Nutka1998 [239]

Answer:

SELECT COUNT (DISTICT constraint_name)

FROM apd_schema.constraint_column_usage

RUN

Explanation:

General syntax to return a catalog view of information about foreign keys.

SELECT DISTINCT PARENT_TABLE =

RIGHT(Replace(DC.constraint_name, 'fkeys_', ''),

Len(Replace(DC.constraint_name, 'fkeys_', '')) - Charindex('_', Replace(DC.constraint_name, 'fkeys_', ''))),

CHILD_TABLE = DC.table_name,

CCU.column_name,

DC.constraint_name,

DC.constraint_type

FROM apd_schema.table_constraints DC

INNER JOIN apd_schema.constraint_column_usage CCU

ON DC.constraint_name = CCU.constraint_name

WHERE DC.constraint_type LIKE '%foreign'

OR DC.constraint_type LIKE '%foreign%'

OR DC.constraint_type LIKE 'foreign%'

Check the explanation

Explanation:

// include the necessary packages

import java.io.*;

import java.util.*;

// Declare a class

public class DataReader

{

// Start the main method.

public static void main(String[] args)

{

// create the object of scanner class.

Scanner scan = new Scanner(System.in);

// Declare variables.

boolean done = false;

boolean done1 = false;

float sum = 0;

double v;

int count = 0;

// start the while loop

while (!done1)

{

// start the do while loop

do

{

// prompt the user to enter the value.

System.out.println("Value:");

// start the try block

try

{

// input number

v = scan.nextDouble();

// calculate the sum

sum = (float) (sum + v);

}

// start the catch block

catch (Exception nfe)

{

// input a character variable(\n)

String ch = scan.nextLine();

// display the statement.

System.out.println(

"Input Error. Try again.");

// count the value.

count++;

break;

}

// end do while loop

while (!done);

// Check whether the value of count

// greater than 2 or not.

if (count >= 2)

{

// display the statement on console.

System.out.println("Sum: " + sum);

done1 = true;

}

Sample Output:

Value:

12

Value:

12

Value:

ten

Input Error. Try again.

Value:

5

Value:

nine

Input Error. Try again.

Sum: 29.0
