MySQL: FKs to non-unique column

Asked 2021-Jun-03 at 19:14

As I found out to my surprise MySQL allows FKs to non-unique columns. I am not sure if this applies to other databases as well and always thought the FK had to be unique - otherwise, how do we know the parent row of a child - but looks like that is not the case. Here is a fiddle that illustrates this. We first create 3 tables:

...

Answered 2021-Jun-03 at 19:04

A foreign key relationship is not defining a "parent" relationship. It is simply saying that a combination of key values is present in another table.

In practice and in the definition of SQL, the referenced value should be unique (and preferably a primary key). This is required in almost all databases.

MySQL extends this definition to allow any indexed columns.

QUESTION

Grouping by country and discipline in SQLServer

Asked 2021-May-30 at 15:59

i've got a problem I cannot solve in SQLServer. There are 3 tables with data about the Olympics.

Table 1: Dysciplines - contains DisciplineID (int,PK) and Discipline (varchar)

Table 2: Athletes - contains AthleteID (int, FK), Athlete (varchar, PK), Nationality (varchar) and DisciplineID(int,FK)

Table3: Medals - contains AthleteID(int, PK), Year(int) and Medals(int)

I want to extract all the countries, that got more medals in their best discipline than in all the others combined. However, I am having problem with it.

Obviously I joined all the tables, but I'm not sure how do I continue. I tried:

Answered 2021-May-30 at 15:59

You would use aggregation and having. Start with the number of medals in each discipline in each country:

Since you've already computed counts, you should use bar() instead of hist(). A standard way to to plot grouped counts is with groupby()-unstack():

OR-tools CVRP with a distance constraint not working

I am using the OR-tools code to optimize bus routes with distance and capacity constraints. This is the output that I got:

ANSWER

Answered 2021-Apr-15 at 07:13

By default, the arc cost for empty route aka Start -> End is zero.
So your last two vehicle routes, being empty, will return 0 when using routing.GetArcCostForVehicle(previous_index, index, vehicle_id).

You can enable the cost using RoutingModel::ConsiderEmptyRouteCostsForVehicle(bool consider_costs, int vehicle).

Something like this should work IMHO:

QUESTION

Is there a way to find the mean length of words in a string in R?

Asked 2021-Apr-05 at 10:35

I am new to R and Webscraping. As practice I am trying to scrape information from a fake book website. I have managed to scrape the book titles, but I now want find the mean word length for each individual word in the book titles. For example, if there were two books 'book example' 'random books' the mean word length would be 22/4 = 5.5. I am currently able to find out the mean length of the full book titles, but I need to split them all into individual words, and then find the mean length.

Code:

ANSWER

Answered 2020-Dec-24 at 13:04

print(strVal[-1:-1-X:-1])

You need to print the slice of strVal. Not just the indexes.

I also changed the indexes to get the right result.

MapReduce Hadoop on Linux - Change Reduce Key

Asked 2020-Dec-09 at 20:26

I've being searching for a proper tutorial online about how to use map and reduce, but almost every code about WordCount sucks and doesn't really explain you how to use each function. I've seen everything about the theory, the keys, the map etc, but there is no CODE for example doing something different than WordCount.

I am using Ubuntu 20.10 on Virtual Box and Hadoop version 3.2.1 (if you need any more info comment me).

My task is to manage a file that contains several data for athletes that took place on the Olympics.

You will see that it contains a variety of info, like name, sex, age, weight, height etc.

I will show an example here (hope you understand it):

ANSWER

Answered 2020-Dec-01 at 17:37

The core idea about MapReduce jobs is that the Map function is used to extract valuable information from the input and "transform" it to key-value pairs, where based on them the Reduce function is gonna be executed for each key separately. Your code seems to show a misunderstanding about the ways of execution of the latter, but that's no biggie, because this is a proper example of the WordCount example.

Let's say we have a file with stats of olympic athletes and their medal performance like you showed under a directory named /olympic_stats in the HDFS as shown below (you see I included records with the same athlete as this example needs to work upon):
