QUESTION
Dataset looks like this : This is a sample dataset for number of employee login activity named - activity
I need to calculate few metrics, was able to do in python data frames, but new in mySQL.
what is the average number of employee active per day for month of jan 2018 by dept ( was able to do somewhat half of it, but results coming are not correct.
number of unique active employee (login >0) per month for jan 2018 for each dept_id (was able to do it)
month over month growth for all dept_id from dec-2017 to jan 2018 where at least one employee was active (login >0) - no idea how to do this in sql
fraction of users who were active in each dept_id for dec 2017 and were also active in the same dept_id for jan 2018
how many employee login in on 3 or more consecutive days in jan 2018
Any help would be appreciated.

QUESTION
I have a dataset with the name of Danish ministers and their position from 1990 to 2020 (data comes from dataset called WhoGovern; https://politicscentre.nuffield.ox.ac.uk/whogov-dataset/). The dataset consists of the ministers name
, the ministers position
, the prestige
of that position, and the year
in which the minister had that given position.
My problem is that some ministers are counted twice in the same year (i.e., the rows aren't unique in terms of name
and year
). See the example in the picture below, where "Bertel Haarder" was both Minister of Health and Minister of Interior Affairs in 2010 and 2021.
I want to create a dataset, where all the rows are unique combinations of name
and year
. However, I do not want to remove any information from the dataset. Instead, I want to use the information in the prestige
column to combine the duplicated rows into one. The observations with the highest prestige should be the main observations, where the other information should be added in a new column, e.g., position2
and prestige2
. In the example with Bertel Haarder the data should look like this:
(PS: Sorry for bad presenting of the tables, but didn't know how to create a nice looking table...)
Here's the dataset for creating a reproducible example with observations from 2010-2020:

and the other for prestige_1

I am running a Java based application and it is crashing due to Insufficient memory. Some output snippet of hs_err :
...ANSWER
Answered 2021-Mar-04 at 01:48You've used -Xms to force the JVM to get ~30GB at JVM startup.
It has tried, and failed. It only obtained 8GB. It needs another 22-ish GB but cannot get it. That is what the error message is telling you. This is consistent with a dump that says the heap is only 8GB.
You're asking for more than the OS will provide. You'll need to figure out what's going on in the OS in general.
Your application code is probably not involved. The JVM is still initializing its heap in accordance with your command-line options.

QUESTION
I try to draw line COVID cases for each date. I do not have output, the lecturer gave just questions. I solved the question but my problem is the output. It looks weird. Here is the question: "For the ten countries with the highest absolute number of total deaths, draw the following line graphs to visualize whether epidemic has started to slow down and how the growth rate of new cases/deaths differs across those countries. a) Number of new cases at each date (absolute number vs per 100.000 population)"
Here is my codes:
...ANSWER
Answered 2021-Jun-09 at 13:27Looking at Belgium, I get total deaths = 25051 from your data file, which tallies exactly with the data here.
It's obvious that the highest value (by far) for every country occurs "on" the earliest date for the country in the file. Amongst your top ten (I agree with your selection), this is 01Mar2021 for every country apart from Spain, and 28Feb2021 for Spain.
These two facts lead me to conclude (1) your graphs correctly display the data you have asked them to summarise and that (2) you have a data artefact: the first record for each country contains the cumulative total to date, whereas subsequent dates contain data reported "in the previous 24 hours". I use quotes because different countries have different reporting conventions. For example, in the UK (since August 2020) "COVID-related deaths" are deaths from any cause within 28 days of a positive COVID test. Citation
Therefore, to get meaningful graphs, I think your only option is to discard the cumulative data contained in the first record for each country. Here's how I would do that:
QUESTION
I have this activity where I have to use star growth in a string where it grows with the amount of a character in the string. Here is an example: star_match_growth("incandescent", "c") and have it return as: inc*andesc**ent and have it continue if there are any more c's in the string. This is what I have to far:
...ANSWER
Answered 2021-Jun-07 at 23:36You can provide re.sub
with a callable (function, lambda, etc.) which must accept a single regex match-object as an argument, and which must return a string with which to replace that match. In my snippet, I'm taking advantage of a persistent default argument it
, which is an iterator that yields ascending integers (starting at 1 in this case). The state of the iterator is preserved between invocations, which has the effect of appending more and more stars to subsequent matches:

QUESTION
I would like to convert NCBI's Biosample Metadata XML file to CSV, or RDF/XML as a second choice. To do that, I believe I have to learn more about the structure of this file. I can run basic XQueries in BaseX*, like just listing all values, but then I've been using shell tools like
sort|uniq -c
to count them. I have heard about XSLT
transformations and GRDDL
in passing, but I don't think a style sheet is provided for this XML document, and I don't know how to create or discover one.
For example, can I get a count of the number of s for each ? Are there any
with more than one primary
? What are the most common db attributes of the primary Ids?
Here's a query that shows my maximum level of XQuery sophistication at this point:
