sql server 2008 - Converting float to varchar with correct decimal separator

Question

Hi i'm living in austria and we use the , as decimal separator.

It seems to be impossible to convert the float to varchar with the correct separator according to the language/collation setting?

Is this a bug?

set language german --makes no difference in this case
declare @f float = 4.5
select @f --output in my management studio is 4,5 
          --according to the regional os settings this is correct

select convert(varchar,@f) -- output: 4.5 not correct

one solution, but not ideal I think

select replace(convert(varchar,@f),'.',',')

Answer 1

• SSMS formats the float type based on your regional settings
• The SQL Engine language setting doesn't affect what separators are used

Correctly, you should leave numbers as numbers and format in the client.
This is what SSMS is doing for you
