Order by the choice of strings you want, using the FIELD() function. The syntax is as follows −
SELECT *FROM yourTableName ORDER BY FIELD(yourColumnName,’yourValue1’, ’yourValue2’,’yourValue3’,....N);
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table OrderByListOfStrings -> ( -> Id int not null auto_increment, -> CarName varchar(20), -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.68 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into OrderByListOfStrings(CarName) values('Ford'); Query OK, 1 row affected (0.18 sec) mysql> insert into OrderByListOfStrings(CarName) values('Audi'); Query OK, 1 row affected (0.17 sec) mysql> insert into OrderByListOfStrings(CarName) values('Honda'); Query OK, 1 row affected (0.13 sec) mysql> insert into OrderByListOfStrings(CarName) values('Aston Martin'); Query OK, 1 row affected (0.53 sec) mysql> insert into OrderByListOfStrings(CarName) values('Bugatti'); Query OK, 1 row affected (0.20 sec) mysql> insert into OrderByListOfStrings(CarName) values('BMW'); Query OK, 1 row affected (0.21 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from OrderByListOfStrings;
The following is the output −
+----+--------------+ | Id | CarName | +----+--------------+ | 1 | Ford | | 2 | Audi | | 3 | Honda | | 4 | Aston Martin | | 5 | Bugatti | | 6 | BMW | +----+--------------+ 6 rows in set (0.00 sec)
Here is the query to get the order by the choice of strings. Set in whatever order you want them −
mysql> select *from OrderByListOfStrings -> order by field(CarName,'Bugatti','BMW','Audi','Aston Martin','Ford','Honda');
The following is the output that rearranges string set with field() method −
+----+--------------+ | Id | CarName | +----+--------------+ | 5 | Bugatti | | 6 | BMW | | 2 | Audi | | 4 | Aston Martin | | 1 | Ford | | 3 | Honda | +----+--------------+ 6 rows in set (0.00 sec)
