MySQL Select when a grouped record has multiple matching strings?
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)
