To be consistent, we will use the same example table used in the Top-N Queries article. You provide two parameters: the offset number, and the count. This can be especially useful when querying very large tables in cases where the user is only interested in the first so many rows from the table. So when you have two parameters, the first is the starting row, the second is the number of rows.

Top-N queries provide a method for limiting the number of rows returned from ordered sets of data. They are extremely useful when you want to return the top or bottom N number of rows from a set or when you are paging through data. This article presents several methods to implement Top-N queries. In some cases, you will be required to use the SQL GROUP BY clause with the SQL MAX function.


For example, you could also use the SQL MAX function to return the name of each department and the maximum salary in the department.
