一.遍歷數組
create or replace procedure coco3 as
type t_Test is table of varchar2(10);
test t_test:=t_test('A','B','C','D','E','F','G','H','J','K','L');
begin
for i in 1 .. test.count loop
dbms_output.put_line(test(i));
end loop;
end;
二.遍歷遊標
方式一:
create or replace procedure CoCo2 as
cursor cur_n is select * from users where user_id like 'EDP%';
v_row users%rowtype;
begin
open cur_n;
loop
fetch cur_n into v_row;
exit when cur_n%notfound;
dbms_output.put_line('user_id:'||v_row.user_id||'name:'||v_row.name);
end loop;
close cur_n;
end ;
方式二:
create or replace procedure CoCo as
cursor cur_name is select user_id,name as usr_name from users where user_id like 'EDP%';
begin
for cur in cur_name loop
begin
dbms_output.put_line(cur.user_id||'-'||cur.usr_name);
end;
end loop;
end ;
三:遍歷數據表
create or replace procedure coco4 as
type t_users is table of users%rowtype;
v_user t_users;
begin
select * bulk collect into v_user from users where user_id like 'EDP%';
if v_user.count>0 then
for i in 1 .. v_user.count loop
dbms_output.put_line('haha:'||v_user(i).name);
end loop;
end if;
end;
