I tried that initially, but that does not seem to work In the article: http://www.mysqlperformanceblog.com/2006/09/01/order-by-limit-performance-optimization/ He claims that you should have the index cover both the WHERE clause and the ORDER BY clause to get good performance. This is for MySql, so I don't know if it applies to H2.
