Question

你能帮我写一个PLSQL代码来传递一个变量的'多个输入值'吗？请帮助我如何使用Record类型，对象和构造函数来编写Anonymous PLSQL块。

谢谢，

以下是一种方式：

HR@XE> CREATE OR REPLACE TYPE NUM_ARRAY AS TABLE OF NUMBER;
  2  /

Type created.

HR@XE> create or replace procedure demo_sp (
  in_array in num_array,
  out_sum out number
  )
  is
  BEGIN
  out_sum := 0;
  for i in 1 ..in_array.count loop
  out_sum := out_sum + in_array(i);
  END LOOP;
 END;
 /

Procedure created.

HR@XE> DECLARE
total  NUMBER;
nos NUM_ARRAY;
BEGIN
SELECT ROWNUM BULK COLLECT  INTO nos  FROM dual CONNECT BY ROWNUM<=5;
FOR I IN 1 .. nos.COUNT LOOP
dbms_output.put_line(nos(i));
end loop;
demo_sp(nos,total);
dbms_output.put_line('Total is: '||total);
END;
/
