Abstract
Sort plus operations such as 'group by' and 'distinct' generally require sorting of the retrieved data before performing the sort plus operation. A method and apparatus is disclosed for executing a query specifying a sort plus operation without performing the sorting operation. To perform the sort plus operation, it is determined whether a sorted source exists that can be used to obtain the data specified in the query. If the sorted source does exist, it is then used to perform the sort plus operation.
