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.
