MySQL 8.0: Difficulty retrieving unique rows from multiple JOINs using DISTINCT and GROUP BY
I'm getting frustrated with I'm experimenting with I've looked through the documentation and I'm still confused about I've searched everywhere and can't find a clear answer. I'm facing an issue in MySQL 8.0 where I'm trying to retrieve unique rows after joining multiple tables, but the results are not as expected. I have three tables: `users`, `orders`, and `products`. The goal is to fetch a distinct list of users along with the products they ordered, but I'm getting duplicates in the results. Here's the query I'm currently using: ```sql SELECT DISTINCT u.id, u.name, p.product_name FROM users u JOIN orders o ON u.id = o.user_id JOIN products p ON o.product_id = p.id; ``` Despite using `DISTINCT`, the query returns rows with the same user appearing multiple times if they've ordered more than one product. I've also tried using `GROUP BY` like this: ```sql SELECT u.id, u.name, GROUP_CONCAT(p.product_name) AS products FROM users u JOIN orders o ON u.id = o.user_id JOIN products p ON o.product_id = p.id GROUP BY u.id, u.name; ``` This approach returns the unique users but concatenates their products into a single string, which is not what I want. I need to see each user and their respective product(s) listed individually without duplicates, but retaining the relationship. Additionally, I've checked my data for duplicates and confirmed that the relationships are correct. I've also ensured that there are no extra spaces or hidden characters in the product names that could be causing perceived duplicates. Is there a way in MySQL to achieve the desired outcome of distinct users with their ordered products while avoiding any unintended duplicates? Any suggestions or best practices would be greatly appreciated! My development environment is Ubuntu. What's the best practice here? I'm working on a CLI tool that needs to handle this. What am I doing wrong? Has anyone else encountered this? I'm working on a service that needs to handle this. I'd be grateful for any help. For reference, this is a production desktop app. Any ideas what could be causing this?
