(iii) Display the name, address, and phone of customers who have placed orders in the month of June or July.

Answer:

SELECT CName, Address, Phone FROM CUSTOMER, ORDER WHERE CUSTOMER.CID = ORDER.CID AND (Date LIKE ‘%-06-%’ OR Date LIKE ‘%-07-%’);

To display the name, address, and phone of customers who have placed orders in the month of June or July, we need to use the SELECT statement in SQL. In this case, we want to select the CName, Address and Phone columns from the CUSTOMER table.
We also need to join the CUSTOMER table with the ORDER table based on the CID column.
We also need to specify the condition that the Date column of the ORDER table contains either 06 or 07 as the month part.
We use the WHERE clause to specify these conditions.
We also use parentheses to group multiple conditions and use OR operator to combine them .
We also use LIKE operator and wildcard characters (%) to match a pattern in a string value .

So, we write:

SELECT CName, Address, Phone FROM CUSTOMER, ORDER WHERE CUSTOMER.CID = ORDER.CID AND (Date LIKE '%-06-%' OR Date LIKE '%-07-%');

Here, % represents any sequence of characters in SQL. So, Date LIKE ‘%-06-%’ means any date that has -06- as a substring.
