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

Question

I want to sort by an column of ints ascending, but I want 0 to come last. Is there anyway to do this in MySql?

Answer 1

You may want to try the following:

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

Test case:

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);

Result:

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

The following query should do the trick.

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