Implementing Pagination in SQL Queries
Learn how to retrieve a specific range of rows from a large dataset, essential for displaying paginated results in web applications, using LIMIT and OFFSET.
SELECT
product_id,
product_name,
price
FROM
products
ORDER BY
product_id
LIMIT 10 OFFSET 20;
-- For page 1 (10 items per page): LIMIT 10 OFFSET 0;
-- For page 2 (10 items per page): LIMIT 10 OFFSET 10;
-- For page 3 (10 items per page): LIMIT 10 OFFSET 20;
How it works: This snippet demonstrates how to paginate results using `LIMIT` and `OFFSET`. `LIMIT 10` restricts the output to 10 rows. `OFFSET 20` skips the first 20 rows, effectively retrieving items 21 through 30. This is crucial for building user interfaces that display data in pages, improving performance and user experience for large datasets by only fetching necessary data.
