MySQL query to select a record with two exact values?

For this, you can use GROUP BY HAVING clause. Let us first create a table −

mysql> create table DemoTable
(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   Value int
);
Query OK, 0 rows affected (0.52 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(Value) values(600);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable(Value) values(600);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable(Value) values(800);
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(Value) values(800);
Query OK, 1 row affected (0.09 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----+-------+
| Id | Value |
+----+-------+
|  1 |   600 |
|  2 |   600 |
|  3 |   800 |
|  4 |   800 |
+----+-------+
4 rows in set (0.00 sec)

Here is the query to select a record with two exact values −

mysql> select Value from DemoTable tbl
   where Id IN(1,2) group by Value
  having count(distinct Id)=2;

This will produce the following output −

+-------+
| Value |
+-------+
|   600 |
+-------+
1 row in set (0.07 sec)
