oracle pl/sql 中创建序列号

模式：

create sequence 序列号名

minvalue 最小值
maxvalue 最大值

start with 目前值
increment by 步长

nocache;

举例：

-- Create sequence
create sequence SEQ_ALLACTIVESEARCHINFO
minvalue 1
maxvalue 999999999999999999999999999
start with 15
increment by 1
nocache;

应用：

select seq_allactivesearchinfo.nextval into l_searchid from dual;

alter sequence seq_allactivesearchinfo increment by 200;//200为步长

注意：maxvalue 999999999999999999999999999中最长可以有40个9
