Using MySql, can I sort a column but have 0 come last?

您可能想尝试以下方法:

SELECT * FROM your_table ORDER BY your_field = 0, your_field;

测试用例:

CREATE TABLE list (a int);

INSERT INTO list VALUES (0);
INSERT INTO list VALUES (0);
INSERT INTO list VALUES (0);
INSERT INTO list VALUES (1);
INSERT INTO list VALUES (2);
INSERT INTO list VALUES (3);
INSERT INTO list VALUES (4);
INSERT INTO list VALUES (5);

结果:

SELECT * FROM list ORDER BY a = 0, a;

+------+
| a    |
+------+
|    1 |
|    2 |
|    3 |
|    4 |
|    5 |
|    0 |
|    0 |
|    0 |
+------+
8 rows in set (0.00 sec)

你可以做到以下几点:

SELECT value, IF (value = 0, NULL, value) as sort_order
FROM table
ORDER BY sort_order DESC

空值将在列表的下方。

下面的查询应该能起到作用。

(SELECT * FROM table WHERE num!=0 ORDER BY num) UNION (SELECT * FROM table WHERE num=0)
