Answer 1

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)
