Question

我想用一栏ts,但我想再说一栏。在MySql这样做是否有任何进展?

Answer 1

你不妨尝试:

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

试验:

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)

Answer 2

你可以做以下工作:

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

数值将低于清单。

Answer 3

SELECT * FROM your_table ORDER BY 0.1/your_field;

Answer 4

下面的询问应当做到。

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