QUESTION
Using the w3schools.com SQL tutorial Northwind database, I'm trying to display the category that has the most products shipped. Additionally, I want to display the net income from all sales in that category. I can't figure out how to take the category with the most products shipped, and use the amount of products shipped to calculate the net income of that category. This is because there are many different products that have the same CategoryID but different prices.
...ANSWER
Answered 2021-Jan-25 at 07:24So first of all you get the income for each product and category and then based on that you find total income for that category and you do this with the help of subquery, then you join this resultant table with the category table and with the help of group by you find the product count and total income for each category, below is the sql query for more indepth understanding
QUESTION
I'm trying to store an array of json objects into local storage and I have no idea why it's not working. I've tried to use localStorage.setItem('comparisons', JSON.stringify(setComparisons))
but nothing gets stored for some reason.
I know the array I'm storing has the information I'm trying to store because it's all there when I log the array in the console before storing it.
I've also stored similar objects (not arrays of said objects though) in localStorage and retrieved them without any problems. I don't know if it's because of this being an array nested with arrays of arrays or what, but I can't figure it out.
Here is my code:

QUESTION
i'm newbie in neo4j and need help with my case... i'm trying to load json file with the structure (updated by suggested) like below and extract into 3 nodes (big5_personality, personality_result & personality)
...ANSWER
Answered 2020-Jul-15 at 03:29You have multiple issues with your data file. Among them are:
Your Cypher code expects
personality_result
to be a list of JSON objects. It is not.(a) It is a single string, not a list.
(b) That string seems to consist of the truncated start of a stringified JSON object (that includes a lot of extra pretty-printing whitespace).
So, everything in your Cypher query starting at the
FOREACH
will not work.In your next-to-last
MERGE
,personality_result.personality
should probably be justpersonality
.
You may have other issues, but it is hard to tell until you fix your data file and code.
QUESTION
Here is a picture that shows this annoying pop up:
Today I updated Intellij to 2020.1, and that's when I first saw this. It's not fixed mind you. It pops up whenever I hover over my code, which greatly distracts me. Even after disabling all plugins it persists. How can I banish this eyesore to the fiery depths of hell where it belongs?

QUESTION
My scene continuously says is loading and not loaded and I can not play properly
I don't get any error message or warning. I don't know if there is a mistake in the code (if yes, I don't know which part to import here because it is too long), I don't think this is a common thing because I couldn't find anything in the forums related to this issue.
If there is a way to fix it please help.
It was working fine till I added this to Update()

ANSWER
Answered 2019-Dec-20 at 13:24You have health = 0;
in your Start()
, and if(health<=0) RestartGame();
in your Update()
, so your game is always restarting.
Try not to start the game with health = 0
and that's all I think.
QUESTION
I have a large dataframe consisting of tweets, and keyword dictionaries loaded as values that have words associated with morality (kw_Moral
) and emotion (kw_Emo
). In the past I have used the keyword dictionaries to subset a dataframe to get only the tweets that have one or more of the keywords present.
For example, to create a subset with only those tweets that have emotional keywords, I loaded in my keyword dictionary...
...ANSWER
Answered 2018-Dec-12 at 14:02Your requirement would seem to lend itself to a matrix type output, where, for example, the tweets are rows, and each term is a column, with the cell value being the number of occurrences. Here is a base R solution using gsub

QUESTION
I know how escaping works in general, but in this case, I cannot get it to give me the desired results.
I have a table with a list of cards in it. At the top of the command, I have the query push each card name into an array as a "master list." Later on in the code, I have the users provide card names they would like to add to their deck. In order to check that they are using cards that exist, exactly as spelled, it takes each card name the user provides and tries to find it in the master list array.
However, when the user provides a card name with an apostrophe in it (i.e. Drago's Fury
), it refuses to find the card name in the list.
I have tried replacing all occurrences of '
with \'
and ''
and several combinations of the two, multiple \'
s and multiple ' '
s in various amounts. Nothing seems to let me match it. Drago's Fury
in the table does contain the '
s in the name as expected, because I was able to put it into the table by escaping it with \'
.
Here's the code I have:
...ANSWER
Answered 2019-Jul-01 at 15:39As explained in the comments, by using placeholders (?
), the input is automatically escaped for you; the node-mysql
driver uses mysql.escape()
for them on its own. This will prevent injection and your current error, without you having to do anything else yourself. Your apostrophe won't trigger the same error since it's being read literally rather than as part of the statement.

QUESTION
Apologies if the title is confusing i wasn't too sure what else to call this question. Basically What I've accomplished so far is I've created a backup of a table ORDER_DETAIL and made the modifications to it so that when it runs the original data from table ORDER_DETAIL is inserted into a table ag715. The purpose of this is that when a separate script is ran called HACKER, this script changes ORDER_DETAIL.
My Task now is to compare the tables and show whats been deleted, inserted and updated. However my issue is when i run my backup file, ORDER_DETAIL is empty and ag715 has data so I'm unable to compare the tables.
My question is if my backup file was modified properly, or if its incorrect and deletes the contents of a table ORDER_DETAIL when ran?
...ANSWER
Answered 2019-Jun-08 at 00:00For this purpose, creating a new table maybe is not what you are looking for! Please review incremental backup solutions like Percona xtrabackup. I don't know why you do this, but maybe I should warn you, if you have some enterprise task, it is not a proper way to check the differences between data in the database layer! You should execute such processes at logic layer (with a proper programming language or scripting tools).
