Order MySQL query by multiple ids?

MySQLMySQLi Database

For this, use ORDER BY FIELD(). Let us first create a table −

mysql> create table DemoTable(
   ClientId varchar(40),
   ClientName varchar(40)
);
Query OK, 0 rows affected (0.55 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('987_John','John');
Query OK, 1 row affected (0.33 sec)
mysql> insert into DemoTable values('1000_Sam','Sam');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable values('777_Carol','Carol');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values('2000_Bob','Bob');
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-----------+------------+
| ClientId  | ClientName |
+-----------+------------+
| 987_John  | John       |
| 1000_Sam  | Sam        |
| 777_Carol | Carol      |
| 2000_Bob  | Bob        |
+-----------+------------+
4 rows in set (0.00 sec)

Following is the query to order MySQL query by multiple ids −

mysql> select *from DemoTable
order by field(ClientId,'1000_Sam','2000_Bob','777_Carol','987_John');

This will produce the following output −

+-----------+------------+
| ClientId  | ClientName |
+-----------+------------+
| 1000_Sam  | Sam        |
| 2000_Bob  | Bob        |
| 777_Carol | Carol      |
| 987_John  | John       |
+-----------+------------+
4 rows in set (0.04 sec)
