Problem with title case function

Hi i'm trying to make a function that will title case strings, and also deal with capitalising surnames that have Mc's in them properly, ie McIntosh.

I've tried altering a function i found on the internet to have a case statement within it and it errors, when I use the case outside it works fine... is there an issue with my construction?
BEGIN
 
DECLARE @Index          INT
DECLARE @Char           CHAR(1)
DECLARE @PrevChar       CHAR(1)
DECLARE @OutputString   VARCHAR(255)
 
SET @OutputString = LOWER(@InputString)
SET @Index = 1
 
WHILE @Index <= LEN(@InputString)
BEGIN
    SET @Char     = SUBSTRING(@InputString, @Index, 1)
    SET @PrevChar = CASE WHEN @Index = 1 THEN ' '
                         ELSE SUBSTRING(@InputString, @Index - 1, 1)
                    END
 
    IF @PrevChar IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&', '''', '(')
    BEGIN
        IF @PrevChar != '''' OR UPPER(@Char) != 'S'
            SET @OutputString = STUFF(@OutputString, @Index, 1, UPPER(@Char))
    END
 
    SET @Index = @Index + 1
 
END
	CASE
		WHEN @OutputString LIKE 'Mc%'
		THEN ('Mc'+ UPPER(SUBSTRING(@OutputString,3,1))+(RIGHT(@OutputString, LEN(@OutputString)-3)))
	END
	
RETURN @OutputString
 
END
GO

here you go....

BEGIN
Declare @InputString varchar(255)
set @InputString='mccan' 
DECLARE @Index          INT
DECLARE @Char           CHAR(1)
DECLARE @PrevChar       CHAR(1)
DECLARE @OutputString   VARCHAR(255)
 
SET @OutputString = LOWER(@InputString)
SET @Index = 1
 
WHILE @Index <= LEN(@InputString)
BEGIN
    SET @Char     = SUBSTRING(@InputString, @Index, 1)
    SET @PrevChar = CASE WHEN @Index = 1 THEN ' '
                         ELSE SUBSTRING(@InputString, @Index - 1, 1)
                    END
 
    IF @PrevChar IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&', '''', '(')
    BEGIN
        IF @PrevChar != '''' OR UPPER(@Char) != 'S'
            SET @OutputString = STUFF(@OutputString, @Index, 1, UPPER(@Char))
    END
 
    SET @Index = @Index + 1
 
END
 
if @OutputString LIKE 'Mc%'
begin
	set @OutputString=('Mc'+ UPPER(SUBSTRING(@OutputString,3,1))+(RIGHT(@OutputString, LEN(@OutputString)-3)))
end
 
        
print @OutputString
 
END

and if you want to do it with CASE only, no IF than have a look:




BEGIN
Declare @InputString varchar(255)
set @InputString='RITESH' 
DECLARE @Index          INT
DECLARE @Char           CHAR(1)
DECLARE @PrevChar       CHAR(1)
DECLARE @OutputString   VARCHAR(255)
 
SET @OutputString = LOWER(@InputString)
SET @Index = 1
 
WHILE @Index <= LEN(@InputString)
BEGIN
    SET @Char     = SUBSTRING(@InputString, @Index, 1)
    SET @PrevChar = CASE WHEN @Index = 1 THEN ' '
                         ELSE SUBSTRING(@InputString, @Index - 1, 1)
                    END
 
    IF @PrevChar IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&', '''', '(')
    BEGIN
        IF @PrevChar != '''' OR UPPER(@Char) != 'S'
            SET @OutputString = STUFF(@OutputString, @Index, 1, UPPER(@Char))
    END
 
    SET @Index = @Index + 1
 
END
 
 
   SELECT @OutputString = CASE
                WHEN @OutputString LIKE 'Mc%'
					THEN ('Mc'+ UPPER(SUBSTRING(@OutputString,3,1))+(RIGHT(@OutputString, LEN(@OutputString)-3)))
                ELSE
					@OutputString
        END
 
        
print @OutputString
 
END
