Analytical function are the builtin function in Oracle, so during execution it will be faster then other simple function. These function are basically used for reporting and most of the time to improve performance of your query. Oracle have lot of analytical functions for eg.: rollup, rank, dense_rank etc.

I am working on Oracle 9i and as far as I know the function "Last_Value" doesnt work in 9i. We are using the "First_Value" function with order by clause using descending order.

Select First_Value(FieldName) Over (Partition by FieldName Order by TrandDate Desc) From <TableName>.
