MySQL Regular expressions: How to match digits in the string with d?
To match digits in the string, the syntax in MySQL is as follows −
select * from yourTab leName where yourColumnName regexp '[0-9]';
To understand the above syntax, let us create a table −
mysql> create table DemoTable1841 ( Code varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1841 values('John231');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1841 values('19876Sam');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1841 values('Carol');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1841 values('67474');
Query OK, 1 row affected (0.00 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1841;
This will produce the following output −
+----------+ | Code | +----------+ | John231 | | 19876Sam | | Carol | | 67474 | +----------+ 4 rows in set (0.00 sec)
Here is the regular expression to match digit in string −
mysql> select * from DemoTable1841 where Code regexp '[0-9]';
This will produce the following output −
+----------+ | Code | +----------+ | John231 | | 19876Sam | | 67474 | +----------+ 3 rows in set (0.00 sec)
