ORDER BY alphabet first then follow by number in MySQL?
You need to use regular expression with ORDER BY clause. The syntax is as follows:
SELECT *FROM yourTableName ORDER BY IF(yourColumnName RLIKE '^[a-z]', 1, 2),yourColumnName;
To understand the above syntax, let us create a table. The query to create a table is as follows:
mysql> create table AlphabetFirstThenNumberDemo -> ( -> Id int NOT NULL AUTO_INCREMENT, -> Name varchar(20), -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.95 sec)
Insert some records in the table using insert command. The query is as follows:
mysql> insert into AlphabetFirstThenNumberDemo(Name) values('John'); Query OK, 1 row affected (0.37 sec) mysql> insert into AlphabetFirstThenNumberDemo(Name) values('Bob'); Query OK, 1 row affected (0.21 sec) mysql> insert into AlphabetFirstThenNumberDemo(Name) values('1Sam'); Query OK, 1 row affected (0.17 sec) mysql> insert into AlphabetFirstThenNumberDemo(Name) values('Carol'); Query OK, 1 row affected (0.22 sec) mysql> insert into AlphabetFirstThenNumberDemo(Name) values('2Larry'); Query OK, 1 row affected (0.31 sec) mysql> insert into AlphabetFirstThenNumberDemo(Name) values('David'); Query OK, 1 row affected (0.27 sec) mysql> insert into AlphabetFirstThenNumberDemo(Name) values('3Mike'); Query OK, 1 row affected (0.14 sec) mysql> insert into AlphabetFirstThenNumberDemo(Name) values('Robert'); Query OK, 1 row affected (0.10 sec)
Now you can display all records from the table using select statement. The query is as follows:
mysql> select *from AlphabetFirstThenNumberDemo;
The following is the output:
+----+--------+ | Id | Name | +----+--------+ | 1 | John | | 2 | Bob | | 3 | 1Sam | | 4 | Carol | | 5 | 2Larry | | 6 | David | | 7 | 3Mike | | 8 | Robert | +----+--------+ 8 rows in set (0.00 sec)
Here is the query order by alphabet first then followed by a number. The query is as follows:
mysql> select *from AlphabetFirstThenNumberDemo -> ORDER BY IF(Name RLIKE '^[a-z]', 1, 2),Name;
The following is the output:
+----+--------+ | Id | Name | +----+--------+ | 2 | Bob | | 4 | Carol | | 6 | David | | 1 | John | | 8 | Robert | | 3 | 1Sam | | 5 | 2Larry | | 7 | 3Mike | +----+--------+ 8 rows in set (0.00 sec)
