This statement indicates one of the ways that Adaptive Server returns result rows from a table.
In the case of “Using GETSORTED,” the rows are returned in sorted order. However, not all queries that return rows in sorted order include this step. For example, order by queries whose rows are retrieved using an index with a matching sort sequence do not require “GETSORTED.”
The “Using GETSORTED” method is used when Adaptive Server must first create a temporary worktable to sort the result rows and then return them in the proper sorted order. The examples for distinct on and for order by on show the “Using GETSORTED” message.
