Program Plan Intro

Display values from table:

The contents from the table can be viewed by using “SELECT” statement which comes under Data Manipulation Language (DML).

The Syntax to view the contents using asterisk (*) is as follows:

SELECT * FROM table_Name;

Selective columns can also be retrieved by replacing all the column(s) names in place of the asterisk symbol.

WHERE Statement:

“WHERE” statement is used limit the number of rows.

For example: Consider a table “FTable” that has two columns named “FruitName” and “Color”. “WHERE” clause is used when there is a need to display the entire FruitName whose color is Red.

SELECT * FROM FTable WHERE color = 'red';

When the above statement is executed, red colored fruits get displayed.

LIKE operator:

“LIKE” operator is used to get set of values which matches the set of characters. The “LIKE” operator uses “%” sign and it uses underscore (_) which is used to represent the characters.

Syntax:

SELECT * FROM table_Name WHERE column_Name LIKE pattern;

You are working with a database table that contains customer data. The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country.  You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.
We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure.  Alice's public key (n,public_key) is (247,7). A code breaker manages to factories  247 = 13 x 19  Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.
Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
