The easiest way to achieve this is by using REGEXP. Let us first create a table −
mysql> create table DemoTable ( Id varchar(50) ); Query OK, 0 rows affected (0.77 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('John123'); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable values('123Chris'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values('99Bob'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values('19David'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values('99S'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable values('10M'); Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----------+ | Id | +----------+ | John123 | | 123Chris | | 99Bob | | 19David | | 99S | | 10M | +----------+ 6 rows in set (0.00 sec)
Following is the query to display records with arrangements in the form of numbers and letter −
mysql> select *from DemoTable where Id regexp '^[0-9][0-9][A-Z]$';
This will produce the following output −
+------+ | Id | +------+ | 99S | | 10M | +------+ 2 rows in set (0.00 sec)
