PROPERSTATEMENT function in sqlserver to proper statement like excel

I find in one of my project to use some function like proper in excel which i already find from google. But i am having bunch of record to proper even want to sepearate some words in the sentence.

e.g.
query : select properstatement('asifghanchi','asif')
output : asif ghanchi

Description : asif is word to seperate and apply proper to whole statement.

Code:

USE [DATABASE]
GO

/****** Object: UserDefinedFunction [dbo].[PROPERSTATEMENT] Script Date: 08/04/2010 11:05:22 ******/
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[PROPERSTATEMENT]') AND type in (N'FN', N'IF', N'TF', N'FS', N'FT'))
DROP FUNCTION [dbo].[PROPERSTATEMENT]
GO

USE [DATABASE]
GO

/****** Object: UserDefinedFunction [dbo].[PROPERSTATEMENT] Script Date: 08/04/2010 11:05:22 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


CREATE FUNCTION [dbo].[PROPERSTATEMENT]
(
@input varchar(8000),
@properinput varchar(8000)
)
RETURNS varchar(8000)
AS
BEGIN
IF (LEN(@properinput) = 0 OR LEN(@input) = 0)
RETURN DBO.PROPERCASE(@input)
ELSE IF (CHARINDEX(',',@properinput) = 0 AND CHARINDEX(@properinput,@input) = 0)
RETURN DBO.PROPERCASE(@input)
ELSE IF (CHARINDEX(',',@properinput) = 0 AND CHARINDEX(@properinput,@input) = 1)
RETURN DBO.PROPERCASE(@properinput) + ' ' + DBO.PROPERCASE(REPLACE(@input,@properinput,''))
ELSE IF (CHARINDEX(',',@properinput) = 0 AND CHARINDEX(@properinput,@input) > 1)
RETURN DBO.PROPERCASE(SUBSTRING(@input,1,CHARINDEX(@properinput,@input)-1)) + ' ' + DBO.PROPERCASE(@properinput) + ' ' + DBO.PROPERCASE(SUBSTRING(@input,CHARINDEX(@properinput,@input)+LEN(@properinput),LEN(@input)))
ELSE IF CHARINDEX(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1),@input) = 0
RETURN [dbo].[PROPERSTATEMENT](@input,SUBSTRING(@properinput,CHARINDEX(',',@properinput)+1,LEN(@properinput)))
ELSE IF CHARINDEX(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1),@input) = 1
RETURN DBO.PROPERCASE(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1)) + ' ' + [dbo].[PROPERSTATEMENT](REPLACE(@input,SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1),''),SUBSTRING(@properinput,CHARINDEX(',',@properinput)+1,LEN(@properinput)))
ELSE IF CHARINDEX(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1),@input) > 1
RETURN [dbo].[PROPERSTATEMENT](SUBSTRING(@input,1,CHARINDEX(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1),@input) - 1) ,SUBSTRING(@properinput,CHARINDEX(',',@properinput)+1,LEN(@properinput))) + ' ' + DBO.PROPERCASE(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1)) + ' ' + [dbo].[PROPERSTATEMENT](SUBSTRING(@input,CHARINDEX(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1),@input) + LEN(SUBSTRING(@properinput,1,CHARINDEX(',',@properinput)-1)),LEN(@input)),SUBSTRING(@properinput,CHARINDEX(',',@properinput)+1,LEN(@properinput)))
ELSE
RETURN @input
RETURN @input
END
