SQL ORDER BY查詢

Question

我想讓我的表rcarddet由「SDNO」（非主鍵）按升序排列，但「0」除外。因此，它應該變成是這樣的：

1 
1 
2 
. 
. 
10 
0 
0 

我的查詢現在是：

SELECT * 
    FROM `rcarddet` 
WHERE `RDATE` = '2011-05-25' 
    AND `RCNO` = '1' 
    AND `PLACE` = 'H' 
    AND `SDNO` != 0 
ORDER BY `rcarddet`.`SDNO` ASC; 

Answer 1

SELECT * 
    FROM `rcarddet` 
WHERE `RDATE` = '2011-05-25' 
    AND `RCNO` = '1' 
    AND `PLACE` = 'H' 
ORDER BY 
    `SDNO` = 0, 
    `SDNO`; 

Answer 2

SELECT * FROM rcarddet 
    WHERE RDATE = '2011-05-25' and RCNO = '1'and PLACE = 'H' 
ORDER BY CASE 
      WHEN rcarddet.SDNO = 0 THEN [max_number_for_the_type_of_SDNO] 
      ELSE rcarddet.SDNO 
     END ASC
