Return a specific MySQL string using regular expressions

Let us first create a table −

mysql> create table DemoTable649 (Value text);
Query OK, 0 rows affected (0.68 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable649 values('1903');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable649 values('9321010');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable649 values('983032023393');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable649 values('1234567892');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable649 values('989898989');
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable649;

This will produce the following output −

+--------------+
| Value        |
+--------------+
| 1903         |
| 9321010      |
| 983032023393 |
| 1234567892   |
| 989898989    |  
+--------------+
5 rows in set (0.00 sec)

Following is the query to return a specific MySQL string using regex −

mysql> select *from DemoTable649 where Value REGEXP '[0-9]{11}';

This will produce the following output −

+--------------+
| Value        |
+--------------+
| 983032023393 |
+--------------+
1 row in set (0.00 sec)
