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)
