----------  ----------  ----------  -----------  -----------
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:

-- Creating a VIEW named 'dateord' with columns 'ord_date' and 'odcount'
CREATE VIEW dateord(ord_date, odcount)

-- Selecting distinct order dates and counting the number of orders for each date
-- Using the 'orders' table and grouping by 'ord_date'
AS SELECT ord_date, COUNT (*)
FROM orders 
GROUP BY ord_date;

output:

sqlpractice=# SELECT *
sqlpractice-# FROM dateord;
  ord_date  | odcount
------------+---------
 2012-10-05 |       2
 2012-08-17 |       3
 2012-07-27 |       1
 2012-09-22 |       1
 2012-09-10 |       3
 2012-10-10 |       2
 2012-06-27 |       1
 2012-04-25 |       1
(8 rows)

Code Explanation:

The provided statement in SQL creates a view named dateord, which returns the count of orders placed on each unique order date.
The COUNT function have used to return the total number of orders on each unique order date.
Then groups the results by the ord_date column and returns the count of orders for each unique order date.
