相关代码如下：
1. 创建sequence：
CREATE SEQUENCE SEQU_DATA_DATAINFO INCREMENT BY 1 START WITH 1 NOCYCLE NOCACHE NOORDER;
2. 创建触发器：
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;
EXCEPTION
WHEN OTHERS THEN
-- Consider logging the error and then re-raise
RAISE;
END;
