How to select only non - numeric values from varchar column in MySQL?

You need to use REGEXP for this. The syntax is as follows

SELECT *FROM yourTableName WHERE yourColumnName REGEXP '[a-zA-Z]';

To understand the concept, let us create a table. The query to create a table is as follows

mysql> create table SelectNonNumericValue    -> (    -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,    -> UserId varchar(100)    -> ); Query OK, 0 rows affected (0.58 sec)

Insert some records in the table using insert command. The query is as follows

mysql> insert into SelectNonNumericValue(UserId) values('123John'); Query OK, 1 row affected (0.12 sec) mysql> insert into SelectNonNumericValue(UserId) values('58475Carol98457Taylor24'); Query OK, 1 row affected (0.52 sec) mysql> insert into SelectNonNumericValue(UserId) values('199575Sam124'); Query OK, 1 row affected (0.14 sec) mysql> insert into SelectNonNumericValue(UserId) values('Mike2456'); Query OK, 1 row affected (0.14 sec) mysql> insert into SelectNonNumericValue(UserId) values('1000'); Query OK, 1 row affected (0.12 sec) mysql> insert into SelectNonNumericValue(UserId) values('1001'); Query OK, 1 row affected (0.21 sec) mysql> insert into SelectNonNumericValue(UserId) values('10293Bob'); Query OK, 1 row affected (0.13 sec) mysql> insert into SelectNonNumericValue(UserId) values('David'); Query OK, 1 row affected (0.30 sec) mysql> insert into SelectNonNumericValue(UserId) values('2456'); Query OK, 1 row affected (0.15 sec)

Display all records from the table using a select statement. The query is as follows

mysql> select *from SelectNonNumericValue;

The following is the output

+----+-------------------------+ | Id | UserId                  | +----+-------------------------+ | 1 | 123John                  | | 2 | 58475Carol98457Taylor24  | | 3 | 199575Sam124             | | 4 | Mike2456                 | | 5 | 1000                     | | 6 | 1001                     | | 7 | 10293Bob | | 8 | David | | 9 | 2456 | +----+-------------------------+ 9 rows in set (0.00 sec)

Here is the query to select non-numeric values

mysql> select *from SelectNonNumericValue WHERE UserId REGEXP '[a-zA-Z]';

The following is the output that ignores the numeric values

+----+-------------------------+ | Id | UserId | +----+-------------------------+ | 1 | 123John | | 2 | 58475Carol98457Taylor24 | | 3 | 199575Sam124 | | 4 | Mike2456 | | 7 | 10293Bob | | 8 | David | +----+-------------------------+ 6 rows in set (0.00 sec)
