建立自增序列：
create sequence SEQ_INCREMENT_LOG

increment by 1 

start with 1 
minvalue 1 
maxvalue 999999999;

查詢oracle自增序列：

select SEQUENCE_OWNER,SEQUENCE_NAME from dba_sequences where sequence_owner='PPNIE';

xml片段：

  <insert id="insert" parameterType="cn.com.soft.domain.IncrementLog">

      select SEQ_INCREMENT_LOG.NEXTVAL as id from dual
    </selectKey>
