MySQL Select when a grouped record has multiple matching strings?

MySQLMySQLi Database

You can use regular expression for this. Let us first create a table −

mysql> create table DemoTable
   (
   ProductId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   ProductName varchar(20)
   );
Query OK, 0 rows affected (0.19 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(ProductName) values('Product-1');
Query OK, 1 row affected (0.05 sec)

mysql> insert into DemoTable(ProductName) values('Product2');
Query OK, 1 row affected (0.06 sec)

mysql> insert into DemoTable(ProductName) values('Product1');
Query OK, 1 row affected (0.04 sec)

mysql> insert into DemoTable(ProductName) values('Product-3');
Query OK, 1 row affected (0.05 sec)

mysql> insert into DemoTable(ProductName) values('Product3');
Query OK, 1 row affected (0.05 sec)

mysql> insert into DemoTable(ProductName) values('Product-4');
Query OK, 1 row affected (0.09 sec)

mysql> insert into DemoTable(ProductName) values('Product4');
Query OK, 1 row affected (0.05 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-----------+-------------+
| ProductId | ProductName |
+-----------+-------------+
| 1         | Product-1   |
| 2         | Product2    |
| 3         | Product1    |
| 4         | Product-3   |
| 5         | Product3    |
| 6         | Product-4   |
| 7         | Product4    |
+-----------+-------------+
7 rows in set (0.00 sec)

Following is the query for a grouped record having multiple matching strings −

mysql> select *from DemoTable
where ProductName regexp 'Product[1234].*';

This will produce the following output −

+-----------+-------------+
| ProductId | ProductName |
+-----------+-------------+
| 2         | Product2    |
| 3         | Product1    |
| 5         | Product3    |
| 7         | Product4    |
+-----------+-------------+
4 rows in set (0.00 sec)
