Rename columns II
Consider the following table ecommerce_orders, which contains a list of all orders processed by an ecommerce website.
+----------+-----------+------------+--------------+-------------+-------------------+
| order_id | status | created_at | delivered_at | returned_at | ecommerce_user_id |
+----------+-----------+------------+--------------+-------------+-------------------+
| 1 | Cancelled | Sept. 2... | None | None | 1 |
| 2 | Complete | Sept. 2... | Sept. 23,... | None | 1 |
| 3 | Complete | Aug. 8t... | Aug. 12th... | None | 2 |
| ... | ... | ... | ... | ... | ... |
+----------+-----------+------------+--------------+-------------+-------------------+
Write a query that returns the order_id and status columns from this table. In your query’s result, the status column should be renamed to order_status.
EXPECTED OUTPUT
+----------+-----------------+
| order_id | order_status |
+----------+-----------------+
| 1 | Cancelled |
| 2 | Complete |
| 3 | Complete |
| ... | ... |
+----------+-----------------+
Use
SELECT col1 AS new_col_name
FROM table1
to give col1 the name new_col_name in your query's result.
SELECT
order_id,
status AS order_status
FROM ecommerce_orders
