Show comma instead of point as decimal separator

Question

I just want to get the right number format here in germany, so i need to show commas as decimal separator instead of points. But this...

DECLARE @euros money         


        

Answer 1

You can first replace thousand separator comma(,) to a Zero length string (''), and then you can replace Decimal('.') to comma(',') in the same select statement.

Answer 2

To provide the appropriate culture info, in SQL 2012 there is the FORMAT() function. Here's an example:

declare @f float = 123456.789;

select
  [raw]      = str(@f,20,3)
 ,[standard] = cast(format(@f, 'N', 'en-US') as varchar(20))
 ,[European] = cast(format(@f, 'N', 'de-de') as varchar(20))

returns

raw                  |standard   |European   |
---------------------|-----------|-----------|
          123456.789 |123,456.79 |123.456,79 |

You can also specify in the second parameter a custom format string with the same rules as for .NET.

Answer 3

DECLARE @euros money
SET @euros = 1025040.2365
SELECT REPLACE(CONVERT(varchar(30), @euros, 0), '.', ',')

should do it (at least to get 1025040,24)

Answer 4

Well, as far as I know, there are no culture-specific options for convert available.

So you can do it using replaces (yes, it looks a bit ugly...)

select 
    replace(replace(replace(convert(varchar(30), @euros, 1), ',', '|'), '.', ','), '|', '.')

Idea: first change comma to something, then change dot to comma, and then "something" back to dot.

Answer 5

You could use replace something like this:

DECLARE @euros money 
SET @euros = 1025040.2365

SELECT REPLACE(REPLACE(CONVERT(varchar(30), @euros, 1),',',''),'.',',');
