Select query with regular expression in MySQL
Let us first create a table −
mysql> create table DemoTable1573
-> (
-> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
-> StudentCode varchar(20)
-> );
Query OK, 0 rows affected (0.63 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1573(StudentCode) values('STU_774');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1573(StudentCode) values('909_Sam');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1573(StudentCode) values('3_Carol_455');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable1573(StudentCode) values('David_903');
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1573;
This will produce the following output −
+-----------+-------------+
| StudentId | StudentCode |
+-----------+-------------+
| 1 | STU_774 |
| 2 | 909_Sam |
| 3 | 3_Carol_455 |
| 4 | David_903 |
+-----------+-------------+
4 rows in set (0.00 sec)
Here is the query to implement select query with regular expression −
mysql> select * from DemoTable1573 where StudentCode regexp '\land[0-9]';
This will produce the following output −
+-----------+-------------+
| StudentId | StudentCode |
+-----------+-------------+
| 2 | 909_Sam |
| 3 | 3_Carol_455 |
+-----------+-------------+
2 rows in set (0.14 sec)
