Implement MySQL REGEXP to fetch records with . and numbers

MySQLMySQLi Database

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Version varchar(20)
   -> );
Query OK, 0 rows affected (0.77 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('1.0.0');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable values('2.s6.9');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values('1.5.0');
Query OK, 1 row affected (0.12 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+---------+
| Version |
+---------+
| 1.0.0   |
| 2.s6.9  |
| 1.5.0   |
+---------+
3 rows in set (0.00 sec)

Here is the query to implement MySQL REGEXP to fetch records with . and numbers −

mysql> select *from DemoTable
   -> where Version regexp '^[0-9]+\.[0-9]+(\.[0-9]+)*';

This will produce the following output −

+---------+
| Version |
+---------+
| 1.0.0   |
| 1.5.0   |
+---------+
2 rows in set (0.00 sec)
