SQL
Implementing Database Pagination with LIMIT and OFFSET
Efficiently retrieve a specific range of records from a large dataset for client-side pagination, using SQL's LIMIT and OFFSET clauses for performance.
SELECT id, name, created_at
FROM products
ORDER BY created_at DESC
LIMIT 10 OFFSET 20;
How it works: This SQL snippet demonstrates how to implement pagination by selecting a specific 'page' of results. The 'LIMIT' clause restricts the number of rows returned (e.g., 10 rows per page), while the 'OFFSET' clause skips a specified number of initial rows (e.g., 20 rows to get the third page if each page has 10 items). It's crucial for managing large datasets in web applications, allowing users to browse through data without loading everything at once.
