I want to print for example: (There should be a empty line after each smiley face, and show the data for the remaining 4 people after) Ravi: The average for quiz 1 is: 38.8055555556 You did 22.1944444444 points higher than the average! :) The average for quiz 2 is: 55.1891891892 You did 9.81081081081 points higher than the average! :) The average for quiz 3 is: 40.0606060606 You did 11.9393939394 points higher than the average! :) The average for quiz 4 is: 65.3548387097 You did 3.35483870968 points lower than the average! :(

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
