You can maintain the order in MySQL IN query with the help of field command. The syntax is as follows −
select *from yourTableName anyVariableName where anyVariableName.yourColumnName in(value1,value2,......N) order by field(anyVariableName.yourColumnName,value1,value2,......N);
To implement the above syntax let us create a table −
mysql> create table OrderInDemo −> ( −> Id int, −> Name varchar(100), −> Age int −> ); Query OK, 0 rows affected (1.24 sec)
Now let us insert some records in the table. The query to insert records are as follows −
mysql> insert into OrderInDemo values(90,'David',23); Query OK, 1 row affected (0.10 sec) mysql> insert into OrderInDemo values(9,'Sam',24); Query OK, 1 row affected (0.59 sec) mysql> insert into OrderInDemo values(10,'Carol',19); Query OK, 1 row affected (0.25 sec) mysql> insert into OrderInDemo values(1,'John',26); Query OK, 1 row affected (0.42 sec) mysql> insert into OrderInDemo values(3,'Johnson',25); Query OK, 1 row affected (0.18 sec) mysql> insert into OrderInDemo values(2,'Ramit',20); Query OK, 1 row affected (0.18 sec)
Display all records with the help of select statement. The query is as follows −
mysql> select *from OrderInDemo;
The following is the output −
+------+---------+------+ | Id | Name | Age | +------+---------+------+ | 90 | David | 23 | | 9 | Sam | 24 | | 10 | Carol | 19 | | 1 | John | 26 | | 3 | Johnson | 25 | | 2 | Ramit | 20 | +------+---------+------+ 6 rows in set (0.00 sec)
Implement the syntax we discussed, in the beginning, to maintain order in MySQL IN query. The query is as follows −
mysql> select *from OrderInDemo OD where OD.Id in(10,1,3) −> order by field(OD.Id,10,1,3);
The following is the output that displays the results ordered in the sequence provided in the query −
+------+---------+------+ | Id | Name | Age | +------+---------+------+ | 10 | Carol | 19 | | 1 | John | 26 | | 3 | Johnson | 25 | +------+---------+------+ 3 rows in set (0.00 sec)
