MySQL - SELECT … WHERE id IN (..) order with particular column?
You can SELECT ….WHERE id IN(..) using field() function to order with any column. The syntax is as follows −
SELECT *FROM yourTableName WHERE yourColumnName IN(‘value1’,’value2’,.......N) ORDER BY FIELD(yourColumnName,value1’,’value2’,.......N);
To understand the above syntax, let us create a table −
mysql> create table SelectOrderbyField -> ( -> Id int NOT NULL AUTO_INCREMENT, -> Name varchar(30), -> Age int, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.62 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into SelectOrderbyField(Name,Age) values('John',23);
Query OK, 1 row affected (0.13 sec)
mysql> insert into SelectOrderbyField(Name,Age) values('Carol',25);
Query OK, 1 row affected (0.16 sec)
mysql> insert into SelectOrderbyField(Name,Age) values('Bob',21);
Query OK, 1 row affected (0.15 sec)
mysql> insert into SelectOrderbyField(Name,Age) values('Mike',28);
Query OK, 1 row affected (0.17 sec)
mysql> insert into SelectOrderbyField(Name,Age) values('Sam',26);
Query OK, 1 row affected (0.12 sec)
mysql> insert into SelectOrderbyField(Name,Age) values('David',23);
Query OK, 1 row affected (0.19 sec)Display all records from the table using select statement. The query is as follows −
mysql> select *from SelectOrderbyField;
The following is the output −
+----+-------+------+ | Id | Name | Age | +----+-------+------+ | 1 | John | 23 | | 2 | Carol | 25 | | 3 | Bob | 21 | | 4 | Mike | 28 | | 5 | Sam | 26 | | 6 | David | 23 | +----+-------+------+ 6 rows in set (0.00 sec)
Here are the queries to select ...where id in(..) using order by field() function.
Order with ID column
The query is as follows −
mysql> select *from SelectOrderbyField where Id IN(5,1,3,2,6,4) -> order by field(Id,5,1,3,2,6,4);
The following is the output −
+----+-------+------+ | Id | Name | Age | +----+-------+------+ | 5 | Sam | 26 | | 1 | John | 23 | | 3 | Bob | 21 | | 2 | Carol | 25 | | 6 | David | 23 | | 4 | Mike | 28 | +----+-------+------+ 6 rows in set (0.00 sec)
Order with Name column
You can correctly order on the basis of Name column. The query is as follows −
mysql> select *from SelectOrderbyField where Name IN('Sam','John','Bob','Carol','David','Mike')
-> order by field(Name,'Sam','John','Bob','Carol','David','Mike');The following is the output −
+----+-------+------+ | Id | Name | Age | +----+-------+------+ | 5 | Sam | 26 | | 1 | John | 23 | | 3 | Bob | 21 | | 2 | Carol | 25 | | 6 | David | 23 | | 4 | Mike | 28 | +----+-------+------+ 6 rows in set (0.03 sec)
