How to sort more than one column at a time in MySQL?
To sort more than one column at a time, you can use ORDER BY clause. Following is the syntax −
select yourColumnName1,yourColumnName2,yourColumnName3 from yourTableName order by yourColumnName2,yourColumnName3;
Let us first create a table −
mysql> create table doubleSortDemo -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(100), -> StudentCountryName varchar(10) -> ); Query OK, 0 rows affected (0.71 sec)
Following is the query to insert records in the table using insert command −
mysql> insert into doubleSortDemo(StudentName,StudentCountryName)
values('John','AUS');
Query OK, 1 row affected (0.21 sec)
mysql> insert into doubleSortDemo(StudentName,StudentCountryName) values('Sam','UK');
Query OK, 1 row affected (0.20 sec)
mysql> insert into doubleSortDemo(StudentName,StudentCountryName) values('Bob','US');
Query OK, 1 row affected (0.16 sec)
mysql> insert into doubleSortDemo(StudentName,StudentCountryName) values('Carol','UK');
Query OK, 1 row affected (0.32 sec)
mysql> insert into doubleSortDemo(StudentName,StudentCountryName)
values('David','AUS');
Query OK, 1 row affected (0.19 sec)
mysql> insert into doubleSortDemo(StudentName,StudentCountryName) values('Larry','UK');
Query OK, 1 row affected (0.15 sec)Following is the query to display all records from the table using select statement −
mysql> select * from doubleSortDemo;
This will produce the following output −
+-----------+-------------+--------------------+ | StudentId | StudentName | StudentCountryName | +-----------+-------------+--------------------+ | 1 | John | AUS | | 2 | Sam | UK | | 3 | Bob | US | | 4 | Carol | UK | | 5 | David | AUS | | 6 | Larry | UK | +-----------+-------------+--------------------+ 6 rows in set (0.00 sec)
Following is the query to perform MySQL sort on more than one column i.e. Student country and name −
mysql> select StudentId,StudentName,StudentCountryName from doubleSortDemo -> order by StudentCountryName,StudentName;
This will produce the following output −
+-----------+-------------+--------------------+ | StudentId | StudentName | StudentCountryName | +-----------+-------------+--------------------+ | 5 | David | AUS | | 1 | John | AUS | | 4 | Carol | UK | | 6 | Larry | UK | | 2 | Sam | UK | | 3 | Bob | US | +-----------+-------------+--------------------+ 6 rows in set (0.00 sec)
