"SQL Query of the Month: Win a BTC Prize - Show Off Your SQL Skills!"

[suggar]

Hey guys, let's kick off this SQL Query of the Month challenge with a chance to win some sweet BTC prizes. For those who may be new here, the goal is to come up with the most efficient and effective SQL query that solves a given problem. This month, the problem is: Write a query to find the top 5 products with the highest average rating, along with the product name, average rating, and number of reviews.

"Hey guys, got a pretty sweet query to share. How about this one: `SELECT * FROM orders WHERE total_amount > (SELECT AVG(total_amount) FROM orders) ORDER BY total_amount DESC LIMIT 10`? I'm guessing it's a decent way to pull the top 10 orders above average value"

"Whoa, nice prize! I just threw in a query that joins 3 tables to find duplicate orders. Here it is: `SELECT * FROM orders JOIN customers ON orders.customerID = customers.customerID JOIN order_items ON orders.orderID = order_items.orderID GROUP BY customers.customerID HAVING COUNT(order_items.itemID) > 1;` Good luck, mates!"

"Dude, I was thinking of answering this, but I don't wanna give away my chances. Can we get the query before we start cranking out answers? Let's see what we're working with."

"Hey guys, I'm gonna give it a shot. Here's my query: `SELECT * FROM table ORDER BY column ASC LIMIT 10 OFFSET 5;` What's the prize for the most efficient query? Did you guys see the rules about using subqueries?"

"Hey guys, just wanted to say I'm stumped on this one. Got a decent grasp on the basics but the advanced query is kicking my butt Anyone have a hint or a working solution for the 'Find the 5 most expensive items sold this quarter' query?"

"Dude, I just threw in a simple query to show my basic SQL skills. My query is: 'SELECT * FROM users WHERE balance > (SELECT AVG(balance) FROM users)'. Is it even competitive or am I just a SQL noob? "

"Yooo, just dropped in with a query to share - how about this one: `SELECT * FROM table_name WHERE column_name IN (SELECT column_name FROM another_table)`? Anybody got a similar query that's more complex and can beat this? I'm down for the BTC prize if I win "

 

[Polinter]

Yo, just a heads up, if I recall correctly, the previous winner's query was super specific to a MySQL database, so make sure your query can handle different DB systems. I'll give it a shot, but my SQL skills are a bit rusty What's the query for this month?

"Dude, I think I've got a solid query for this competition. How about: 'Find the top 5 most expensive transactions in the block where the sender's wallet address contains 'bitcoin.org''? Any ideas on the SQL syntax for this?"
