怎么在oracle建一个存储过程来遍历数组,新手求解
建一个存储过程
定义一个一维数组 Test{A,B,C,D,E,F,G,H,J,K,L}
怎么样用循环遍历数组,然后输出

新手求解

------解决方案--------------------
SQL code
create or replace procedure p_test 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 test.first .. test.last loop
dbms_output.put_line(test(i));
end loop;
end;
/
set serverout on
exec p_test;
