执行存储过程的执行方式有多少

procedure:

CREATE OR REPLACE PROCEDURE DOUBLEN (N IN OUT number) IS
BEGIN
    N := N * 2;
END;

对于上述程序执行目的,我写了以下pl / sql代码

DECLARE
    R INT;
BEGIN
    R := 7;
    DBMS_OUTPUT.PUT_LINE('BEFORE CALL R IS: ' || R);
    DOUBLEN(R);
    DBMS_OUTPUT.PUT_LINE('AFTER CALL R IS: ' || R);

Procedure:

create or replace procedure proc_in_out
 (n in out number)
 as 
 begin
 dbms_output.put_line('value of n before manipulation'||' '||n);
 n:=n*2;
 dbms_output.put_line('value of n after manipulation'||' '||n);
end proc_in_out;

---

  set serveroutput on;
     declare 
      n number;
      begin
      n:=2;
      proc_in_out(n);
    end;

---

    anonymous block completed
    value of n before manipulation 2
    value of n after manipulation 4

This will work try this......

这将尝试这个......
