Note: The SELECT statement requires a SELECT clause and a FROM clause. Tag “asnum” (AS number) is the main contributor to series cardinality. This is working fine the only issue is, that also the INTO示例sql 示例一在InfluxDB中，是无法直接重命名一个库的，所以一个通常的做法是，像如上的sql那样，把一个库的所有数据全部复制到另一库中去。其中 GROUP BY * 文章浏览阅读1. This can be done with this statement: select * into testtable2 from 通过INTO子句，可以将用户的查询结果插入到用户指定的measurement中。语法. For longer periods I’d like to create another “longterm” measurement with the Hm, that could work. When I query my influxdb like this, I get the desired results. Can be a field key, constant, regular expression, wildcard (*), or function expression and any combination of arithmetic operators. It requires one or more field expressions and optional tag expressions. I have a time series which very seldom writes new entries to the db. I spotted the trouble when listing the tag and fields keys as show tag keys show field keys Deleting all records does not remove the keys from these lists and the Looks like SELECT * FROM ketag. . Fields are not indexed, and can be selected as columns in the result. Even if I group by any other time interval, it returns a 5 minute interval. If the SELECT clause contains only tag keys, an empty string is returned. com 1 I’m using a Continuous Query to downsample some information like Hello all, i searched hard for the last few days for a solution to my problem. Stack Overflow Questions Help Chat Products Teams What are some good rules and examples of how to choose between storing data in fields vs. A free tier of InfluxDB 3 Enterprise will also be available for at-home, non-commercial use for hobbyists to get the full historical time series database set of capabilities. Is it possible to include multiple queries in the where clause . I would like to select a range of them, kind of 200 of them to visualizing them. SELECT "old_field_key" AS "new_field_key" INTO new_db. In InfluxDB 3 Core, the primary key for a row is the combination of the point’s timestamp and tag set—the collection of tag keys and tag values on the point. For example, if you have accidentally stored a measurement with a value of -1 in a series of positive Expensive approaches Without timerange # Copy all valid data to a temperature measurement with a sensor tag and a value field of type float state measurement with a sensor tag and a value field of type string It looks like the SELECT * INTO command only copied the temperature measurement to the new database. select * from students where rollNumber='1' limit 10 students is the measurement and rollNumber 通过上篇博客，我们已经简单认识了InfluxDB了，其实在实际使用中，我们最常用的就是查询了，这篇博客就详细了解下InfluxDB的查询操作一、常用查询 1、从单个measurement查询所有的field和tag SELECT * FROM 升级 InfluxDB 扩展您的集群管理环境变量绕过您的身份提供者指南 API 兼容性 v2 API v1 API 迁移数据从 TSM 迁移到集群从 1. a_year. Flux documentation says that filter() function is the equivalent of both SELECT and WHERE clauses, but all . tags when designing InfluxDB bool, or any other valid field type) and are meant for data. For example: select * into B from A all tags will be converted to fields. 145224194 and 2262-04-11T23:47:16. field_expression: Expression to identify one or more fields to return in query results. InfluxDB 3 Enterprise is a commercial version that builds on Core’s foundation, adding historical query Hi every body, i am a newbie in influxql, i’ll try to select tag between select and from clause but it doesnt work. How can you query data without SELECT clause? When querying over influxdbs HTTP API it expects one of the following keywords first: SELECT, DELETE, SHOW, CREATE, DROP, EXPLAIN, GRANT, REVOKE, ALTER, SET, KILL. There is no way to select only the fields by wildcard. filter() performs operations similar to the SELECT statement and the WHERE clause in InfluxQL and other SQL-like query languages. 0 ? We did found the solution but for v1. All of the old statuses I believe I have discovered the reason: two keys from the tags made by mistake their way into the fields. old_measurement GROUP BY "old_tag I have a high cardinality measurement with traffic data stored every 5 minutes: fieldKeys: bytes,packets (both integer) and tagKeys: device, asnum. However, in SQL, both: SELECT DISTINCT mytag FROM mytable; SELECT mytag FROM mytable GROUP BY mytag; fail to I am visualizing a data base in Grafana produced for InfluxDb. Selector functions return one or more rows with the selected values from each InfluxQL group. A wide variety of areas are measured, such as the fill level of a waste garbage can or the meter InfluxDB 3 Core, is our new open source product. single_measurements GROUP BY time(15s), * from CLI manually to see whether it Primary keys In time series data, the primary key for a row of data is typically a combination of timestamp and other attributes that uniquely identify each data point. It took a bit of thinking to understand my own question, which perhaps lacked some context! What I’m trying to do is detect whether there have been any changes to “version” for a particular “thing” (in real life Hi everyone, We are currently facing the challenge of storing various sensor data in an InfluxDB and do not know exactly how to name the measurements, tags and fields optimally. 插入到指定measurement中。此时使用的是当前库、使用默认 Be sure to use GROUP BY to identify the tags. If you want all fields, but not all tags, you have to explicitly name each field. My points have the field ping_to_google. measurementTagValues( bucket: "XYZ", measurement: "ABC", tag: "test&quo Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers FAQ about SELECT statements How do I query tag keys by using a SELECT clause?

Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand I'm trying to discern if it is possible to query InfluxDB to have an exact match on tags without having to first query InfluxDB for the TAG KEYS to generate my query. 8 and below. I could not find an operator similar to the IN operator in SQL. Is it possible to send multiple values in a single tag in influxdb using the influxdb line protocol? Something like this application-metric, application=test-app,API=get,put cpu=15 1465839830100400200 Essentially measurement and timestamp are the same but SELECT top(“iops”, 2) FROM “lun” GROUP by “name” returns a “top” value for every tag key based on a 5 minute interval. to() to write pivoted data to InfluxDB. x 迁移到集群参考 CLIs influxctl influxctl auth Influxdb 0. Each selector function below covers syntax, including parameters to pass to the function, and examples of how to use the function. com 1 1531851271263690187 demo2 example. The filter() function filter() has an fn parameter that expects a predicate function, an anonymous function comprised of one or more predicate expressions. select * into B from A group by T and T will be a tag in B, I am trying to fetch the tag values for a given measurement. This means we need to add at least one FIELD to the query. If I use the Insert command I will have to type all the field sets and tag sets individually. It is a recent-data engine for time series and event data. The SELECT clause InfluxDB requires a measurement name. 9 documentation gives an example of preserving all tags on a Continuous Query (CQ) by simply doing GROUP BY time(<some interval>), * Is there a way to preserve a subset of tags th 1. Using this method, you have control over which columns are written as fields and which as tags: Use experimental. `influxdb`作为时序库，与时间有很大的关系，`measurement`相当于一个时间轴，`point`就是 I’m creating a measurement named “master_version” that consist of tags (app_version & status) and field (version_code) using a client for javascript (influx - npm). 854775806Z UTC. The state Hello, Is there any way to convert fields to tags on existing measurement with many points in influxDB v2. In InfluxQL, I used: SHOW TAG VALUES FROM mytable WITH KEY = mytag; This query runs in 324ms. I have a solution that I can use python and query the data points and manipulate the data then insert it back. To limit the result 数据库也叫database，只是表名变了，measurement测量值的含义更能体现influxdb的特点，存储的数据是在时间的刻度上统计测量的结果，并不是一些冷冰冰的数值。正因为如此，数据记录的概念也有所不同，influxdb的一行记录称之为point，一个点。point由3部分组成time+fields+tags。 Note: InfluxDB does not support using OR in the WHERE clause to specify multiple time ranges. This is caused by 通过上篇博客，我们已经简单认识了InfluxDB了，其实在实际使用中，我们最常用的就是查询了，这篇博客就详细了解下InfluxDB的查询操作一、常用查询 1、从单个measurement查询所有的field和tag SELECT * FROM measurement_name where tag='serverA' 2、从 I have a simple InfluxDB schema called SWPFND that looks like this: time base counter prov_ticker provider rate source ticker utc_received ---- - Hi everyone, I’m migrating from InfluxQL to SQL in InfluxDB v3 Cloud and I need an efficient way to get distinct tag values. As I understand it, there are feature requests open to rename metadata, (one of which We are releasing two products as part of the alpha. To group and aggregate data into time-based groups: In your SELECT clause, apply aggregate or selector functions to queried fields. InfluxDB lets you delete points based on WHERE tag='value' conditions, but not by field value. Use the SELECT statement to query data from a particular measurement or measurements. now I don’t need the tag id, I planned to delete the id and copy all the data to a new measurement, I tried to export to CSV, but field, maybe due to the count is more than 5000K, then I happened to find the select into clause, select time value into measurementB Is there any shortform syntax in influxdb to query for membership in a list? I'm thinking of something along the lines of SELECT * FROM some_measurement WHERE some_tag IN ('a', 'b', 'c') For now I can string this together using ORed =s, but that seems very inefficient. influxdb基础（二）——influxdb基本概念 (database、measurement、fields、tags) + 简单实操 (简单insert、select)，1. I’ll play around a bit more to see if I can figure this out. We tried using below query to copy one measurement data into another but 不过也可以通过select * into newxxx from oldxxx，从旧表中查出数据导入到新表。 select * into newxxx from oldxxx，会将原表的tags当作fields复制到新表，可以在语句后面加上group by，这样就可以把tag复制过去了。 #指定所有的tags select * into newxxx from I am using the command "show tag values on with key = " it is showing me the list of tags but I want to count the entries related to that tag. InfluxDB 3 Enterprise is a commercial version that builds on Core’s foundation, adding historical query I am using an InfluxDB data source in Grafana. For example, InfluxDB returns an empty response for the following query: Timestamps For most SELECT statements, the default time range is between 1677-09-21 00:12:43. com and the tag key user where user can be raspi-2 or raspi-5. filter() performs operations similar to the SELECT statement and the WHERE clause in InfluxQL and other If you are using influxdb, one usecase could be, copy the data from a measurement ("table") to another. This SELECT clause The SELECT clause supports several formats for identifying data to query. VarRef (or something else) so that it could have knowledge of both the name of the SELECT "<field_key>","<tag_key>" - Returns a specific field and tag. It looks ok so far to keep all series for short term retention policy. downsampled_value should work. INTO子句支持如下语法，使得用户可以使用不同方式来指定要插入数据的measurement：插入到指定measurement中。此时使用的 The SELECT clause must specify at least one field when it includes a tag. But my application (grafana) expects a lot more often updated values. Input data must have the following SELECT clause The SELECT clause supports several formats for identifying data to query. The value is treated as a string instead of an integer, eventhough it is inserted as an integer in the original measurement, but I think tags are probably treated as a type of string. SELECT "<field_key>"::field,"<tag_key>"::tag Returns a specific field and tag. Is it possible to somehow convert (cast) the tag value into an Thanks for your answer. InfluxDB 3 Enterprise is a commercial version that builds on Core’s foundation, adding historical query capability, read replicas, high availability, scalability, and fine-grained security. There’s no issue with inserting and showing the data, but one day I use the influxdb CLI to insert a new point, and the “status” suddenly duplicated (into status and status_1). But this information is displayed only via the table I am trying to write a where clause on InfluxDB where the points are filtered via their key values. I have this raw data: select * FROM "message_sent" WHERE time > now() - 1m name: message_sent time appCodename host sent ---- ----------- ---- ---- 1531851267026022790 demo example. This is a sample output of the database: > select * from networks SELECT clause The SELECT clause supports several formats for identifying data to query. The :: [field | tag] syntax I believe this would work: select "response","code" from httplog See documentation on the select statement for field key and tag key. How i can write my request like : select time, code, response from httplog where time> "" code is a key and not a field : httplog,code=200,application=AAAA response=1200,size=3892 14845353453 the result is Assume you're given an InfluxDB measurement you haven't seen before and you run, SELECT * FROM measurement How can you tell which of the keys returned are tags, and which are fields? The InfluxDB shell sorts the keys alphabetically, so unlike the Line [influxdb] Select-into Usage to Rename Tag Value r***@bluesunrise. We are releasing two products as part of the alpha. This is not a big problem - you can work with that data without a problem. Use a regular expression to specify a tag with a value in the WHERE clause. InfluxDB 3 Enterprise is a commercial version that builds on Core’s foundation, adding historical query Have a look at writing pivoted data to InfluxDB, maybe that's what you need. SELECT field INTO measurement_tmp FROM measurement GROUP BY TAG-1, TAG-2, , TAG-n Common Errors It is possible to remove certain tags as described above without removing all of them (if you have SELECT clause The SELECT clause supports several formats for identifying data to query. SELECT语句需要一个SELECT子句和一个FROM子句。 SELECT子句 SELECT 子句支持多种指定数据的格式： But after copying this to a testtable, the tags where gone and everything was a field. The concerns I would have though is it would require a wire protocol change for the RPC because the Aux field in IteratorOptions would need to be changed from []string to []*influxql. Basically, I have a measurement with this fields: SALA: tag sector: field and I need that the field “sector” convert to tag for use it as a filter in templating. `influxdb`作为时序库，与时间有很大的关系，`measurement`相当于一个时间轴，`point`就是 I'm trying to query data based on tag values. If the SELECT clause in an INTO query contains tag keys, the query converts tags in the current measurement to fields in the destination measurement. SELECT "<field_key>","<tag_key>" - 返回特定字段和标签。当包含标签时，SELECT 子句必须至少指定一个字段 InfluxDB 3 Core 是我们的新开源产品。它是一个用于时间序列和事件数据的最新数据引擎。InfluxDB 3 Enterprise 是一个商业版本，它建立在的 We are releasing two products as part of the alpha. Field 与Tag说明在 InfluxDB 表结构中，field 和 tag 是用于存储数据的两种不同类型。Field（字段）： Field 用于存储实际的数值数据，例如温度、湿度等测量值。Field 是可变的，可以随时间的推移而改变其值。Field 的值可以进行聚合计数据查询语法 InfluxQL是一种类似SQL的查询语言，用于与InfluxDB中的数据进行交互。以下部分详细介绍了InfluxQL的SELECT语句有关查询语法。示例数据本文使用国家海洋和大气管理局（NOAA）海洋作业和服务中心的公开数据。请参阅示例数据页面下载数据，并按照以下部分中的示例查询进行跟踪。 Explore time series data using InfluxData’s SQL-like query language. So i want to copy the latest values of my db to a new database with a script which runs periodically. Use the filter() function to query data based on fields, tags, or any other column value. I have already used select into, but the field that I need to convert to tag is still a field. new_measurement FROM old_db. I am trying something like this but is not working: select * from <measurement> where "key" > '1' and "key" < 200 I can select a range of my field key-values, for example: select * from Use selector functions to assess, select, and return values in your data. We would then not include a field cast and would say that tags are not "just strings". InfluxDB 3 Enterprise is a commercial product that builds on Core’s foundation, adding high availability, read replicas, enhanced security, and data compaction for faster queries. Understand how to use the SELECT statement to query data from measurements, tags, and fields. (I am referring to FluxQL, the new query language developed by InfluxData) I didn't find a clear answer to this in the limited Flux Documentation present. i have my measurement in influxDB as given below. Please any help appreciated. Use filter() to query data based on fields, tags, or any other column value. How can I do it Use the filter() function to query data based on fields, tags, or any other column value. 9k次。前述网上关于influxdb数据库中tag和field迁移的文章比较少，虽然有，但是大部分都是有问题的，比如下面两种方式1、select tag1,tag2,field1,field2,field3 into target from origin2、select * into target from origin这两种sql并没有将tag和field 区分开，而是将tag作为filed导入进target表（measurement）中。 Ok so i tried out the following query (for demo purposes): SHOW TAG VALUES CARDINALITY ON "api_requests" FROM "requests_stats" WITH KEY = "api_path". I am wishing to sort these graphs by an aggregate numeric value, rather than the tag value That's correct. In one of my measurements I have like 1000 keys or tags or variables. Downsample data by applying interval-based aggregates A common use case when querying time series is downsampling data by applying aggregates to time-based groups. > select * from "EVENT_LIVE" name: EVENT_LIVE time 关于SELECT语句的常见疑问在SELECT 子句中，必须要有至少一个field key！如果在SELECT子句中只有一个或多个tag key，那么该查询会返回空。这是由InfluxDB底层存储数据的方式所导致的结果。示例：上面的查询结果返回为空，是因为在它的SELECT子句 I am using influx DB and issuing command, SELECT * FROM interface Below is the out put- interface time element path This works for me, but if I have a gazillion rows in a table but only 10 distinct tags, then it's going to sort a gazillion rows to run the distinct function. of how to use the function. com 2016-04-01 16:53:33 UTC Permalink I have a requirement to rename tag values for specific series. Specifically, we need to store sensors that have a unique ID and a fixed installation location. TSDB for InfluxDB® may overwrite the points that are differentiated by tag values. downsampled_value FROM ketag. Some of that functionality is provided by INTO. InfluxDB 3 Core, is our new open source product. The SELECT clause must specify at least one field when it includes a tag. Perhaps what I want can't be done, because I want to It would have to be done manually via queries. If not try running SELECT mean(*) INTO ketag. I have a repeating panel of graphs, grouped by a tag value. A SELECT clause without any fields is invalid. BUT if you want to copy it back or merge it to the original table, you will get a Hi, I’m trying to select a subset of data as shown below into a new measurement, and then calculate the mean value. SHOW TAG I can use the select into statement however that will not allow me to make changes to the datapoint. There is also no way to SELECT tags without at least one field value. s, but that seems very inefficient. Here is an example to showcase what I'm trying to accomplish,. Strictly speaking, tags are optional but most series include tags to differentiate data sources and to make querying both easy and Use filter() to query data based on fields, tags, or any other column value. Eg. only fields are available. com 1 1531851271255490598 demo example. This query yields a number 281 which is accurate. 前述网上关于influxdb数据库中tag和field迁移的文章比较少，虽然有，但是大部分都是有问题的，比如下面两种方式1、select tag1,tag2,field1,field2,field3 into target from origin2 通过INTO子句，可以将用户的查询结果插入到用户指定的measurement中。 INTO <measurement_name> .
