Efficiently Paginate Query Results in SQL
Learn how to implement efficient pagination in your SQL queries using LIMIT and OFFSET to retrieve a specific subset of data, crucial for displaying large datasets on web pages.
SELECT id, title, created_at
FROM posts
ORDER BY created_at DESC
LIMIT 10 OFFSET 20;
How it works: This SQL snippet demonstrates a common method for pagination using `LIMIT` and `OFFSET`. `LIMIT 10` restricts the result set to 10 rows, and `OFFSET 20` skips the first 20 rows. This means the query will return rows 21 through 30, perfect for displaying the third page of results (assuming 10 items per page). This approach is highly efficient for most database systems when paired with appropriate indexing on the `ORDER BY` column.
