mysql> insert into DemoTable1398 values(78); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1398 values(82); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable1398 values(90); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1398 values(98); Query OK, 1 row affected (0.12 sec)
Display all records from the table using select −
