SQL取外国人名字的缩写（如Michael Joseph Jackson写成M* J* Jackson）

CREATE FUNCTION dbo.fnGetForeignerShotName ( @str NVARCHAR(4000) )
RETURNS NVARCHAR(2000)
AS
BEGIN
    DECLARE @retval NVARCHAR(2000);
    SET @str=RTRIM(LTRIM(@str));
    SET @retval=''
	
    WHILE CHARINDEX(' ',@str,1)>0 BEGIN
        SET @retval+=LEFT(@str,1)+'* ';		
		SET @str= LTRIM(RIGHT(@str,LEN(@str)-CHARINDEX(' ',@str,1)));
    END
	set @retval+=@str;
	RETURN @retval;
END
GO



SELECT dbo.fnGetForeignerShotName('Michael Joseph Jackson');
