Question

Which SQL statement is used to retrieve view instances?

1) CREATE
2) DELETE
3) INSERT
4) SELECT
5) UPDATE

Answer 1

The SQL statement used to retrieve view instances is the SELECT command. It is utilized to query data from the database, including data from views, which are virtual tables that represent the results of a query.

Step-by-step explanation:

To retrieve view instances in SQL, one would use the SELECT statement. This command allows you to query data from the database, which includes both tables and views. A view is a virtual table representing the result of a database query.

For example, if there is a view named 'EmployeeView' that shows certain information about employees, you would use the following SQL statement to retrieve data from it:

SELECT * FROM EmployeeView;

This SELECT command would display all the columns from 'EmployeeView'. You can also retrieve specific columns by specifying them instead of using the asterisk (*) wildcard.
