MySQL regexp to display only records with strings or strings mixed with numbers. Ignore only the number records

For this, you can use REGEXP. Following is the syntax −

select yourColumnName from yourTableName where yourColumnName REGEXP '[a−zA&minu;Z]';

Let us create a table −

mysql> create table demo41
−> (
−> name varchar(40)
−> );
Query OK, 0 rows affected (0.64 sec)

Insert some records into the table with the help of insert command −

mysql> insert into demo41 values('John Smith34')
−> ;
Query OK, 1 row affected (0.13 sec)
mysql> insert into demo41 values('John Smith');
Query OK, 1 row affected (0.11 sec)
mysql> insert into demo41 values('9234John Smith');
Query OK, 1 row affected (0.14 sec)
mysql> insert into demo41 values('john smith');
Query OK, 1 row affected (0.23 sec)
mysql> insert into demo41 values('98775');
Query OK, 1 row affected (0.15 sec)

Display records from the table using select statement −

mysql> select *from demo41;

This will produce the following output −

+----------------+
| name           |
+----------------+
| John Smith34   |
| John Smith     |
| 9234John Smith |
| john smith     |
| 98775          |
+----------------+
5 rows in set (0.00 sec)

Following is the query for MySQL regexp −

mysql> select name from demo41 where name REGEXP '[a−zA−Z]';

This will produce the following output −

+----------------+
| name           |
+----------------+
| John Smith34   |
| John Smith     |
| 9234John Smith |
| john smith     |
+----------------+
4 rows in set (0.00 sec)
