MySQL Questions?

Margarita [4]

Answer:

The Statement for selecting values from the table in SQL is given below,

SELECT vendor_name, vendor_contact_last_name, vendor_contact_first_name FROM Vendors;

Explanation:

SQL stands for Structured query language which is used to insert, update, delete and modify the value in a table.

There are five types of SQL-

1. Data definition language

2. Data manipulation language

3. Data control language

4. Transaction Control Language

5. Data Query Language

The SELECT statement comes under DDL which is used to select and display values from a table.

We can use select statement in two ways-

1. SELECT column_name1, column_name2 ........column_nameN FROM Table_name;

2. SELECT * FROM tablename; ( This is used to select all values from the table name)

We can also give conditions using WHERE clause while selecting values.

Luda [366]

Answer:

The program in Python is as follows:

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

num = input("Decimal: ")

BCDValue = ""

valid = True

for i in range(len(num)):

if num[i].isdigit():

if(int(num[i])>= 0 and int(num[i])<8):

BCDValue += BCD[i]+" "

else:

valid = False

break;

else:

valid = False

break;

if(valid):

print(BCDValue)

else:

print("Invalid")

Explanation:

This initializes the BCD corresponding value of the decimal number to a list

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

This gets input for a decimal number

num = input("Decimal: ")

This initializes the required output (i.e. BCD value) to an empty string

BCDValue = ""

This initializes valid input to True (Boolean)

valid = True

This iterates through the input string

for i in range(len(num)):

This checks if each character of the string is a number

if num[i].isdigit():

If yes, it checks if the number ranges from 0 to 7 (inclusive)

if(int(num[i])>= 0 and int(num[i])<8):

If yes, the corresponding BCD value is calculated

BCDValue += BCD[i]+" "

else:

If otherwise, then the input string is invalid and the loop is exited

valid = False

break;

If otherwise, then the input string is invalid and the loop is exited

else:

valid = False

break;

If valid is True, then the BCD value is printed

if(valid):

print(BCDValue)

If otherwise, it prints Invalid

else:

print("Invalid")
