Answer Posted / yogish naik
we can observe that the aggregate functions return only one
row per group whereas analytic functions keeps all the rows
in the group. Using the aggregate functions, the select
clause contains only the columns specified in group by
clause and aggregate functions whereas in analytic functions
you can specify all the columns in the table.
The PARTITION BY clause is similar to GROUP By clause, it
specifies the window of rows that the analytic funciton
should operate on.
