MySQL select only a single value from 5 similar values?

Let us first create a table −

mysql> create table DemoTable800 (
   Value int
);
Query OK, 0 rows affected (0.59 sec)

Insert some records in the table using insert command. Here, we have inserted 5 similar values −

mysql> insert into DemoTable800 values(10);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable800 values(10);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable800 values(10);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable800 values(10);
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable800 values(10);
Query OK, 1 row affected (0.10 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable800;

This will produce the following output -

+-------+
| Value |
+-------+
| 10    |
| 10    |
| 10    |
| 10    |
| 10    |
+-------+
5 rows in set (0.00 sec)

Following is the query to select only a single value from 5 similar values −

mysql> select distinct Value from DemoTable800

This will produce the following output -

+-------+
| Value |
+-------+
| 10    |
+-------+
1 row in set (0.00 sec)
