Ordered analytical functions use values from multiple rows to compute a new value.

The result of an ordered analytical function is handled the same as any other SQL expression. It can be a result column or part of a more complex arithmetic expression within its SELECT.

Each of the ordered analytical functions permit you to specify the sort ordering column or columns on which to sort the rows retrieved by the SELECT statement. The sort order and any other input parameters to the functions are specified the same as arguments to other SQL functions and can be any normal SQL expression.
