无详细内容 Oracle 游标 -- 时间函数实例:select sysdate,add_months(sysdate,12) from dual; --加1年select sysdate,add_months(sysdate,1) from dual; --加1月select sysdate,to_char(sysdate+7,'yyyy-mm-dd HH24:MI:SS') from dual; --加1星期select sysda

Oracle 游标
-- 时间函数实例:

select sysdate,add_months(sysdate,12) from dual;        --加1年
select sysdate,add_months(sysdate,1) from dual;        --加1月
select sysdate,to_char(sysdate+7,'yyyy-mm-dd HH24:MI:SS') from dual;   --加1星期
select sysdate,to_char(sysdate+1,'yyyy-mm-dd HH24:MI:SS') from dual;   --加1天
select sysdate,to_char(sysdate+1/24,'yyyy-mm-dd HH24:MI:SS') from dual;  --加1小时
select sysdate,to_char(sysdate+1/24/60,'yyyy-mm-dd HH24:MI:SS') from dual;  --加1分钟
select sysdate,to_char(sysdate+1/24/60/60,'yyyy-mm-dd HH24:MI:SS') from dual;  --加1秒

-- 游标循环实例:

-- 查询出多条数据,但是需要一一循环出来,类似java里的遍历

declare
v_yhzh varchar2(20); --定义变量用户号
v_phone varchar2(11); --手机号
CURSOR cur_1 IS select dy.user_sid,dy.user_mobile  from dx.dy_order dy; --将结果存入cur_1
begin
  open cur_1; --打开游标
  loop   --循环
    fetch cur_1 into v_yhzh,v_phone; --依次将游标的值给v_yhzh
    exit when cur_1%notfound; --循环的条件
    dbms_output.put_line(v_yhzh||'---'||v_phone); --打印输出
    end loop; --循环结束 内陆运输
    close cur_1;  --关闭游标
end; --结束
