Influxdb string contains For some reason it only matches rows with what I assume is the last value in the array. substr: Substring to use to replace part of the specified string (str). 1, moving from JSON to influxDB line protocol. Is there any way we can get those rows where column contains specific string? For e. Here’s what I’ve done. The line protocol is a text based format for writing points to InfluxDB. Otherwise it How to return specific rows from InfluxDB measurement when the column contains a string value. cutset (Required) Leading and trailing characters to remove from the string. You should use this type if you expect the string to be re-used over and over, such as is common with identifiers. Select Where field contains string. _value type Returned value; string: Integer equivalent of the numeric string: bool: 1 (true) or 0 (false) duration: Number of nanoseconds in the specified duration set() assigns a static column value to each row in the input tables. I’ve also log data in InfluxDB, therefore fields of type string. Examples Split a string into an array of substrings Since you are trying to group by the prefix of the column names, you could try following: create a new column based on the prefix; group by the new column I'm using InfluxDB with Grafana, and I have a measurement called items with some tags and a field called itemType. 4 Platform: Windows Code sample to reproduce problem # You can generate a Token from the "Tokens Tab" in the UI token = token org = "my-org" bucket = "bucket" with InfluxDBClient.

Writes data into InfluxDB. I want to How to return specific rows from InfluxDB measurement when In the documentation for InfluxDB v1 I found the maximum size of strings to be 64 KB. NChar. 2 geo. pos: Start position of the substring replacement (substr). stContains() returns boolean indicating whether the defined region contains a specified GIS geometry. Related questions. array. The format of the line consists of three parts: [key] [fields] [timestamp] If the string contains a double-quote or backslashes, influxDB. x, 1. One output table is produced for each input table. . STRING. The problem is that I collect all sensor data (7 values) as a string. I need to filter for rows where itemType is a certain string. 0. Influxdb should support CRLF! – The null type represents a missing or unknown value. 5. toUpper vs toTitle. 2 We recently started to switch to InfluxDB 1. For example return a 0 when filtration_status = OFF and a 1 when filtration_status = ON in the example above. I have a table in InfluxDB which, for optimization, contains a field that can either come only as it would be for example "FR204" or it can come in a string concatenated by commas as would be the case with "FR204, FR301". 1 on Linux I’m trying to extract values from a column into an array which I can use in a contains() function but I keep tripping on something.

Function type signature (v: string) => int. Use the bool() function to convert the following basic types to booleans:. In this case, since A is earlier in the alphabet than I, Apache DataFusion sorts first, and we know the strings are not equal. Values can be any data type. Function type signature (arr: [string], v: string) => string String length is determined by the number of UTF code points a string contains. _measurement, I have some sales data in InfluxDB, basically every 10 seconds I record the total number of sales from SQL, then break that down into sales of different items in the fields. In either case, only the branch taken is evaluated and only side effects associated this branch will occur. Each line defines a single point. Keys (also known as labels) are strings. If the result is true, the expression that follows the then keyword is evaluated and returned. Using Fiddler for testing purposes caused brought up new errors. What you expected to happen: I see data every time I fresh the dashboard or select a different value in dropd consider having the following line protocol data: my_measurement,foo="Some" bar="Thing",baz=123 where foo is a tag and bar and baz are fields, I need to get, say, a string "Some|Thing" out of InfluxDB OSS v2 using the Flux language. replace() replaces the first i non-overlapping instances of a substring with a specified replacement.
