試試這個

SELECT B.VID, 
    B.BRND, 
    WMSYS.WM_CONCAT(A.DESCP) PARTS 
FROM 
    (SELECT 001 prtno,'Brake' Descp FROM dual 
    UNION ALL 
    SELECT 002 prtno,'Clutch' Descp FROM dual 
    UNION ALL 
    SELECT 003 prtno,'Alternator' Descp FROM dual 
)a, 
    (SELECT 42 VID,'Honda' Brnd,001 prt_no FROM dual 
    UNION ALL 
    SELECT 34 VID,'Toyota' Brnd,002 prt_no FROM dual 
    UNION ALL 
    SELECT 42 VID,'Honda' Brnd,003 prt_no FROM dual 
    UNION ALL 
    SELECT 34 VID,'Toyota' Brnd,001 prt_no FROM dual 
)b 
WHERE A.PRTNO = B.PRT_NO GROUP BY B.VID, 
    B.BRND;
