How to arrange data in s specific order in MySQL?
Use ORDER BY IF() to arrange data in a specific order. Following is the syntax −
select *from yourTableName ORDER BY IF(yourColumnName=yourValue1 OR yourColumnName=yourValue2 OR yourColumnName=yourValue3,yourColumnName, ~yourColumnName) ASC;
Let us first create a table −
mysql> create table arrangeDataInSpecificOrder -> ( -> StudentId int, -> StudentName varchar(20) -> ); Query OK, 0 rows affected (0.64 sec)
Following is the query to insert some records in the table using insert command −
mysql> insert into arrangeDataInSpecificOrder values(10,'Larry'); Query OK, 1 row affected (0.12 sec) mysql> insert into arrangeDataInSpecificOrder values(15,'Mike'); Query OK, 1 row affected (0.09 sec) mysql> insert into arrangeDataInSpecificOrder values(100,'Sam'); Query OK, 1 row affected (0.16 sec) mysql> insert into arrangeDataInSpecificOrder values(70,'Carol'); Query OK, 1 row affected (0.12 sec) mysql> insert into arrangeDataInSpecificOrder values(90,'Bob'); Query OK, 1 row affected (0.14 sec) mysql> insert into arrangeDataInSpecificOrder values(300,'David'); Query OK, 1 row affected (0.12 sec)
Following is the query to display all records from the table using select statement −
mysql> select * from arrangeDataInSpecificOrder;
This will produce the following output −
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 10 | Larry | | 15 | Mike | | 100 | Sam | | 70 | Carol | | 90 | Bob | | 300 | David | +-----------+-------------+ 6 rows in set (0.00 sec)
Here is the query to arrange data in specific order −
mysql> select * from arrangeDataInSpecificOrder ORDER BY IF(StudentId=300 OR StudentId=100 OR StudentId=10,StudentId, ~StudentId) ASC;
This will produce the following output −
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 10 | Larry | | 100 | Sam | | 300 | David | | 90 | Bob | | 70 | Carol | | 15 | Mike | +-----------+-------------+ 6 rows in set (0.00 sec)
