How to place number 0 from a column at the end maintaining the ascending search order in MySQL?
Let us first create a table −
mysql> create table DemoTable
-> (
-> Number int
-> );
Query OK, 0 rows affected (0.58 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(9);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values(4);
Query OK, 1 row affected (0.31 sec)
mysql> insert into DemoTable values(0);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values(7);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values(11);
Query OK, 1 row affected (0.12 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable
This will produce the following output −
+--------+
| Number |
+--------+
| 9 |
| 4 |
| 0 |
| 7 |
| 11 |
+--------+
5 rows in set (0.00 sec)
Following is the query to use ORDER BY and place 0's at the end maintaining the ascending search order −
mysql> select *from DemoTable order by Number=0,Number;
This will produce the following output −
+--------+
| Number |
+--------+
| 4 |
| 7 |
| 9 |
| 11 |
| 0 |
+--------+
5 rows in set (0.00 sec)
