SQL Query for Efficient Data Pagination
Learn to implement efficient data pagination using SQL's LIMIT and OFFSET clauses to retrieve subsets of records for web application display.
SELECT id, product_name, price, stock
FROM products
ORDER BY product_name ASC
LIMIT 10 OFFSET 20;
How it works: This SQL snippet demonstrates how to paginate results from a database. The `LIMIT` clause specifies the maximum number of rows to return (here, 10 rows per page), while the `OFFSET` clause defines the starting point (skipping the first 20 rows, effectively showing page 3 if each page has 10 items). It's crucial for managing large datasets in web applications, preventing overwhelming data loads, and improving performance.
