Get records in a certain order using MySQL?
You can use ORDER BY IF() to get records in a certain order. Let us first create a table:
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, FirstName varchar(20), Branch varchar(20) ); Query OK, 0 rows affected (1.96 sec)
Following is the query to insert some records in the table using insert command:
mysql> insert into DemoTable(FirstName,Branch) values('John','CS');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable(FirstName,Branch) values('Carol','ME');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable(FirstName,Branch) values('David','ME');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable(FirstName,Branch) values('Bob','CE');
Query OK, 1 row affected (0.35 sec)
mysql> insert into DemoTable(FirstName,Branch) values('Robert','EE');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable(FirstName,Branch) values('Chris','EEE');
Query OK, 1 row affected (0.27 sec)
mysql> insert into DemoTable(FirstName,Branch) values('James','ME');
Query OK, 1 row affected (0.56 sec)Following is the query to display records from the table using select command:
mysql> select *from DemoTable;
This will produce the following output:
+----+-----------+--------+ | Id | FirstName | Branch | +----+-----------+--------+ | 1 | John | CS | | 2 | Carol | ME | | 3 | David | ME | | 4 | Bob | CE | | 5 | Robert | EE | | 6 | Chris | EEE | | 7 | James | ME | +----+-----------+--------+ 7 rows in set (0.00 sec)
Following is the query to get records in a certain order using MySQL. The order we have set to begin with Branch ‘ME’:
mysql> select *from DemoTable order by if(Branch='ME',1,0)DESC,Branch;
This will produce the following output:
+----+-----------+--------+ | Id | FirstName | Branch | +----+-----------+--------+ | 2 | Carol | ME | | 3 | David | ME | | 7 | James | ME | | 4 | Bob | CE | | 1 | John | CS | | 5 | Robert | EE | | 6 | Chris | EEE | +----+-----------+--------+ 7 rows in set (0.00 sec)
