Oracle 序列的创建和使用
|
创建序列
create sequence seq_a minvalue 1000 maxvalue 99999999 start with 1000 increment by 1 nocache;
查询序列
select seq_a.nextval from dual;
drop sequence seq_a
为每张表生成对应的序列
--创建存储过程
create or replace procedure p_createseq(tablename in varchar2)
is
strsql varchar2(500);
begin
strsql:='create sequence seq_'||tablename||' minvalue 1000 maxvalue 99999999 start with 1000 increment by 1 nocache';
execute immediate strsql;
end p_createseq;
/
--创建序列
exec p_createseq('t_power');
exec p_createseq('t_roler');
exec p_createseq('t_roler_power');
