How Can I Efficiently Paginate Data in SQL Server for Accurate Results?

SQL Server efficient paging query and accurate result acquisition

In SQL Server, paging (splitting data into multiple pages) is crucial for managing large result sets. In order to get the best performance and accurately calculate the total number of results, it is important to understand the best paging method.

SQL Server 2012 and later versions: Simplified method

Microsoft SQL Server 2012 and later introduces simplified and efficient paging methods: OFFSET and FETCH clauses. For example, you need to get the next 10 rows of data:

<code class="language-sql">SELECT * FROM TableName ORDER BY id OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY;</code>

This query ensures that the results are sorted and only the requested rows are retrieved.

Notes on using OFFSET and FETCH

When using OFFSET and FETCH clauses, keep the following points in mind:

• ORDER BY must be used: ORDER BY must be specified when using OFFSET and FETCH.
• OFFSET requires FETCH: OFFSET cannot be used alone and must be used together with FETCH.
• cannot be combined with TOP: TOP cannot be combined with OFFSET and FETCH in the same query.
