正確的
一、最簡單的乙個動態游標：
create or replace procedure test_cur
isstrsql1 varchar(1000);
type tcur is ref cursor;
cur tcur;
ac_where varchar2(100);
ac varchar2(100);
begin
ac_where := '(52228,52230)';
open cur for 'select bill_id from bill_main where bill_id in '|| ac_where;
loop
fetch cur into ac;
exit when cur%notfound;
dbms_output.put_line(ac);
end loop;
close cur;
end test_cur;
二、動態游標中使用動態的sql語句並執行：
create or replace procedure test_cur
(p_orgid_wins string)is
strsql1 varchar2(1000);
type my_curtype is ref cursor;
cur_1 my_curtype;--指示cur_1的型別為my_curtype，而my_curtype是游標型別
ac_where varchar2(100);
ac varchar2(100);
begin
ac_where := '(52228,52230)';
open cur_1 for 'select bill_id from bill_main where bill_id in '|| ac_where;--開啟動態游標
loop
fetch cur_1 into ac;
exit when cur_1%notfound;
strsql1:='delete bill_main where bill_id='||ac;
dbms_output.put_line(strsql1);
dbms_output.put_line(ac);
execute immediate strsql1;--執行乙個動態的sql語句
commit;
end loop;
close cur_1;
end test_cur;
三、動態游標中執行動態dql語句：
create or replace procedure test_cur
(p_orgid_wins string)is
strsql1 varchar2(1000);
strsql2 varchar2(1000);
type my_curtype is ref cursor;
cur_1 my_curtype;--指示cur_1的型別為my_curtype，而my_curtype是游標型別
ac_where varchar2(100);
t_to_orgid number;
t_bill_id number;
begin
ac_where := '(98978,98980)';
strsql1:='select bill_id,to_orgid from bill_main where bill_id in '|| ac_where;
dbms_output.put_line(strsql1);
open cur_1 for strsql1;--開啟動態游標
loop
fetch cur_1 into t_bill_id,t_to_orgid;
exit when cur_1%notfound;
dbms_output.put_line('t_to_orgid='||t_to_orgid);
strsql2:='delete bill_main where bill_id='||t_bill_id;
strsql2:=strsql2|| 'and start_no='||'16506';
dbms_output.put_line(strsql2);
dbms_output.put_line(t_bill_id);
execute immediate strsql1;--執行乙個動態的sql語句
commit;
end loop;
close cur_1;
end test_cur;

今天寫了個動態游標 使用傳入引數 關於游標分類以及用法 思路就是先拼好sql 然後開動態游標 oralce10g也支援正規表示式 呵呵 剛剛好可以實現動態傳入引數 procedure tj pda testdata v indicator in varchar is type rc is ref c...
