How to select row when column must satisfy multiple value in MySQL?
For this, you can use GROUP BY HAVING clause along with IN(). Let us first create a table −
mysql> create table DemoTable1885 ( FirstName varchar(20), Subject varchar(50) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1885 values('John','MySQL'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1885 values('John','MongoDB'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1885 values('Carol','MySQL'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1885 values('David','Java'); Query OK, 1 row affected (0.00 sec)
Display some records in the table using insert command −
mysql> select * from DemoTable1885;
This will produce the following output −
+-----------+---------+ | FirstName | Subject | +-----------+---------+ | John | MySQL| | John | MongoDB| | Carol | MySQL| | David | Java | +-----------+---------+ 4 rows in set (0.00 sec)
Here is the query to select row when column must satisfy multiple value:
mysql> select FirstName from DemoTable1885 where Subject IN('MySQL','MongoDB') group by FirstName having count(*)=2;
This will produce the following output −
+-----------+ | FirstName | +-----------+ | John | +-----------+ 1 row in set (0.00 sec)
