前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
<div class="codetitle"><a style="CURSOR: pointer" data="92879" class="copybut" id="copybut92879" onclick="doCopy('code92879')"> 代码如下:
<div class="codebody" id="code92879">
create or replace procedure Test5(o_cellphone in varchar2) is
v_cellphone cc_quiz_stat.cellphone %type;
v_name cc_quiz_stat %rowtype;
v_state cc_quiz_stat.state %type;
begin
declare
cursor cur_cc is
select
from cc_quiz_stat;
cursor cur_jc(v_n varchar2) is
select state from cc_quiz_stat;
begin
open cur_cc;
loop
fetch cur_cc
into v_name;
exit when cur_cc%notfound;
open cur_jc(o_cellphone);
loop
fetch cur_jc
into v_state;
exit when cur_jc %notfound;
if (o_cellphone = v_name.cellphone) then
return;
else
dbms_output.put_line('手机号' || v_name.cellphone || '省份' ||
v_state);
end if;
end loop;
close cur_jc;
end loop;
close cur_cc;
end;
end Test5;
执行结果
手机号18900000000省份全国
手机号18900000000省份南京
手机号18900000000省份天津
手机号18900000000省份 上海
手机号18900000000省份北京
