Always show decimal places in SQL?

Question

I\'m working on a query which returns numeric values (currency). Some of the values are whole numbers and are being displayed as 3, 5, 2 etc whilst other numbers are coming

Answer 1

The to_char fixes the decimal issue but you have to be certain about the length. If it is longer than the format provided, it will show the number as ####. If the number is shorter, then it will leave spaces before the number. e.g

to_char(123.45),'99.00') will show ####

and

to_char(123.45),'999999.00') will show ' 123.45'.

So, if you have to export the results to CSV or Excel, these numbers will be treated as string.

So, I have not found any solution to it.
