How to use Key-Centric Pagination In SQL
Similar to keyset pagination, key-centric pagination relies on unique keys but provides more flexibility in navigation by directly using the primary key of the table.
SELECT id,name, price, category
FROM products
WHERE id > 5
ORDER BY id
LIMIT 5;
Output:
Key-Centric Pagination
Explanation: This output also displays the first 5 rows starting from where the last page ended. By the same token, we use WHERE id > 5 for taking the rest of the rows with IDs above the highest ID of the previously fetched rows. The result set will feature products with identities from 6 to 10, put in ascending order of their IDs, combined with info like product names, prices, and categories. The method enables users to navigate efficiently as it directly uses the primary key of the table as a way of managing the pagination.
What are Different Methods to Do Pagination in PostgreSQL?
In the area of database management, PostgreSQL has a diversity of methods to optimally implement pagination traversing over a range of data retrieving needs.
From traditional set-based pagination to very advanced keyset pagination and window functions, PostgreSQL has a wide range of techniques that are accessible by both database administrators and developers to easily process large datasets.
In this article, We will learn about the Different Methods of pagination in PostgreSQL by understanding various methods along with the practical implementation of the method and so on.
