MySQL query to get the count of rows in which two or more specified values appear?

To get the count of rows in which two or more specified values appear, let us first create a sample table:

mysql> create table specifiedValuesDemo
   -> (
   -> Value int,
   -> Value2 int,
   -> Value3 int
   -> );
Query OK, 0 rows affected (0.60 sec)

Following is the query to insert some records in the table using insert command:

mysql> insert into specifiedValuesDemo values(10,15,20);
Query OK, 1 row affected (0.17 sec)

mysql> insert into specifiedValuesDemo values(40,10,20);
Query OK, 1 row affected (0.16 sec)

mysql> insert into specifiedValuesDemo values(80,20,1000);
Query OK, 1 row affected (0.12 sec)

Following is the query to display records from the table using select command:

mysql> select *from specifiedValuesDemo;

This will produce the following output

+-------+--------+--------+
| Value | Value2 | Value3 |
+-------+--------+--------+
|    10 |     15 |     20 |
|    40 |     10 |     20 |
|    80 |     20 |   1000 |
+-------+--------+--------+
3 rows in set (0.00 sec)

Let us get the count of rows in which two or more specified values appear:

mysql> select count(*) from specifiedValuesDemo
   -> where 10 in(Value,Value2,Value3) and 20 in(Value,Value2,Value3);

This will produce the following output

+----------+
| count(*) |
+----------+
|        2 |
+----------+
1 row in set (0.00 sec)
