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
Output
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;
Output
This will produce the following output −
+--------+ | Number | +--------+ | 4 | | 7 | | 9 | | 11 | | 0 | +--------+ 5 rows in set (0.00 sec)
