Q1: Find the SQL statement below that is equal to the following: SELECT NAME FROM CUSTOMER WHERE STATE = 'VA';

ANS:D - SELECT NAME FROM CUSTOMER WHERE STATE IN ('VA');

The IN function helps reduce the need to use multiple OR conditions.

The syntax for the IN function is:

SELECT columns
FROM tables
WHERE column1 in (value1, value2, .... value_n);

This SQL statement will return the records where column1 is value1, value2..., or value_n. The IN function can be used in any valid SQL statement - select, insert, update, or delete.
Example #1:

The following is an SQL statement that uses the IN function:

SELECT *
FROM suppliers
WHERE supplier_name in ( 'IBM', 'Hewlett Packard', 'Microsoft');

This would return all rows where the supplier_name is either IBM, Hewlett Packard, or Microsoft. Because the * is used in the select, all fields from the suppliers table would appear in the result set.
