Sample Solution:
SQL Code(MySQL):
CREATE TABLE item (item_code int not null unique, item_desc varchar(255), cost int);
INSERT INTO item VALUES(101,'mother board', 2700);
INSERT INTO item VALUES(102,'RAM', 800);
INSERT INTO item VALUES(103,'key board',300);
INSERT INTO item VALUES(104,'mouse',300);
CREATE TABLE sales_info (distributor_id int, item_code int, retailer_id int, date_of_sell date, quantity int, total_cost int);
INSERT INTO sales_info VALUES(5001,101,1001,'2020-02-12',3,8100);
INSERT INTO sales_info VALUES(5001,103,1002,'2020-03-15',15,4500);
INSERT INTO sales_info VALUES(5002,101,1001,'2020-06-24',2,5400);
INSERT INTO sales_info VALUES(5001,104,1003,'2020-09-11',8,2400);
INSERT INTO sales_info VALUES(5003,101,1003,'2020-10-21',5,13500);
INSERT INTO sales_info VALUES(5003,104,1002,'2020-12-27',10,3000);

INSERT INTO sales_info VALUES(5002,103,1004,'2020-06-17',8,2400);
INSERT INTO sales_info VALUES(5003,103,1001,'2020-04-12',3,900);
SELECT item_code, item_desc
FROM item
WHERE item_code IN (
SELECT item_code
FROM sales_info
WHERE date_of_sell BETWEEN '2020-04-01' AND '2020-06-30'
