Order by desc except a single value in MySQL
Use ORDER BY and set DESC to order by desc. However, to get all the values except a single value, use the not equal operator.
Let us first create a table −
mysql> create table DemoTable -> ( -> Name varchar(100) -> ); Query OK, 0 rows affected (0.89 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Sam');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('John');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('Carol');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('Adam');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('David');
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 −
+-------+ | Name | +-------+ | Sam | | Chris | | John | | Carol | | Adam | | David | +-------+ 6 rows in set (0.00 sec)
Following is the query to order by desc except a single value i.e. Name “Adam” here −
mysql> select *from DemoTable ORDER BY (Name <> 'Adam') DESC,Name;
Output
This will produce the following output −
+-------+ | Name | +-------+ | Carol | | Chris | | David | | John | | Sam | | Adam | +-------+ +6 rows in set (0.00 sec)
