First off, I admit that I am not sure whether what I am trying to achieve is possible (or even logical). Still I am putting forth this query (and if nothing else, at least be told that I need to redesign my table structure / business logic).
In a table (myValueTable) I have the following records:
Item
article
from_date
to_date
myStock
1
Paper
01/04/2021
31/12/9999
100
2
Tray
12/04/2021
31/12/9999

Paper
28/04/2021
31/12/9999
150
4
Paper
06/05/2021
31/12/9999
130
As part of the underlying process, I am to find out the value (of field myStock) as on a particular date, say 30/04/2021 (assuming no inward / outward stock movement in the interim).
To that end, I have the following values:
varRefDate = 30/04/2021
varArticle = "Paper"
And my query goes something like this:
get_value = myValueTable.objects.filter(from_date__lte=varRefDate, to_date__gte=varRefDate).get(article=varArticle).myStock
which should translate to:
get_value = SELECT myStock FROM myValueTable WHERE varRefDate BETWEEN from_date AND to_date
But with this I am coming up with more than one result (actually THREE!).
How do I restrict the query result to get ONLY the 3rd instance i.e. the one with value "150" (for article = "paper")?
NOTE: The upper limit of date range (to_date) is being kept constant at 31/12/9999.
Edit
Solved it. In a round about manner. Instead of .get, resorted to generating values_list with fields from_date and myStock. Using the count of objects returned; appended a list with date difference between from_date and the ref date (which is 30/04/2021) and the value of field myStock, sorted (ascending) the generated list. The first tuple in the sorted list will have the least date difference and the corresponding myStock value and that will be the value I am searching for. Tested and works.
I've been trying to do a report about the quantity of breakdonws of products in our company. The problem is that the QUERY function is operating as normal, but the sorting order is well - a bit strange.
The data I'm trying to sort are as follows (quantities are blacked out since I cannot share those informations):
Raw data
First column - name of the product, second, it's EAN code, third, breakdown rate for last year, last column - average breakdown rate. "b/d" means "brak danych" or no data.
What I want to achieve is to get the end table with values sorted by average breakdown rate.
My query is as follows:
=query(Robocze!A2:D;"select A where A is not null and NOT D contains 'b/d' order by D desc")
Final result
As You can see, we have descending order, but there are strange artifacts - like the 33.33% after 4,00% and before 3,92%.
Why is that!?
try:
=INDEX(LAMBDA(x; SORT(x; INDEX(x;; 4)*1; 0))
(QUERY(Robocze!A2:D; "where A is not null and NOT D contains 'b/d'"; 0));; 4)
I've been working on a spreadsheet with over 100 rows, and found a hacky way to incorporate a "hide" checkbox that will hide any row where column C matches a specific value (building type), specified beside the box. To do this, I first created a function like this: =FILTER(Data!A1, OR(Data!$C1<>$O$2, $P$2)) and dragged that across every row and column in a seperate sheet. This reads as, "Display current cell if the corresponding column C in that row in Data does not match the building type, or if the the checkbox is checked. This way, the whole row is hidden when the building type matches, and the box is unchecked. A1 adjusted to each row individually, $C1 referenced the building's type, $O$2 referenced the targeted type to potentially hide, and $P$2 was the checkbox.
Problem #1: This created a lot of formulas in hundreds of cells, and when the building type was not found, it displayed #N/A across the entire row. A Filter View was able to hide these values, but it was inconvenient to have to reset the values every time I wanted to hide or unhide another building type.
My Attempt to Fix: I used a filter function once again to recreate the entire sheet from one cell, hiding the appropriate rows, using this: =FILTER(Data!A2:J191, ARRAYFORMULA((Data!$C2:C191<>$O$2)+(Data!D2:D191*$P$2)) This is the hacky part. I multiplied the checkbox's "true" by an array arbitrary positive numerical values in the D column to "OR" it with each building type value to achieve the same goal as before, but for EVERY cell.
Problem #2 arose: When I get my beautiful sheet, I can not sort it via a filter view, or it will throw an error and display nothing. I'm resorting to sorting the original tab, but intend to have it be ignored entirely. So how do I combine these two, Filter View, and Filter Function, to create a nice spreadsheet where I can SORT AND HIDE rows?
Bonus Problem #3: To add more buttons, my formula is this: =FILTER(Data!A1:J191, ARRAYFORMULA((Data!$C1:C191<>$O$2)+(Data!D2:D192*$P$2)), ARRAYFORMULA((Data!$C1:C191<>$O$3)+(Data!D2:D192*$P$3)), ARRAYFORMULA((Data!$C1:C191<>$O$4)+(Data!D2:D192*$P$4)), ARRAYFORMULA((Data!$C1:C191<>$O$5)+(Data!D2:D192*$P$5)), ARRAYFORMULA((Data!$C1:C191<>$O$6)+(Data!D2:D192*$P$6)), ARRAYFORMULA((Data!$C1:C191<>$O$7)+(Data!D2:D192*$P$7)), ARRAYFORMULA((Data!$C1:C191<>$O$8)+(Data!D2:D192*$P$8)), ARRAYFORMULA((Data!$C1:C191<>$O$9)+(Data!D2:D192*$P$9))) This is ugly, and very slow to load. Is there a way to create a function range to handle the same checks on multiple rows, and crunch it into a single formula?
Here is another monstrosity (this one has less repetition) for you:
=QUERY(
{IGNORE!A2:J, IGNORE!P2:P},
"SELECT * "
& "WHERE Col3 is not null "
& IF(COUNTIF(P2:P9, False) = 0, "", "AND NOT Col3 MATCHES '^" & JOIN("$|^", IFNA(FILTER(O2:O9, P2:P9 = False))) & "$' ")
& IF(COUNTIF(A2:K2, ">0") = 0, "", "ORDER BY Col" & JOIN(", Col", IFNA(FILTER(COLUMN(A2:K2) & IF(COLUMN(A2:K2) = 1, "", " DESC"), A2:K2)))),
0
)
Your checkboxes should remain. The second row can have just True/False values, no need for column number (a simple change will be needed COUNTIF(A2:K2, ">0") -> COUNTIF(A2:K2, True)). Also consequent sort works now (but only in the actual order of columns: if checked 1, 3, 4 then it will be sorted first by 1, then by 2, then by 4). You could place another config table on the right about sorting, where you would select all the columns you wish to sort by, their mutual order, and desc/asc for them.
Edit: added IFNA so FILTER won't return an error, changed multiple ANDS to MATCHES and simple regexes.
Use first two digits of Column to give a name to a new column.
I have a list of companies and their NAICS ID. I would like to filter these into a pie chart but I don't want the 90000 different names (just the general ex. Agriculture or Mining). I want to utilize the first two digits in for the column to identify its general name. I am trying to use the DAX expression Switch to get this started. Is there a filter to do this within PowerBI?
I haven't started yet since I am not sure if this is possible.
You could simply create a calculated column based off of the original NAICS code using the following:
FirstTwoDigitsOfNAICS :=
SWITCH (
TRUE (),
LEFT ( 'Table'[NAICSCode] ) = x, "Something",
LEFT ( 'Table'[NAICSCode] ) = y, "Something Else"
)
This DAX will simply pull the first two characters from the entire code.
I have a clickhouse table that has one Array(UInt16) column. I want to be able to filter results from this table to only get rows where the values in the array column are above a threshold value. I've been trying to achieve this using some of the array functions (arrayFilter and arrayExists) but I'm not familiar enough with the SQL/Clickhouse query syntax to get this working.
I've created the table using:
CREATE TABLE IF NOT EXISTS ArrayTest (
date Date,
sessionSecond UInt16,
distance Array(UInt16)
) Engine = MergeTree(date, (date, sessionSecond), 8192);
Where the distance values will be distances from a certain point at a certain amount of seconds (sessionSecond) after the date. I've added some sample values so the table looks like the following:
Now I want to get all rows which contain distances greater than 7. I found the array operators documentation here and tried the arrayExists function but it's not working how I'd expect. From the documentation, it says that this function "Returns 1 if there is at least one element in 'arr' for which 'func' returns something other than 0. Otherwise, it returns 0". But when I run the query below I get three zeros returned where I should get a 0 and two ones:
SELECT arrayExists(
val -> val > 7,
arrayEnumerate(distance))
FROM ArrayTest;
Eventually I want to perform this select and then join it with the table contents to only return rows that have an exists = 1 but I need this first step to work before that. Am I using the arrayExists wrong? What I found more confusing is that when I change the comparison value to 2 I get all 1s back. Can this kind of filtering be achieved using the array functions?
Thanks
You can use arrayExists in the WHERE clause.
SELECT *
FROM ArrayTest
WHERE arrayExists(x -> x > 7, distance) = 1;
Another way is to use ARRAY JOIN, if you need to know which values is greater than 7:
SELECT d, distance, sessionSecond
FROM ArrayTest
ARRAY JOIN distance as d
WHERE d > 7
I think the reason why you get 3 zeros is that arrayEnumerate enumerates over the array indexes not array values, and since none of your rows have more than 7 elements arrayEnumerates results in 0 for all the rows.
To make this work,
SELECT arrayExists(
val -> distance[val] > 7,
arrayEnumerate(distance))
FROM ArrayTest;
