SQL
Efficient Database Pagination with LIMIT and OFFSET
Learn to efficiently paginate large datasets in SQL using LIMIT and OFFSET clauses, crucial for building fast and scalable web applications.
SELECT
product_id,
product_name,
price
FROM
products
ORDER BY
product_id
LIMIT
10
OFFSET
20;
How it works: This SQL query retrieves a specific "page" of results from the `products` table. The `ORDER BY` clause is essential to ensure consistent ordering across pages. `LIMIT 10` specifies that 10 rows should be returned, and `OFFSET 20` skips the first 20 rows, effectively returning rows 21-30. This technique is fundamental for implementing pagination in web interfaces.
