I want to sort by an column of ints ascending, but I want 0 t开发者_JS百科o come last. Is there anyway to do this in MySql?
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)
You can do the following:
SELECT value, IF (value = 0, NULL, value) as sort_order
FROM table
ORDER BY sort_order DESC
Null values will be down of the list.
SELECT * FROM your_table ORDER BY 0.1/your_field;
The following query should do the trick.
(SELECT * FROM table WHERE num!=0 ORDER BY num) UNION (SELECT * FROM table WHERE num=0)
