How can I create a MySQL table with a column with only 3 possible given values?

For this, use the ENUM data type. Let us first create a table −

mysql> create table DemoTable838(Color ENUM('RED','GREEN','BLUE'));
Query OK, 0 rows affected (0.67 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable838 values('RED');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable838 values('Green');
Query OK, 1 row affected (0.64 sec)
mysql> insert into DemoTable838 values('Blue');
Query OK, 1 row affected (0.88 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable838;

This will produce the following output −

+-------+
| Color |
+-------+
| RED   |
| GREEN |
| BLUE  |
+-------+
3 rows in set (0.00 sec)
