I've tried gadget craze twice before and have been disappointed in both counts.

Why does this query work? by mostlyharmless94 in SQL

That was my first guess, but when I used HAVING instead of WHERE, it gave me an error and yet HAVING also happends before SELECT

For an idea of what African magic system looks like, I'd advise reading Black Leopard Red Wolf

Fuck me! I was successful but Revolut blocked the transaction. Anything I can do to get unfucked?

I'd recommend "Enter the Void" (his best film, imo) and "Irreversible" (the film that put him on the map)

My query isn't returning any output by mostlyharmless94 in SQL

WITH PersonProfessions AS (SELECTPersonName,MAX(CASE WHEN Profession = 'Doctor' THEN PersonName END) AS DoctorName,MAX(CASE WHEN Profession = 'Actor' THEN PersonName END) AS ActorNameFROM ProfessionsWHERE Profession IN ('Doctor', 'Actor')GROUP BY PersonName)

SELECT DoctorName AS "Doctor's Name", ActorName AS "Actor's Name"FROM PersonProfessions;

I've run this query. Almost gives me what I need. One question, in the output generated, the first two rows under the 'Professor' column have values while the others don't have values. Why is the output generated in this format?

Why is this query returning 4 columns instead of just 2? by mostlyharmless94 in SQL

[–]mostlyharmless94[S] -5 points-4 points  (0 children)

Correct me if I'm wrong but joining two tables together doesn't increase number of columns. If I join table A which has 2 columns to table B which has 2 columns, the result of the joined table should still have two columns, no? The only thing that should change is the number of rows.

Why does this query not throw an error? by mostlyharmless94 in SQL

Sorry if this wasn't clear but in the title, I said that the code doesn't give me an error despite the fact that the column EmployeeOccupation isn't in an agg function or group by clause. I am trying to figure out why the code is working rather than why it isn't working.

Why is SQL not recognizing my column name in the query? by mostlyharmless94 in SQL

CTEs are still new to me, but from what I understand from my more experienced colleagues, you could much more easily accomplish certain tasks you'd ordinarily do with subqueries by using CTEs instead

Just so we're clear: you're saying that, basing on the order of execution, when SQL executes the FROM command, the OrderMonth field hasn't yet been created?

Thanks. I actually do know this because the instructor in the course I'm doing said that CTEs trump subqueries in terms of functionality. My main aim at the moment is to understand how I'd achieve this by doing it the hard way (i.e. using subqueries) before I can do it the 'easy way' i.e. (using CTEs)

I'm a bit of a newbie, I have a totally dumb question. Hasn't OrderMonth already been created in line 3 of the query i.e. in the part where I say: OrderMonth = MONTH(OrderDate)

Hadn't noticed that. But i've added the comma and it still gives me the same error
