Oracle存储过程包含三部分：过程声明，执行过程部分，存储过程异常。

Oracle存储过程可以有无参数存储过程和带参数存储过程。 
一、无参程序过程语法

 create or replace procedure NoParPro
 as  ;
 begin
 ;
 exception     //存储过程异常
     ;
 end;
 

        二、带参存储过程实例

 create or replace procedure queryempname(sfindno emp.empno%type) as         sName emp.ename%type;         sjob emp.job%type; begin        .... exception          .... end;

 三、 带参数存储过程含赋值方式

create or replace procedure runbyparmeters  (isal in emp.sal%type,
                            sname out varchar,sjob in out varchar)
  as icount number;
  begin
       select count(*) into icount from emp where sal>isal and job=sjob;
       if icount=1 then
         ....
      else
         ....
       end if;
  exception
       when too_many_rows then
       DBMS_OUTPUT.PUT_LINE(‘返回值多于1行‘);
       when others then
       DBMS_OUTPUT.PUT_LINE(‘在RUNBYPARMETERS过程中出错！‘);
  end;

  四、在Oracle中对存储过程的调用
  过程调用方式一

 declare
        realsal emp.sal%type;
        realname varchar(40);
        realjob varchar(40);
  begin   //存储过程调用开始
        realsal:=1100;
        realname:=‘‘;
        realjob:=‘CLERK‘;
        runbyparmeters(realsal,realname,realjob);     －－必须按顺序
        DBMS_OUTPUT.PUT_LINE(REALNAME||‘   ‘||REALJOB);
  END;  //过程调用结束
 

过程调用方式二

declare
       realsal emp.sal%type;
      realname varchar(40);
       realjob varchar(40);
 begin    //过程调用开始
       realsal:=1100;
     realname:=‘‘;
      realjob:=‘CLERK‘;
      runbyparmeters(sname=>realname,isal=>realsal,sjob=>realjob);
 －－指定值对应变量顺序可变
      DBMS_OUTPUT.PUT_LINE(REALNAME||‘   ‘||REALJOB);
 END;  //过程调用结束

至此，有关ORACLE的基本存储过程以及对Oracle存储过程的调用方式介绍完毕。
