Write an ALTER TABLE statement that adds two new columns to the Products table: one column for product price that provides for t

matrenka [14]

Answer:

ALTER TABLE Products

ADD Products_price float(5,2) DEFAULT 9.99,

ADD Adding_time datetime;

Explanation:

So at first we need to use ALTER TABLE statement, when we use this statement we also need to provide the table name. In this case, i assume it is 'Products'.

Then, as per question, we need to add two columns.

The first one is 'product_price' and it contains decimal points. So, we need to use ADD statement and give a column name like 'Prodcuts_price' and its datatype 'float' because it contains decimal or floating points. so, for 3 digits on the left and 2 digits on the right, it makes a total of 5 digits. So, we need to declare it like this. (5,2) it means a total of 5 digits and 2 after the decimal point. after that, we need to set our Default value using the DEFALUT statement. so DEFAULT 9.99. it will set the default value to 9.99 for existing products.

And for our next column, we give its a name like 'Adding_time' then it's datatype 'datetime' because it will contain date and times.

What is a conditional statement? What is another name for conditional statement? Give 2 examples of conditional statements?

vlada-n [284]

Answer:

A conditional statement instructs a system to do action based on whether a condition is true or false. This is frequently expressed as an if-then or if-then-else expression. A conditional statement is applied to predicate choices on circumstances. When there is no condition around the instructions, they run sequentially. If you add a condition to a block of statements, the execution flow may alter depend on the outcome of the condition. It is also known as a one-way selection statement because we utilize the if condition, provide the argument, and if the argument is passed, the relevant function is performed; else, nothing happens.

Examples of conditional statements:

1) int time = 20;

if (time < 16) {

System.out.println("Have a good day.");

} else {

System.out.println(" Enjoy your evening.");

}

2) using namespace Conditional;

static void Main(string[] args)

{

// This method determines what a user should do for the day based on the weather condition

public void Weather(string myWeather)

{

// 1st condition

if (myWeather == "Sun")

{

// Decision

Console.WriteLine("Go to the beach");

}

// 2nd condition

else if (myWeather == "Rain")

{

Console.WriteLine("Go to the library")

}

// 3rd condition

else if (myWeather == "Cloudy")

{

Console.WriteLine("Go to the park")

}

else

{

//otherwise

Console.WriteLine("Rest at home")

}

}
