How to return distinct values in MySQL and their count?

To return only the distinct values, use GROUP BY clause.

Let us first create a table −

mysql> create table DemoTable754 (ProductPrice int);
Query OK, 0 rows affected (0.48 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable754 values(200);
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable754 values(500);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable754 values(200);
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable754 values(500);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable754 values(800);
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable754 values(900);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable754 values(200);
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable754 values(200);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable754 values(900);
Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable754;

This will produce the following output -

+--------------+
| ProductPrice |
+--------------+
|          200 |
|          500 |
|          200 |
|          500 |
|          800 |
|          900 |
|          200 |
|          200 |
|          900 |
+--------------+
9 rows in set (0.00 sec)

Following is the query to return distinct values and their count −

mysql> select ProductPrice,count(ProductPrice) from DemoTable754 group by ProductPrice;

This will produce the following output -

+--------------+---------------------+
| ProductPrice | count(ProductPrice) |
+--------------+---------------------+
|          200 |                   4 |
|          500 |                   2 |
|          800 |                   1 |
|          900 |                   2 |
+--------------+---------------------+
4 rows in set (0.00 sec)
