        update subasta set FK_idofertaganadora=ID_OFERTA.CURRVAL where pk_idsubasta=subast;
    END IF;
END ADD_OFERTA;

我的问题是在第二个Exeption Oracle中显示：

错误（19,5）：PLS-00103：遇到以下其中一项时遇到符号“EXCEPTION”:(如果循环mod为空pragma提升返回选择更新，则在开始情况下声明结束退出时使用<< continue close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe purge

错误（28,15）：PLS-00103：遇到以下其中一项时遇到符号“end-of-file”：end not pragma final instantiable order overriding static member constructor map

    您不能在同一个块中多次使用相同的异常 . AFAIK，EXCEPTION语句就像整个块的Error-Catcher一样，所以你想把你的proc分成两个不同的块，就像这样（我想，我自己从未这样做过）：

    CREATE OR REPLACE PROCEDURE ADD_OFERTA(valorO IN NUMBER, ali IN VARCHAR,subast IN NUMBER) AS    

    fech DATE;  
    cedCompr INTEGER;
    reqpor INTEGER;
    reqmin INTEGER;
    inicial NUMBER;
    mejor NUMBER;
    tmp INTEGER;
    prueba NUMBER;                      
BEGIN    
fech := SYSDATE;

  BEGIN
    select porcentaje into reqpor from requisito;
    select incremento into reqmin from requisito;
    select precioInicial INTO inicial FROM subasta Where fk_idofertaganadora is null and PK_idSubasta=subast;

    EXCEPTION
        WHEN NO_DATA_FOUND then
            INICIAL:=0;
  END

  BEGIN
    SELECT pk_idParticipante into cedCompr from PARTICIPANTE p where p.FK_ALIASUSUARIO = ali;     

    select o.valorOferta into mejor from subasta s inner join oferta o on(s.fk_idofertaganadora=o.pk_idoferta) where s.pk_idsubasta=subast; 

    EXCEPTION     
        WHEN NO_DATA_FOUND THEN-- ERROR here
            INICIAL:=0;
  END

  select greatest((inicial),(mejor+reqmin),(mejor*(reqpor/100 + 1))) into prueba from dual;

  IF (valorO>=prueba) THEN

        INSERT INTO OFERTA(PK_idOferta,fecha,valoroferta,fk_idcomprador,fk_idsubasta) VALUES(ID_OFERTA.NEXTVAL,fech,valorO,cedCompr,subast);
        update subasta set FK_idofertaganadora=ID_OFERTA.CURRVAL where pk_idsubasta=subast;
  END IF;
END ADD_OFERTA;
