Reorder integer except for value 0 with MySQL?
To reorder integer except for value 0, use the below syntax −
select *from yourTableName order by yourColumnName=0 ,yourColumnName;
Let us first create a table −
mysql> create table reorderIntegerExcept0 -> ( -> value int -> ); Query OK, 0 rows affected (0.70 sec)
Following is the query to insert records in the table using insert command −
mysql> insert into reorderIntegerExcept0 values(90); Query OK, 1 row affected (0.17 sec) mysql> insert into reorderIntegerExcept0 values(10); Query OK, 1 row affected (0.21 sec) mysql> insert into reorderIntegerExcept0 values(0); Query OK, 1 row affected (0.18 sec) mysql> insert into reorderIntegerExcept0 values(40); Query OK, 1 row affected (0.18 sec) mysql> insert into reorderIntegerExcept0 values(0); Query OK, 1 row affected (0.09 sec) mysql> insert into reorderIntegerExcept0 values(50); Query OK, 1 row affected (0.17 sec) mysql> insert into reorderIntegerExcept0 values(80); Query OK, 1 row affected (0.13 sec) mysql> insert into reorderIntegerExcept0 values(0); Query OK, 1 row affected (0.10 sec) mysql> insert into reorderIntegerExcept0 values(300); Query OK, 1 row affected (0.20 sec)
Following is the query to display all records from the table using select statement −
mysql> select * from reorderIntegerExcept0;
This will produce the following output −
+-------+ | value | +-------+ | 90 | | 10 | | 0 | | 40 | | 0 | | 50 | | 80 | | 0 | | 300 | +-------+ 9 rows in set (0.00 sec)
Following is the query to reorder integer except for value 0 −
mysql> select * from reorderIntegerExcept0 order by value =0 ,value;
This will produce the following output −
+-------+ | value | +-------+ | 10 | | 40 | | 50 | | 80 | | 90 | | 300 | | 0 | | 0 | | 0 | +-------+ 9 rows in set (0.00 sec)
If you want it in descending order for integers except 0, use the below query −
mysql> select * from reorderIntegerExcept0 order by value =0,value DESC;
This will produce the following output −
+-------+ | value | +-------+ | 300 | | 90 | | 80 | | 50 | | 40 | | 10 | | 0 | | 0 | | 0 | +-------+ 9 rows in set (0.00 sec)
