Check if a string contains numbers in MySQL?
To check a string contains numbers, you can use regexp i.e. Regular Expressions. The syntax is as follows −
SELECT *FROM yourTableName where yourColumnName REGEXP ‘[0-9]’;
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table StringContainsNumber -> ( -> Id int not null auto_increment, -> Words text, -> primary key(Id) -> ); Query OK, 0 rows affected (0.53 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into StringContainsNumber(Words) values('He12345llo');
Query OK, 1 row affected (0.19 sec)
mysql> insert into StringContainsNumber(Words) values('MySQL is not a programming
4language');
Query OK, 1 row affected (0.17 sec)
mysql> insert into StringContainsNumber(Words) values('Java is an object oriented');
Query OK, 1 row affected (0.18 sec)
mysql> insert into StringContainsNumber(Words) values('Java does not support 456 multiple
inheritance');
Query OK, 1 row affected (0.20 sec)
mysql> insert into StringContainsNumber(Words) values('MySQL is a RDBMS 456');
Query OK, 1 row affected (0.19 sec)Display all records from the table using select statement. The query is as follows −
mysql> select *from StringContainsNumber;
The following is the output.
+----+------------------------------------------------+ | Id | Words | +----+------------------------------------------------+ | 1 | He12345llo | | 2 | MySQL is not a programming 4language | | 3 | Java is an object oriented | | 4 | Java does not support 456 multiple inheritance | | 5 | MySQL is a RDBMS 456 | +----+------------------------------------------------+ 5 rows in set (0.00 sec)
Here is the query to find the string that has numbers using REGEXP −
mysql> select *from StringContainsNumber where Words regexp '[0-9]';
The following is the output −
+----+------------------------------------------------+ | Id | Words | +----+------------------------------------------------+ | 1 | He12345llo | | 2 | MySQL is not a programming 4language | | 4 | Java does not support 456 multiple inheritance | | 5 | MySQL is a RDBMS 456 | +----+------------------------------------------------+ 4 rows in set (0.11 sec)
