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)
