To store BloodType, use varchar(3) or ENUM. Let us first create a table −
mysql> create table DemoTable1855 ( BloodType varchar(3) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1855 values('A+'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1855 values('A-'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1855 values('B+'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1855 values('B-'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1855 values('AB+'); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1855;
This will produce the following output −
+-----------+ | BloodType | +-----------+ | A+ | | A- | | B+ | | B- | | AB+ | +-----------+ 5 rows in set (0.00 sec)
