How to batch update MySQL table?

mysql> create table DemoTable -> ( -> BreakfastTime time -> ); Query OK, 0 rows affected (0.59 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('7:30:45');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('8:00:30');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable values('7:55:00');
Query OK, 1 row affected (0.10 sec)Display all records from the table using select statement −
mysql> select * from DemoTable;
