3-6. Iterating Cursor Results Until All Rows Have Been Returned
Problem
You have created a cursor and retrieved a number of rows from the database. As a result, you want to loop through the results and do some processing on them.
Solution
Use a standard FOR loop to iterate through the records. Within each iteration of the loop, process the current record. The following code shows the use of a FOR loop to iterate through the records retrieved from the cursor and display each employee name and e-mail. Each iteration of the loop returns an employee with the job_id of 'ST_MAN', and the loop will continue to execute until the cursor has been exhausted.
