How we can use order by Query with a database table without using the Column name

Using ORDER BY without specifying a column name can be ambiguous because it's typically used to sort the data based on certain columns in a database table. However, there might be scenarios where you want to order by a specific position of the column in the table or a computed value.

One approach could involve using the column index in some databases. For instance, in MySQL, you can refer to columns by their positions:

SELECT * FROM your_table
ORDER BY 1; -- Orders the result set by the first column

However, relying on column positions can be risky as changes to the table structure might affect the ordering unexpectedly.

Another method might involve using expressions or functions to generate a derived column to sort:

SELECT * FROM your_table
ORDER BY (some_column + 10); -- Orders the result set by a computed value based on 'some_column'

This example demonstrates sorting based on the sum of a column (some_column) and a constant value (10). You can use various other functions or calculations to create a custom sorting logic.

Remember, while these methods might technically allow you to sort without explicitly specifying column names, they are not standard practices and might lead to confusion and maintenance issues. It's generally advisable to use clear and explicit column names in ORDER BY clauses for better code readability and maintainability.
