How to Implement Pagination in SQL Server 2008 Using ROW_NUMBER()?

Pagination in SQL Server 2008

Pagination, also known as paging, is a technique used to divide a large dataset into smaller, more manageable pages. This allows applications to retrieve data in smaller chunks, reducing the load on the server and improving performance, especially for large datasets.

In SQL Server 2008, pagination can be achieved using the ROW_NUMBER() function. The ROW_NUMBER() function assigns a sequential number to each row within a partition of a result set, starting at 1 for the first row in each partition.

Example:

Consider the following example where we want to paginate the data in the "MyTable" table and retrieve only the rows between the 10th and 20th page:

WITH CTEResults AS
(
    SELECT IDColumn, SomeField, DateField, ROW_NUMBER() OVER (ORDER BY DateField) AS RowNum
    FROM MyTable
)

SELECT *
FROM CTEResults
WHERE RowNum BETWEEN 10 AND 20;

In this example, the ROW_NUMBER() function assigns a sequential number to each row in the "MyTable" table, starting at 1. The results are then filtered to retrieve only the rows with RowNum values between 10 and 20, effectively retrieving the second page of data.

By utilizing the ROW_NUMBER() function, developers can easily implement pagination in SQL Server 2008 applications, enabling them to manage large datasets more efficiently and improve performance.
