Order by last 3 chars in MySQL?
You can use ORDER BY RIGHT() function to order by last 3 chars in MySQL. The syntax is as follows −
SELECT *FROM yourTableName ORDER BY RIGHT(yourColumnName,3) yourSortingOrder;
Just replace the ‘yourSortingOrder’ to ASC or DESC to set the ascending or descending order respectively.
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table OrderByLast3Chars -> ( -> EmployeeId int NOT NULL AUTO_INCREMENT, -> EmployeeName varchar(20), -> EmployeeAge int, -> PRIMARY KEY(EmployeeId) -> ); Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into OrderByLast3Chars(EmployeeName,EmployeeAge) values('Carol_901',24);
Query OK, 1 row affected (0.14 sec)
mysql> insert into OrderByLast3Chars(EmployeeName,EmployeeAge) values('Bob_101',21);
Query OK, 1 row affected (0.19 sec)
mysql> insert into OrderByLast3Chars(EmployeeName,EmployeeAge) values('Sam_107',22);
Query OK, 1 row affected (0.20 sec)
mysql> insert into OrderByLast3Chars(EmployeeName,EmployeeAge) values('Mile_677',26);
Query OK, 1 row affected (0.19 sec)
mysql> insert into OrderByLast3Chars(EmployeeName,EmployeeAge) values('John_978',27);
Query OK, 1 row affected (0.75 sec)
mysql> insert into OrderByLast3Chars(EmployeeName,EmployeeAge) values('David_876',29);
Query OK, 1 row affected (0.28 sec)Display all records from the table using select statement. The query is as follows −
mysql> select *from OrderByLast3Chars;
The following is the output −
+------------+--------------+-------------+ | EmployeeId | EmployeeName | EmployeeAge | +------------+--------------+-------------+ | 1 | Carol_901 | 24 | | 2 | Bob_101 | 21 | | 3 | Sam_107 | 22 | | 4 | Mile_677 | 26 | | 5 | John_978 | 27 | | 6 | David_876 | 29 | +------------+--------------+-------------+ 6 rows in set (0.00 sec)
Here is the query to order by last 3 chars.
Case 1 − Get the result in ascending order.
The query is as follows −
mysql> select *from OrderByLast3Chars -> order by RIGHT(EmployeeName,3) asc;
The following is the output −
+------------+--------------+-------------+ | EmployeeId | EmployeeName | EmployeeAge | +------------+--------------+-------------+ | 1 | Carol_901 | 24 | | 2 | Bob_101 | 21 | | 3 | Sam_107 | 22 | | 4 | Mile_677 | 26 | | 5 | John_978 | 27 | | 6 | David_876 | 29 | +------------+--------------+-------------+ 6 rows in set (0.00 sec)
Case 2 − Get the result in descending order. The query is as follows −
mysql> select *from OrderByLast3Chars -> order by RIGHT(EmployeeName,3) desc;
The following is the output −
+------------+--------------+-------------+ | EmployeeId | EmployeeName | EmployeeAge | +------------+--------------+-------------+ | 5 | John_978 | 27 | | 1 | Carol_901 | 24 | | 6 | David_876 | 29 | | 4 | Mile_677 | 26 | | 3 | Sam_107 | 22 | | 2 | Bob_101 | 21 | +------------+--------------+-------------+ 6 rows in set (0.00 sec)
