rating_id movie_id member_id rating 19 10 39 2 10 56 41 1Now the question is:
Out of the total number registered members, how many have actually left a movie rating? Display the result as a percentage
This is what I have tried:
...ANSWER
Answered 2022-Apr-02 at 07:23You can use a cross apply
to determine using a sub-query whether a given member has left a rating or not (because you can't use a sub-query in an aggregation). Then divide (ensuring you use decimal division, not integer) to get the percentage.

. The rest are simple vectorial operations (add

I have a form with "Does this case have IR number?"
If yes, show fields. If no, hide and show others.
I am using
validate()
function.old()
to keep data after failed form submission, akavalidate()
error messages.- JQuery show/hide for the fields.
For the radio input, I used old()
like this:
ANSWER
Answered 2022-Mar-03 at 09:14Since the radio inputs have the same name, in both cases your session has "checkIR" and when you try to check it with old('checkIR')
it will return true regardless of its value. Thats why "No" is checked.
Therefore, in order to find the old selected one, you should check by its value, not whether it exists in the session or not.
Code like this should work for you;

I'm looking for help I'm trying to get some data of json file from an api that I'm using for student project ( I'm very beginner on API stuff).
I'm at the beginning of the project and they asked me to get all of the json file data on the homepage with all informations associated with :
Those are the data that I extract for the API
It's works fine and when the user click on one of the item it's show the same information but only the for the one clicked and this is where I'm stuck.
When I click on an item each of them have an id related to a link showing their own id :
The small code use through a loop to get all items id
So I create another js file for the product page where I have to implement them only with Javascript Vanilla and this is what I've tried :
...ANSWER
Answered 2022-Feb-15 at 15:10The JsDemo function has the query selector logic invoked only once outside the loop. The loop then goes through the array & overwrites all the properties in every iteration. So,at the end of the loop,the last element of the array will be used to populate values. You could move the query selector logic within the loop if your aim is to populate every card. You would have to use the index i.e. the i variable for that purpose.
The Html doesn't have an attribute marking the index of the card.If you want to keep the same html,you can use document.querySelectorAll() with the index i like below.

QUESTION
i downloaded imdb database and while i was able to import it into mysql, i coulden't put the genre column datatype to "SET", even tho imdb only has 21 genre's for movies, when i imported the data i set the genre data type to VARCHAR(255), and i can not change it to SET, is it possible? here's what i tried:
ALTER TABLE movies MODIFY genre SET('Drama', 'Comedy', 'Action', 'Crime', 'Romance', 'Thriller', 'Adventure', 'Horror', 'Mystery', 'Fantasy', 'Sci-Fi', 'Biography', 'Family', 'Animation', 'Music', 'History', 'War', 'Sport', 'Musical', 'Western', 'Film-Noir') NOT NULL;
and i get the error code 1265 "Data truncated for column 'genre' at row 2", I'm guessing that's because row 2 has more than only one genre, but i thought that's the difference between ENUM data type in SET, am i missing something?
...ANSWER
Answered 2021-Dec-01 at 23:26In MySQL, the SET data type requires no spaces between the values.

I have a dataset, where I need to find top 2 average rated movies for each genre. With the given layout of data, how can I achieve it? Can someone please help me understand a workaround?
In order to simplify it, I have created new columns which separates values from 'genres' into unique genres and assigned values 1 and 0 to it. So, the group by will be based on these new unique genres and not the 'genres' column. For example, if I filter on the column 'Comedy' to 1, the average rating for title 'abc', 'pqr','ghi', and 'mno' are 3.75, 2.9, 2.25, and 3.12 respectively. So, the top 2 movies based on the average rating for Comedy genre will be abc and mno. Similar logic will be followed for other unique genres.
My original dataset is very similar to the sample dataset below:
...ANSWER
Answered 2021-Nov-14 at 18:14You want to get the top 2 movies per individual genre, you first need to melt
the dummy variables, then groupby
