我有什么

<强>1。我的域“User_Order”

CREATE TABLE `user_order` (

<强>3。我正在为每 5(秒 300)分钟间隔记录编写以下查询。
开始日期 = '2017-09-11 00:00:00'结束日期 = '2017-09-15 23:59:59'

select  FROM_UNIXTIME(floor(min(UNIX_TIMESTAMP(created_date))/300)*300)
                 as timestampDate,
        sum(quantity) as volume,sum(price*quantity)/sum(quantity) as wavg_price,
        substring_index(min(concat('created_date','_',price)),
                '_',-1) as open,
        max(price) as high,
        min(price) as low,
        substring_index(max(concat ('created_date','_',price)),
                '_',-1) as 'close'
    from  user_order
    where  created_date between '2017-09-11 00:00:00' AND '2017-09-15 23:59:59'
    group by  floor(unix_timestamp(created_date)/300)
    order by  created_date;

我想要什么

1. 输出只给出表的当前记录，即使我需要每个间隔的所有记录都有默认值或以前的记录值(打开、关闭、高、低及其时间戳)
   情况a)
   这里，'2017-09-11 00:05:00'没有记录。在这种情况下，开盘价、收盘价、最高价、最低价将被设置为 0(零)。
   案例 b)
   在这里，'2017-09-15 05:25:00'、'2017-09-15 05:30:00' 和 extra 没有记录，但它位于两个记录'2017-09-15 05 之间: 20:00' 和 2017-09-15 08:30:00。在这种情况下，'2017-09-15 05:25:00' 的 ohlc 值应该是前一个日期时间('2017-09-15 05:15:00')ohlc 值设置。

谢谢

Answer 1

要获取丢失的记录，您需要

1. 用所有需要的值创建一个额外的表
2. LEFT JOIN 从额外表到您已有的查询
3. 对将出现在输出中的 NULL 做一些处理。

如果您使用的是 MariaDB，则有一个方便的“序列”生成器。对于第 1 步。在 MySQL 中，我建议您预先构建一个表，例如，从 0 到一百万的数字，然后使用 + INTERVAL ... SECOND 从中创建 5 分钟的日期时间
