Implement Pagination with OFFSET and FETCH NEXT
Efficiently paginate large datasets in SQL queries using OFFSET and FETCH NEXT clauses to retrieve specific result sets, crucial for web applications.
SELECT
product_id,
product_name,
price
FROM
products
ORDER BY
product_id
OFFSET 20 ROWS
FETCH NEXT 10 ROWS ONLY;
How it works: This snippet demonstrates how to implement pagination in SQL. The `OFFSET 20 ROWS` clause skips the first 20 records, and `FETCH NEXT 10 ROWS ONLY` (or `LIMIT 10` in MySQL/PostgreSQL) then retrieves the subsequent 10 records. This is fundamental for displaying paginated results on a website, allowing users to browse through large sets of data without loading everything at once.
