QUESTION
I would like to create a Highcharts line graph with temperature data from multiple sensors each posting results at different times. The data is stored in a MySQL database as id, location, temp, timestamp. Since each sensor will be generating data at unique times the x values will not line up. For this reason I am interested in supplying each Highcharts series with a x- value and y-value... something like:
...ANSWER
Answered 2021-Dec-20 at 10:44Notice that Highcharts expects to get x and y
values in the data array, not custom names as "reading_time"
or "temp"
, so you need to parse your data into the required format.

QUESTION
I have a flutter application where I retrieve data (temperature readings) from MySQL database. Since I get new data every 30 seconds, I would like my application to auto-refresh the screen so that new data will be displayed automatically each time it is updated. I use getReadingList()
to retrieve data and use it only in initState()
method. I know could call getReadingList()
every 30 seconds, but is there a more efficient built-in solution?
Here's what I have done so far:

Answered 2021-Feb-22 at 15:44You can't use datetime
and category
axis type at the same time. As a solution you can:
- Use

QUESTION
I use a NodeMCU arduino to send sensor data to MySQL database. I used this code to create my table
...ANSWER
Answered 2020-Sep-29 at 14:37change your datatype to BigINT
this should help for the next few years. till they decide to make it finaly 64 bit or even higher is necessary
When AUTO_INCREMENT hits the limit of the datatype it stops inserting with an error message like
Failed to read auto-increment value from storage engine
changing the id is always a bad idea so let it stay and auto_increment doesn't garantee a consequential number. you can always build one yourself look for row_numbw
QUESTION
I am completely new to C# and have zero background in the language. The only programming language I am an expert in is SQL.
My situation: I have a an API url from a website my company uses to monitor product levels in tanks. The API returns a json list of the tanks (location, tank id, tank size, current level, etc.). My goal is to create a windows form application with an input field. The user types the name of the location, clicks a button, and sees the information for any tanks at that location.
What I have tried:
What I have done so far: Again, I have zero knowledge of programming so do not be critical if I have done things in very unusual/inefficient ways. I have managed to create a windows form that has a button and text box. When the button is clicked, the text box is populated with all of the tank data from the API. I can't figure out how to filter the data that has been returned. My current code is below...
...ANSWER
Answered 2020-Sep-17 at 19:05In your class just change tank_size
and days_to_empty
to a double
and reading_time
to DateTime
.
Then Deserialize
into a List
QUESTION
I'm using Microsoft SQL Server 2016.
There is a database table "Raw_data", that contains the status of a machine, together with it's starting time. There are several machines and each one writes it's status to the database multiple times per minute.
To reduce the data volume I'm trying to aggregate the data into 1-Minute chunks to save it for further analysis. Due to a capacity constraint, I want to execute this transition-logic every few minutes (e.g. scheduled SQL Server Agent Job), delete the raw data and just keep the aggregated data.
To simplify the example, let's assume "Raw_data" looks something like this:
...ANSWER
Answered 2020-Aug-21 at 12:42For something like this, concatenating the keys to a single datetime isn’t as costly as it might seem. Then you can call DATEDIFF() to check for positive, negative, absolute, values for the comparison. I’ve run something similar translating instantaneous data to minute aggregates across multiple decades, and datediff really makes the difference. However, this would do much better if you simply pull the raw data and perform the calculations in a language with a good datetime library. SQL is always the answer until it isn’t.
What’s likely causing one of the problems here is the following statement:
