Best way to store weekly event in MySQL?
Let us see the best way to store weekly events in MySQL. For that, first create a new table and include fields for every day as well.
mysql> create table WeeklyEventDemo -> ( -> ID int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> EventName varchar(20), -> Monday tinyint(1), -> Tuesday tinyint(1), -> Wednesday tinyint(1), -> Thursday tinyint(1), -> Friday tinyint(1), -> Saturday tinyint(1), -> Sunday tinyint(1), -> StartDate date, -> EndDate date -> ); Query OK, 0 rows affected (0.55 sec)
