A VERY simple way to do this... JC65100

ALTER FUNCTION [dbo].[ITS_GetDifCharCount] 
(
@str1 VARCHAR(MAX)
,@str2 VARCHAR(MAX)
)
RETURNS INT
AS
BEGIN
DECLARE @result INT

SELECT @result = COUNT(*)
FROM dbo.ITS_CompareStrs(@str1,@str2 )

RETURN @result

END


ALTER FUNCTION [dbo].[ITS_CompareStrs]
(
@str1 VARCHAR(MAX)
,@str2 VARCHAR(MAX)
)
RETURNS 
@Result TABLE  (ind INT, c1 char(1), c2 char(1))
AS
BEGIN
    DECLARE @i AS INT
             ,@c1 CHAR(1)
             ,@c2 CHAR(1)

    SET @i = 1

    WHILE LEN (@str1) > @i-1  OR LEN (@str2) > @i-1   
    BEGIN

      IF LEN (@str1) > @i-1
        SET @c1 = substring(@str1, @i, 1)  

      IF LEN (@str2) > @i-1
        SET @c2 = substring(@str2, @i, 1)

      INSERT INTO @Result([ind],c1,c2)
      SELECT @i,@c1,@c2

      SELECT @i=@i+1
              ,@c1=NULL
              ,@c2=NULL

    END

    DELETE FROM @Result
    WHERE c1=c2


RETURN 
END
