Thank you for your help! P. Is curious to mention that this more simple approach was mentioned in the thread linked in the opening post, but was discarded. Finally, if the last measurement (from the first query) is before T2, do this: and InfluxDB would go across all shards to find that value (e. Return the oldest five points from one series without ORDER BY time DESC: 一 了解InfluxDB的必要性 时序数据库主要存放的数据 Time series data is a series of data points each associated with a specific time. LIMIT分页，LIMIT后面的数字是查询显示多少条，OFFSET后面数字代表偏移量（从0开始代表第一条），如limit 10 offset 10意思为 I checked the previous open issues and it looked like this has been resolved. Because you called group() you removed that default grouping, but that doesn't force a re-sorting, so you 在InfluxDB中查询时，默认返回的数据时按照time升序排序的。而通过ORDER BY time DESC子句，可以将查询结果进行倒序排序。 语法： SELECT_clause [INTO_clause] FROM_clause [WHERE_clause] [GROUP_BY_clause] ORDER BY time DESC. This would be an exception to allow some switching between subquery order by time that was restricted in #8754. To find support, use 如果没有包含order by子句，默认行为是按时间升序排序数据：order by time asc。; 如果查询包含where和group by子句，则order by子句必须在这些子句之后。; 排序顺序. The time issue is solved. Maybe it was just lost Use the ORDER BY clause to sort results by specified columns and order. 感谢您成为我们社区的一员！我们欢迎并鼓励您为 InfluxDB 和本文档提供反馈和错误报 Since sorting is only possible for the timestamp and tags, you might think about using a tag instead of a field for value2.

Try It Free. Return the oldest five points from one series without ORDER BY time DESC: 输出：total,ljnsxhtotal,SBXLH,time 3、聚合函数 （1）influxdb中使用聚合函数与mysql存在差异，influxdb中的聚合函数只能使用基础的功能，如count(1)不可使用，可使用count(字段) 返回字段有数据的总条数，不能使用count(time) （2）聚合函数内加条件 如：count(字段=0 or NULL)，sum(字段+字段)，sum(CASE when online = 1 then 1 I am using 0. ORDER BY time DESC reverses that order such that InfluxDB returns the points with the most recent SELECT "water_level", "time" FROM "h2o_feet" WHERE "location" = 'coyote_creek' ORDER BY time DESC. The setup works fine for time series plots, there also the measurement name is displayed. Use the ORDER BY clause to sort data.

Using a simple test script against a InfluxDB 0. By default, InfluxDB returns results in ascending time order; the first point returned has the oldest timestamp and the last point returned has the most recent timestamp. InfluxDB Clustered. The LIMIT 2 clause limits the number of points returned to two. GROUP BY * [, time (time_interval)] [ORDER_BY_clause] [LIMIT_clause] [OFFSET_clause] SLIMIT_clause SOFFSET < N > N specifies the number of series to paginate. 默认情况下，InfluxDB按时间升序返回结果；返回的第一个点具有最早的时间戳，返回的最后一个点具有最新的时间戳。ORDER BY time DESC反转该顺序，以便InfluxDB首先返回带有最新时间戳的点。 在InfluxDB中查询时，默认返回的数据时按照time升序排序的。而通过ORDER BY time DESC子句，可以将查询结果进行倒序排序。 语法： SELECT_clause [INTO_clause] FROM_clause [WHERE_clause] [GROUP_BY_clause] ORDER BY time DESC 示例 ： Use the ORDER BY clause to sort results by specified columns and order. Full details are in the InfluxDB changelog, but here are some of the highlights. ORDER BY time DESC reverses that order such that InfluxDB returns the points with the most recent timestamps first. Or better in my opinion would be group by time as inverted order, so that I would the 7 days range would start from today back, but order by does not the trick.
