相关代码如下：

1. 创建sequence：

<div class=”codetitle”><a style=”CURSOR: pointer” data=”64620″ class=”copybut” id=”copybut64620″ onclick=”doCopy(‘code64620’)”> 代码如下:<div class=”codebody” id=”code64620″>
CREATE SEQUENCE SEQU_DATA_DATAINFO INCREMENT BY 1 START WITH 1 NOCYCLE NOCACHE NOORDER;

2. 创建触发器：

<div class=”codetitle”><a style=”CURSOR: pointer” data=”56334″ class=”copybut” id=”copybut56334″ onclick=”doCopy(‘code56334’)”> 代码如下:<div class=”codebody” id=”code56334″>
create or replace TRIGGER TRIG_TEST
BEFORE INSERT ON TABLE1
FOR EACH ROW
DECLARE
tmpVar NUMBER;
BEGIN
tmpVar := 0;
Select SEQU_PROC_ASSOCIATEINFO.NextVal into tmpVar from dual;
:new.procid:=tmpVar;
