14-7. Creating a Sortable Web Report
Problem
You need a report that displays data that is sorted by a field the user selects.
Solution
Create a package that prompts the user for a sort field, then generates the sorted output using the sort field parameter in the ORDER BY section of the SELECT statement. In this example the user is prompted to select a sort option on the EMPLOYEEs table. The options are to sort by last name, hire date, salary, or employee ID.
