SQL query to retrieve a numeric value and print as words

What will be the query to extract a number from a table column and print it in words? for example: -data - 72 it should be printed as Seventy-Two

There is no RDBMS that I know of that has such a function, and even if you can write it as udf or sproc, most databases have abyssal string processing. Do this in your client application.

In the same way we use in our project. There is no built-in method for this, but I have a function that you can try on your end. Hope this helps you - Of course you can customize your requirements -
