如何使用記錄類型，對象和構造函數在PLSQL中輸入多個輸入值？

Question

你能幫我寫一個PLSQL代碼來爲單個變量傳遞'多個輸入值'嗎？請幫助我如何使用Record type，object和constructors編寫Anonymous PLSQL塊。

謝謝你，

問候， Veeresh

這裏有一種方法：

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; 
/
