Row offset in SQL Server: Skip unnecessary rows
Unlike other SQL databases, SQL Server lacks an explicit OFFSET clause. This can create challenges when you need to get results from a specific offset without retrieving all leading rows. To overcome this limitation, consider the following strategies:
SQL Server 2005 and above
Use the OVER() clause:
SELECT col1, col2 FROM ( SELECT col1, col2, ROW_NUMBER() OVER (ORDER BY ID) AS RowNum FROM MyTable ) AS MyDerivedTable WHERE MyDerivedTable.RowNum BETWEEN @startRow AND @endRow
SQL Server 2000
Efficient result set paging:
-
Use efficient paging techniques, such as using computed cursors or relying on a custom paging mechanism.
-
Please refer to the following methods:
- Methods for efficient paging of large result sets in SQL Server 2000
- A more efficient way to paginate large result sets
Other instructions
- Specify specific columns instead of relying on SELECT * to optimize performance.
- Evaluate the feasibility of using different data sources or middleware that support the OFFSET clause to increase flexibility.
