SQL Server 2008: how to format the output as a currency

Question

I have a query string which returns a value that has several decimal places. I want to format this to a currency $123.45.

Here is the query:

SELECT         


        

Answer 1

Here's a suggestion of the syntax to use to future-proof the search query.

select format(123.56789,'C2','en-US')  --$123.57 ;
select format(123.56789,'C3','en-US') --$123.568;
select format(123.56789,'C0','en-US') --$124
