SYMPTOMS

When you run a query that contains a UNION ALL operator, a TOP clause, and an ORDER BY clause to retrieve data from a SQL Server database, you may notice that the data that is returned in the result is not consistent. The result you receive when the query is run the first time differs from the result you receive in successive runs of the same query.

You may notice similar behavior even after you run the DBCC DROPCLEANBUFFERS Transact-SQL command to clean the buffer.
