Cara mendapatkan substring dengan fungsi bawaan T-sql

Manfaatkan PARSENAME ?

SELECT
   PARSENAME(REPLACE(name, ' ', '.'), 2),
   PARSENAME(REPLACE(name, ' ', '.'), 1)
FROM
    MyTable;

EDIT contoh kerja:

DECLARE @MyTable table (name varchar(25))
INSERT @MyTable 
    SELECT 'Joe Smith' 
    UNION SELECT 'Bill Jones' 
    UNION SELECT 'Billy Bob Braxton' 
    UNION SELECT 'Mark'

SELECT
   PARSENAME(REPLACE(name, ' ', '.'), 2),
   PARSENAME(REPLACE(name, ' ', '.'), 1)
FROM
    @MyTable;

Keluaran:

------ --------
Bill   Jones
Bob    Braxton
Joe    Smith
NULL   Mark
