Format a number with commas but without decimals in SQL Server 2008 R2?

Question

I am using the following to create a comma formatted number in T-SQL. How can I get rid of the decimal point and the digits after decimal. So if I get 1,112.00 after formatt

Answer 1

After some research, I found 2 possible answers to my initial question. They are listed below.

Option 1: The answer from Mitch Wheat is a possible answer. However, when one wants to format a column value within a SELECT, then we would have to create a user-defined scalar function using Mitch's T-SQL code, and call this UDF from our SQL.

-- =============================================
-- Description: Formats a number and truncates 
--              the decimal part. You can pass 
--              a number as a string or a numeric type.
-- =============================================
CREATE FUNCTION dbo.Utility_fn_FormatNumberAndTruncateDecimals
(
   @unFormattedNumber VARCHAR(100)
)
 RETURNS VARCHAR(100)
  AS
 BEGIN
   DECLARE @val VARCHAR(100)
   SET @val = convert(VARCHAR(50), cast(@unFormattedNumber AS MONEY), 1)

   RETURN (SELECT left(@val, len(@val) - 3))
 END
 GO

 --call this function using either of the SELECTS below
 SELECT dbo.Utility_fn_FormatNumberAndTruncateDecimals('233444')
 SELECT dbo.Utility_fn_FormatNumberAndTruncateDecimals(233444.345)

Option 2: We can use an inbuilt system function called 'parsename' as in T-SQL code below, to format and truncate decimals.

SELECT PARSENAME(CONVERT(VARCHAR, CAST('2334442221.345222'  AS MONEY), 1),2)
