SELECT statement: It is used to retrieve information from the table or database . The syntax for the “SELECT” statement is given below: SELECT * FROM table_Name; SUM function: The “SUM” function is used to add the value and then return the sum of the expression in a “SELECT” statement. Syntax: SELECT SUM (exp) FROM table_Name [WHERE condition]; 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; ORDER BY Clause: SQL contains “ORDER BY” clause in order to sort rows. The values get sorted in ascending as well as descending order. The keyword used to sort values in ascending order is “ASC” and for descending order is “DESC”.

SELECT statement: It is used to retrieve information from the table or database. The syntax for the “SELECT” statement is given below:

SELECT * FROM table_Name;

SUM function: The “SUM” function is used to add the value and then return the sum of the expression in a “SELECT” statement.

Syntax:

SELECT SUM (exp) FROM table_Name [WHERE condition];

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;

ORDER BY Clause:

SQL contains “ORDER BY” clause in order to sort rows. The values get sorted in ascending as well as descending order. The keyword used to sort values in ascending order is “ASC” and for descending order is “DESC”. By default, it sorts values by ascending order.

Syntax:

SELECT column_Name1, column_Name2 FROM table_Name ORDER BY column_Name2;

7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)
