Influxdb select time

To use with InfluxDB, cast the return value to a timestamp. The following example uses the sample data set provided in Get started with InfluxDB tutorial. To use with InfluxDB, cast the return value influxdb select time a string.

This Product. Time Series Database:Time Syntax. By default, the start time of the time range is specified by the The end time of the time range is the time that is returned by the now function. If you do not specify this element, the default value.

Influxdb select time

I am using influxdb and in the select query I read time and newTs as db field represents epoch in ns as below. So how can I use variable in the where clause, I have added newTs as integer variable in the database, even I tried newTs::integer in the select query but it fails. How to solve this problem? Can any expert please guide me on this, it would be of great help? I searched a lot on Google and Influx Documentation but failed to find this precise information. There may be a workaround, but I suspect your best bet would be trying to run the query in Flux instead. Either way, since this is purely an Influx and not a Grafana question, the Influx forum may be a better place to find a solution. Thanks svetb for reply. I am running query under grafana itself. So what are the ways by which I can workaround this problem. Any reason for this kind of restriction? Also one more question I had, can I create new variable say TimeCopy from Time and use this as integer for comparison with my variable? I tried this as well, but TimeCopy and Time field both can not co-exists in influx, afaik.

If you do not specify this element, the default value I have the same problem as jianwu. You switched accounts on another tab or window.

Hello Nibeckj , Welcome. You can create variables for those times and use the flux date package. Anaisdg : Can you please give another hint how to combine create-variable and the date-packages? Nibeckj : Did you find a solution to your problem. For Nibeckj original use case, the query would look something like:.

For more information, see error about mixing aggregate and non-aggregate queries. This clause supports several formats for specifying a measurement s :. While not always necessary, we recommend that you double quote identifiers. Note: InfluxQL quoting guidelines differ from line protocol quoting guidelines. Please review the rules for single and double-quoting in queries.

Nibeckj : Did you find a solution to your problem. For Nibeckj original use case, the query would look something like:. Thanks a lot for the quick help! Such an easy solution. Just for notice: For my final solution I combined it with a union so that I can get a result set which spans over midnight the day before until the current day.

The first preset minute time boundary begins at and ends just before I think I have the exact same problem as feliksik. Are you able to do that? Thank you for being part of our community! I am running query under grafana itself. Specify a time range with RFC date-time strings. Separate multiple measurements with a comma ,. Flux is going into maintenance mode. Copy link. InfluxQL is designed for working with time series data and includes features specifically for working with time. Note that the results above are partial as the dataset is large. We welcome and encourage your feedback and bug reports for InfluxDB and this documentation. The FROM clause specifies a single measurement.

A time series database TSDB is specifically made for data that can be evaluated as a "time-series," which includes sensor outputs, market trends, CPU utilization, and application performance metrics. Most popular types of databases both SQL and NoSQL are not optimized for handling large-scale scans, or summarization or aggregation of time-series data. Time-series databases have built-in functionality to work with aggregation, down-sampling, data lifecycle management and summarization.

Flux is going into maintenance mode and will not be supported in InfluxDB 3. If N2 is greater than the number of series in a measurement, InfluxDB returns all series from that measurement. Is this usecase possible some other way? Anaisdg May 26, , pm 2. Basic arithmetic operations All timestamp formats support the basic arithmetic operations. Two raw points 8. Yes No Thank you for your feedback! Example 1: fill Example 2: fill linear Example 3: fill none Example 4: fill null Example 5: fill previous. Clear story. By default, InfluxDB assumes that all epoch timestamps are in nanoseconds. InfluxQL supports multiple nested subqueries per main query. The query returns data with timestamps that occur between August 19, at and August 19, at This can cause InfluxDB to overwrite points that were previously differentiated by a tag value. Note that fill previous fills the result for TZ with the result from TZ.
