Last update on December 20 2024 11:56:21 (UTC/GMT +8 hours)

From the following table, write a SQL query to select orders between 500 and 4000 (begin and end values are included). Exclude orders amount 948.50 and 1983.43. Return ord_no, purch_amt, ord_date, customer_id, and salesman_id.

Sample table: orders

ord_no      purch_amt   ord_date    customer_id  salesman_id
----------  ----------  ----------  -----------  -----------
70001       150.5       2012-10-05  3005         5002
70009       270.65      2012-09-10  3001         5005
70002       65.26       2012-10-05  3002         5001
70004       110.5       2012-08-17  3009         5003
70007       948.5       2012-09-10  3005         5002
70005       2400.6      2012-07-27  3007         5001
70008       5760        2012-09-10  3002         5001
70010       1983.43     2012-10-10  3004         5006
70003       2480.4      2012-10-10  3009         5003
70012       250.45      2012-06-27  3008         5002
70011       75.29       2012-08-17  3003         5007
70013       3045.6      2012-04-25  3002         5001

Sample Solution:

-- This query selects all columns from the 'orders' table.
SELECT *
-- Specifies the table from which to retrieve the data (in this case, 'orders').
FROM orders
-- Filters the rows to only include those where the 'purch_amt' column is between 500 and 4000 (inclusive)
-- and the 'purch_amt' column is not equal to 948.50 or 1983.43.
WHERE (purch_amt BETWEEN 500 AND 4000) AND NOT purch_amt IN (948.50, 1983.43);

Output of the Query:

ord_no	purch_amt	ord_date	customer_id	salesman_id
70005	2400.60		2012-07-27	3007		5001
70003	2480.40		2012-10-10	3009		5003
70013	3045.60		2012-04-25	3002		5001

Code Explanation:

The said SQL query selects all columns (*) from the 'orders' table where the value of the "purch_amt" column is between 500 and 4000, and also excludes any rows where the value of "purch_amt" is 948.50 or 1983.43.
