new to SQL, in problem 1 it seems like you aliased The game table as ga and the goal table as go, however you didn’t use AS to do so. Is this a normal practice? I have not learned that way before and it seems like a small time saver I will implement if so

Coding question 4 makes no sense to me. I wrote the following and got the wrong answer, and different output to your solution, even though they look identical in what they are doing? SELECT ac.name FROM actor ac JOIN casting ca ON ac.id = ca.actorid GROUP BY ac.name HAVING COUNT(CASE WHEN ca.ord = 1 THEN 1 ELSE 0 END) >= 15 It should be essentially the same, since in your solution you are counting the name, because it was already filtered to only include ord = 1 and grouped by name. In mine we grouped by name, and counting the occurences of ord=1, it should return the same value, and the same names, why doesn't it?
@AaronMOliverАй бұрын
Good question! What your solution is doing is actually not counting occurences of ord=1, it is just counting all rows in the resulting set. Try changing the COUNT to SUM and see if that works!

hi, the coding question5 list the people who have worked with.... may I ask you why don't we direct write" where name=...." not sub query?
@OnePercentPerfectionist2 ай бұрын
Thanks for this. I attempted the last one before watching your solution. I didn't need to go to the movies table since the movie ids were already on the casting table. But I really like how you explained generally. Great video. Please make more. :)

In 2023 (or 2024), learn Julia! It's come a long way in the last few years. R and Python are still great choices but they're far from the only options these days for data science.

I know this video is old, but like when you mentioned jupyter notebooks for python, it's kinda baffling that you didn't mention the fact that R should be fully support in jupyter, since the idea with those is mixed code blocks. So you can have markdown blocks and python blocks and R blocks, Julia and even c blocks if you hack it enough. I watched this video because I'm already fairly proficient in python and was thinking should I learn R and when you mentioned both, Jupyter is the first thing that comes to mind

Name one (1) of the top 25 department of statistics in the world that use Python to analyze data? I'll wait. What do "you" (impersonal) now about data analysis that statisticians do not know? Python wastes a lot of time to do some simple data analysis tasks.

SQL is a coding language used to interact with relational databases MySQL is a software used to implement those relational databases
@aidanthompson5053 Жыл бұрын
SQL is an abstraction; a language - there’s no implementation involved, just coding syntax MySQL is a piece of software, a relational database management tool that allows you to: use a graphical interface to update schemas, to define data types to give users permissions or revoke them etc.

There are 4 main types of joins: Inner, outer, left, right An inner join retrieves records that have matching values in both tables involved in the join An outer join retrieves records where there is a match in either the left or right table Left join retrieves records from the left table and the matched records from the right table Right join retrieves records from the right table and the matched records from the left table

A primary key is a unique, non-nullable identifier for each record in a table and it can be either 1 column or multiple columns. However, each table can only have one primary key.

i started R almost 1,5 years and am enjoying the tool. however many colleagues only use Python and seem to be annoyed with the R code. this is due to the fact that my company is working with MS tools, and microsoft decided to go all in with Python. i feel the pressure to learn coming closer.
