Question

Chapter 7, Problem 35P

Program Plan Intro

“GROUP BY” Clause:

The GROUPBY clause is used to group the result of a SELECT statement done on a table where the tuple values are similar for more than one column.

Syntax:

SELECT expression1, expression2, expression_n, aggregate_function (expression)FROM table_name WHERE conditions GROUP BY expression1, expression2, expression_n;

Aggregate Functions:

SQL(Structured Query Language) has some built-in functions and they are called as aggregate functions. SQL contains five built-in functions. They are:

SUM – This function is used to add values from the particular column.

Syntax: SELECT SUM(column_Name) FROM table_Name;

COUNT – This is used to count the number of rows for the particular column.

Syntax: SELECT COUNT(column_Name) FROM table_Name;

MAX – This function is used to get the maximum value from the column.

Syntax: SELECT MAX(column_Name) FROM table_Name;

MIN – This function is used to get the minimum value from the column.

Syntax: SELECT MIN(column_Name) FROM table_Name;

AVG – This function is used to get the average of all the values from the column.

Syntax: SELECT AVG(column_Name) FROM table_Name;

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
