kandi X-RAY | wk Summary
The goal of wk is to provide lightweight R, C, and C++ infrastructure for a distributed ecosystem of packages that operate on collections of coordinates. First, wk provides vector classes for points, circles, rectangles, well-known text (WKT), and well-known binary (WKB). Second, wk provides a C API and set of S3 generics for event-based iteration over vectors of geometries.

QUESTION
Situation: I have two dataframes df1 and df2, where df1 has a datetime index based on days, and df2 has two date columns 'wk start' and 'wk end' that are weekly ranges as well as one data column 'statistic' that stores data corresponding to the week range.
What I would like to do: Add to df1 a column for 'statistic' whereby I lookup each date (on a daily basis, i.e. each row) and try to find the corresponding 'statistic' depending on the week that this date falls into.
I believe the answer would require merging df2 into df1 but I'm lost as to how to proceed after that.
Appreciate any help you might provide! Thanks!
df1: (note: I skipped the rows between 2019-06-12 and 2019-06-16 to keep the example short.)

QUESTION
I have a macro that I use in Excel 2010 to loop through some xls files, extracting the data from each into a xlsm file. There should be about 195,000 rows from across all of the xls files, but after running it I end up with closer to 90,000. If I run it on only a few of the files at once I get the correct number so it seems to be something to do with the volume I'm trying to incorporate, but I understand that an xlsm can handle up to a million rows so that shouldn't be a problem, should it?. I've split the source files into batches in the past but I'd rather avoid doing that if possible. Ultimately, I'm trying to compile a csv to import into a SQL database. If anybody has any suggestions, I'd be very grateful.
Thanks.
PS I've asked about this before a month or so ago but as I'd totally misdiagnosed the issue and was asking about the wrong thing, I'm writing a fresh question so that I don't set people off on the wrong track. I was rightly chastised for not including enough code last time. This is the subroutine which extracts the data:

QUESTION
Is it possible to create a weakref of a pydantic model ?
...ANSWER
Answered 2021-May-29 at 21:41From documentation
Without a weakref variable for each instance, classes defining slots do not support weak references to its instances. If weak reference support is needed, then add 'weakref' to the sequence of strings in the slots declaration.
So just add __weakref__
to your __slot__
in your model
QUESTION
Let me start by saying that I am somewhat new to SQL/Snowflake and have been putting together queries for roughly 2 months. Some of my query language may not be ideal and I fully understand if there's a better, more efficient way to execute this query. Any and all input is appreciated. Also, this particular query is being developed in Snowflake.
My current query is pulling customer volumes by department and date based on a 45 day window with a 24 day lookback from current date and a 21 day look forward based on scheduled appointments. Each date is grouped based on where it falls within that 45 day window: current week (today through next 7 days), Week 1 (forward-looking days 8-14), and Week 2 (forward-looking days 15-21). I have been working to try and build out a comparison column that, for any date that lands within either the Week 1 or Week 2 group, will pull in prior period volumes from either 14 days prior (Week 1) or 21 days prior (Week 2) but am getting nowhere. Is there a best-practice for this type of column? Generic example of the current output is attached. Please note that the 'Prior Wk' column in the sample output was manually populated in an effort to illustrate the way this column should ideally work.
I have tried several different iterations of count(case...) similar to that listed below; however, the 'Prior Wk' column returns the count of encounters/scheduled encounters for the same day rather than those that occurred 14 or 21 days ago.
...ANSWER
Answered 2021-May-25 at 16:45I'm struggling to understand your requirement but it sounds like you need to use window functions https://docs.snowflake.com/en/sql-reference/functions-analytic.html, in this case likely a SUM window function. The LAG window function, https://docs.snowflake.com/en/sql-reference/functions/lag.html, might also be of some help
QUESTION
I have the query below that assigns a station volume based on the volume processed that week. Station sizes are based by looking at 4 data points throughout the year. This is because station fluctuate in volume throughout the year for example, they may have small volume in one quarter, but large in another. The goal is to assign a size to a station that will best suite it the entire year. The sql below gets together the four data points that will be needed to evaluate what size a station_size will be applied. There are multiple combinations of volume possibilities that can take place over the year which is why they are stored in a separate table. I have a separate table called "station_sizes" that provides the logic for what the station size will be based on the volume taken from the four point in time.
For example if a station processes small volume in wk 14 and small volume in wk27 and standard volume in wk 40 and small volume in wk 47 then they would be a ds small station size. There are 1000s of scenarios in the station_size table.
I want the final output to be the excerpt from the query output + station_size. The station size will be pulled from the station_size table.
I need to know how to have the query below reference the station size table so that it can identify for each year group is wk_16= xyz.. and wk_26 =xyz.. and wk_39 = xyz.. and wk_43 =xyz then it will pull in the size logic form the station size table.
For the ar section in the query. I want the logic to be if a station has "Yes" for AR at a minimum it needs to be a standard station size. I am not sure if I did that peice right. I am fine if its bigger than that but no smaller.
...ANSWER
Answered 2021-May-18 at 18:11I have added a condition for station_size. Please check whether you are looking for it or not.
QUESTION
Good morning, I am newish to SQL and would really appreciate some help. I am using the following query but do not want the "ar" column or second occurrence of the "station_ref column". When I try to remove it in the group by area it I get an area saying it "not in aggregate function". Also I am trying to link this output with another table named "station_sizes" where based on wk # it assigns a size to a station. For example if a station is small at wk 20 and standard at wk 48 then it will be a standard size. The station_size table outlines 100s of different scenarios and what size a station will be.Refer below for what the table looks like.Can you please help.Thanks!
...ANSWER
Answered 2021-May-18 at 15:52I'm still not sure if I completely understand your question but if you mean to have only one station_ref
column than you should only have one case since each case will produce a new column.
