+------------+--------------+-----------+
| COUNTRY_ID | COUNTRY_NAME | REGION_ID |

| C0001      | India        |      1001 |
| C0002      | USA          |      1007 |
| C0003      | UK           |      1003 |

Sample Solution:

-- Inserting records into the 'countries' table from the 'country_new' table
INSERT INTO countries
-- Selecting all records from the 'country_new' table
SELECT * FROM country_new;

Let execute the above code in MySQL command prompt.

Here is the structure of the table:

mysql> SELECT * FROM country_new;
+------------+--------------+-----------+
| COUNTRY_ID | COUNTRY_NAME | REGION_ID |
+------------+--------------+-----------+
| C0001      | India        |      1001 |
| C0002      | USA          |      1007 |
| C0003      | UK           |      1003 |
+------------+--------------+-----------+
3 rows in set (0.00 sec)

Explanation:

The above MySQL code inserts records into the 'countries' table by selecting all records from the existing 'country_new' table. It essentially copies the data from one table to another.
