QUESTION
I am using an historian to search for certain values of a specific tag. The historian has certain rules, such as, I cannot create or drop tables, queries need tagnames etc.
I want to search a TagName 'Tank1' for example and return its DateTime and Value results, then search further Tags using these results to match those tags that have the same Values at that DateTime.
I search 'Tank1' between a given date and time and receive 4 results as below
2021-11-02 08:00:54.9870000 1 2021-11-02 10:22:27.9850000 1 2021-11-02 11:47:31.3360000 2 2021-11-02 23:11:57.8120000 2So, I need to search four other Tags and return results that match the dateTime and value.
The below code is what I have produced (I should now tell you that I am a virtual novice)
...ANSWER
Answered 2021-Dec-10 at 16:56If I'm understanding correctly, you are hoping your int
and datetime
variables (@AT1DateTime and @AT1Value) will hold more than one value returned by the first query. That won't work (as you indicated, they will hold only one value).
From the code provided, it's not clear that you need to store those values in a variable at all. I think you are probably looking for something like:

I need to assign 275 variables with the Double type. Is there a way I can paste word Double on all 275 lines at once? I have been pasting Double on each line and its tiring.(I also have to add the underscores to replace spaces in the variable identifiers. If anyone knows a shortcut for that let me know.)

Answered 2021-Jun-09 at 20:23You could use a tool like Notepad++ to make the changes you need.
I was able to convert the list you supplied by using "CTRL+H" to open the replace dialog, using regular expression mode, and replacing "\d+" with "Double":

QUESTION
Trying to determine a PASS/FAIL result from dataset where the expected number of FLAG values in a column is predetermined, and another column of the same rows match specific text.
If the number of values found in the Descript column equals the predetermined number AND the PValue of each of those rows match the text 'PASS' then the result is text 'PASS'.
If the number of values found does not equal the predetermined number, the result is text 'FAIL' regardless of the PValue content.
If number of values found equal the predetermined number but one or more of the PValue entries does not equal 'PASS' then the result text is 'FAIL'.
Example input data with expected number of FLAG rows = 3:
Descript PValue uniqueID Last year 1 FLAG PASS 2 Master product 3 FLAG PASS 4 FLb PASS 5 Prime Minister 6 Laurie Quiz 7 FLAG PASS 8 Hugh Who 9expected result of above data:
count PASSelse the output:
count FAILThis is my query so far:
...ANSWER
Answered 2021-Apr-17 at 22:51If the number of values found in the Descript column equals the predetermined number AND the PValue of each of those rows match the text 'PASS' then the result is text 'PASS'.
If I understand correctly, you only care about FLAG
rows. And you want to know if all flag rows are 'PASS'
and have the expected number. If so, this is conditional logic on aggregate amounts:
QUESTION
I have a historian system in SQL Server which saves certain tag values in a table.
Each month, the system creates a table (partition table) for this historical data as per the below tables.
For example, this table for the month of Feb2021 ([ sqlt_data_1_2021_02 ]
):
There’s another table that owns the partition table's name along with the start and end date for each historical table:
I need to get the data for the historized values in [sqlt_data_x_x_x] based on the start/end date. For example: start Date: 10th of Dec 2020 EndDate : 10th of Feb2021
.
This means the query should first look in the required partition table which, in this case. is [ sqlt_data_1_2021_02], [ sqlt_data_1_2021_01], [ sqlt_data_1_2020_12]
.
Then query will retrieve the date from these three tables and UNION ALL
for the results.
How can I do this dynamically, since the start & end dates are variable?
I added more clarification about the requirement
--First Query
...ANSWER
Answered 2021-Feb-18 at 11:12One option would be to create a dynamic query that picks up all the tables. But it can be error-prone and difficult to debug.
Instead, I think your best bet here is to use dynamic SQL to create a view that contains all the necessary tables aggregated together. We can use a SQL Server Agent job to periodically maintain the view, with this code:
QUESTION
The Riddler service does not have explicit documentation at the package level and is not addressed in the Routerlicious service.
There is some code level documentation
Riddler manages the tenants and then gives them to server for Alfred and Historian.
How should I be thinking about Riddler? Especially in relation to Alfred and Historian.
...ANSWER
Answered 2021-Mar-07 at 12:20Riddler manages Tenants. In Routerlicious a tenant is a secret key & unique identifier pair. A tenant is usually a company or user group. The secret key is used to sign JWT tokens and the unique identifier identifies the tenant.
For example, during a hackathon we would give each hackathon team a different tenant. If we had a production service, we would give each company a different tenant.
Riddler lets you create and manage these tenants in Routerlicious.
In contrast, Historian and Alfred consume this tenant information. Historian and Alfred are not responsible for creating new tenants (new secret key, unique identifier pairs).

I'm currently trying to solve a little problem.
I have the following code. I try to filter and re-render the fetched movielist based on the chosen genre.
So far i am able to cast the selected option to an object in my js-script but i don't know where to go from here. The genre values in my observable array is an array of its own since one movie can have multiple genres.
Here's my script so far:
...ANSWER
Answered 2020-Dec-12 at 01:27You could add a computed observable filteredMoviesList
which would go through each of the filters you describe and filter for the selected genre. Then in your html you would just bind your foreach binding to that instead of moviesList
. Here is a simple example:
