You can show the null values which represent the concept of missing or inapplicable information, with other values for better data representation.
Suppose we have a table as below:
| Name | Country |
| John | India |
| Jane | Australia |
| Tim | [NULL] |
So if you query from the database the null result will show the blank result.
SELECT name,
IF(country IS NULL,"No Country",country) country
FROM users; | Name | Country |
| John | India |
| Jane | Australia |
| Tim | No Country |
MySQL also handles the null values directly using IFNULL function.
SELECT name,
IFNULL(country,"No Country") country
