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
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).
QUESTION
I've built a for loop that goes through the values of a list, enters them as keys for two dictionaries and multiplies the 2 key values together.
When you print, it gives each multiplied value on a new line.
I'd like to add the values together to get a combined total but thus far have not been able to.
...ANSWER
Answered 2019-May-09 at 20:43If I get you right and thinking in the simplest way, you can assign a variable and add up it in every iteration like:
QUESTION
I'm trying to count how many times a word within nested lists occur based on a different word list. For example:

word = ['pear','oranges','pineapple','scones','drawers']
output = []
# create a dict and populate with keys being unique words and values being its occurances
d = {}
for x in one:
for y in x:
d[y] = word.count(y)
# go through each word in sublist and find the count from the dict
for x in ne:
output.append([d[y] for y in x])
QUESTION
I am trying to get certain classes based off their id
from the database on the server side. The data sent from the server is in JSON format. The following is the JSON I am currently working with:
ANSWER
Answered 2017-Feb-18 at 09:59You are passing a non-array classes
to $.grep
(you probably intended classes.data
), and you are overwriting the previous assignment to classes
by the next in every iteration of the loop.
Instead, gather the id
values in an array, and then filter for those id
s that are in that array with Array#indexOf
(or Array#includes
in modern browsers):
