In SQL, it is not mandatory for an alias to have a different name from the original column name. You can use the same name for an alias as the original column. However, it is generally advisable to use a different name or modify the alias for clarity, especially when working with multiple columns in a query. This practice helps avoid confusion and enhances readability of the code. For instance, if you have a column called `age`, you can create an alias as follows:

```sql
SELECT age AS age FROM users;
```

In this case, the alias `age` is the same as the original column name, and the query will still work correctly. However, it's always a good idea to use distinct names for clarity when necessary.
