Day 30: Limiting Data with LIMIT in MySQL

Today, let us explore the LIMIT clause in MySQL, which helps control the number of records retrieved from a query. It's a great way to optimize performance and fetch only the most relevant data!

? Improves query performance by reducing the dataset size

? Fetches top results (e.g., top 10 customers, latest orders)

? Efficient pagination when working with large datasets

?? Practical Examples:

1. Retrieving Only 5 Records

SELECT * FROM users
LIMIT 5;        

2. Fetching the Top 3 Oldest Users

SELECT * FROM users
ORDER BY age DESC
LIMIT 3;        

3. Getting the Most Recent Orders

SELECT * FROM orders
ORDER BY order_date DESC
LIMIT 10;        

4. Skipping Records with OFFSET (Pagination Purpose)

SELECT * FROM users
LIMIT 5 OFFSET 10;
-- Retrieves 5 users starting from the 11th record        

?? Key Takeaways:

? LIMIT helps improve query efficiency

? OFFSET allows skipping records, making pagination easier

? Commonly used with ORDER BY to fetch the most relevant data

Do you use LIMIT in your SQL queries? Let's discuss!
