oracle中可以不用selectKey而直接把Sequences生成ID写在SQL语中吗?

<insert id="insertProduct-ORACLE" parameterClass="product">   
    <selectKey resultClass="int" type="pre" keyProperty="id" >   
        SELECT STOCKIDSEQUENCE.NEXTVAL AS VALUE FROM DUAL   
    </selectKey>   
    insert into PRODUCT (PRD_ID,PRD_DESCRIPTION) values (#id#,#description#)   
</insert> 

<insert id="insertProduct-ORACLE" parameterClass="product">   
    insert into PRODUCT (PRD_ID,PRD_DESCRIPTION) values (STOCKIDSEQUENCE.NEXTVAL,#description#)   
</insert>
