oracle 序列重置

问题一：怎样重置oracle序列
oracle序列创建以后，假设想重置序列从 0 開始，逐渐递增1，能够採用例如以下存储过程：

create or replace
procedure reset_seq( p_seq_name in varchar2 )
is
    l_val number;
begin
    execute immediate
    'select ' || p_seq_name || '.nextval from dual' INTO l_val;

    execute immediate
    'alter sequence ' || p_seq_name || ' increment by -' || l_val || 
                                                          ' minvalue 0';

    execute immediate
    'select ' || p_seq_name || '.nextval from dual' INTO l_val;

    execute immediate
    'alter sequence ' || p_seq_name || ' increment by 1 minvalue 0';
end;
/

运行传入序列名称就可以：
execute reset_seq(‘test_seq’);
就可以
