sherlock | GitHub Actions toolkit to monitor a repository and run | Continous Integration library

I am learning web development, and I tried to do the exercise, but the answer given is different from mine. May, anyone please help me see what my mistake is.

Here is the code:

Usual disclaimer: I'm very much a novice when it comes to Tableau (and R, which is my preferred data wrangling language).

Here's what I'm trying to do:

I have a dataset which has multiple variables, two of which are "time" and "genre". Here's an example of what the data looks like:

...

I'm having the following results from my sql query:

id sp_firstname sp_lastname member_firstname member_lastname 1 NULL NULL John Smith 2 Dejuan McLaughlin NULL NULL 2 NULL NULL Jack Sparrow 3 John Walker NULL NULL 3 NULL NULL Sherlock Holmes 4 Mellie Durgan NULL NULL 4 NULL NULL John Waston 5 Lucy Snider NULL NULL

Whereas what I need to achieve is this:

id sp_firstname sp_lastname member_firstname member_lastname 1 NULL NULL John Smith 2 Dejuan McLaughlin Jack Sparrow 3 John Walker Sherlock Holmes 4 Mellie Durgan John Waston 5 Lucy Snider NULL NULL

Basically, I need to somehow merge pairs of rows that sort of have nulls crosswise.

After looking through SO answers, I could only find variants of this problem when NULL values needed to be substituted by numbers, and in that case people used max function combined with group by.

However I have several joins in my table and my NULL values need to be substituted with strings, not numbers, so max wouldn't really work here (as I thought).

Here's my sql code:

I read a snippet and confusing and could not find the rules or principle to explain that,the output is Malibu,why not London,the adress: sherlock.address in let john = { surname: 'Watson', address: sherlock.address }; is to assign the value ofsherlock.adress to john.address,but not overwrite sherlock.adresswithjohn.address.How could I fiddle my hair.

In this java program I am trying to search if an ISBN number exists in the "Book" type array or not. But when I try to implement the method and display the output, I am getting an error which says " The method searchBook(Book, String) is undefined for the type Book". The <-- HERE comment shows where the error pops up. I do not understand how to rectify this error and any help will be appreciated. Thank you.

I have a situation which is quite similer to below depiction of example tables

I have "School" table

SchoolId SchoolName PrincipleId SchoolPrincipleName 1 South Texas 1 Julia Petersson 2 North Texas 2 Schon Jakobs 3 Centr Texas 3 Elina Sherlock

Above table has de-normalised column SchoolPrincipleName

There is another ViewSchoolWithOutPrinciple database view

SchoolId PrincipleId IsSchoolWithOutPrinciple 1 1 True 2 2 False

Now i have to do correction of SchoolPrincipleName column in"School" table based on ViewSchoolWithOutPrinciple database view

I have to update SchoolPrincipleName column inside "School" table to empty or null for those rows which has SchoolId and PrincipleId existing in ViewSchoolsWithOutPrinciple and IsSchoolWithOutPrinciple is equal to True

Below SQL is symbolic representation so it doesn't meant to work.

This question comes off the back of the great question and answer at:

Stackoverflow: Why does a UIStackView with a single view, fill Proportionally, and Layout Margins causes ambiguous constraint error?

I am having similar issues but with embedded stackviews inside a scrollview. I have modified the explanation code from the above question. In my working code, I have a parentVC that loads into a container view, a childVC that has the embedded scrollView and stackViews (outer stackview is vertical and then each of its subviews are a bunch of horizontal stackviews). There are a range of options from fixed width label, icons and expanding labels.

The problem is I either get UISV-spacing constraint errors or trailing errors for the expanding labels. I understand from the above question that this has to do with the sequence of how the auto layout engine is calculating the proportional widths, spacing etc. but have no idea how to fix. Any suggestions would be welcome. I'm attaching the code I'm using:

I am working on a product page where the user has an option to filter on different boardgames. What I want to do is to give the user an option to filter on time, category of the game, number of players and age. When the user enters a checkbox on all 4 options there should be some games recommended based on the criteria. However when I check multiple boxes I get no result, what am I doing wrong? (I have more games in my file but post small amount)

Here's my code:

I would like to implement functionality for being able to search a QPlainTextEdit for a query string, and display all matched lines in a table. Selecting a row in the table should move the cursor to the correct line in the document.

Below is a working example that finds all matches and displays them in a table. How can I get to the selected line number in the string that the plaintextedit holds? I could instead use the match.capturedEnd() and match.capturedStart() to show the matches, but line numbers are a more intuitive thing to think of, rather than the character index matches.
