最佳的 MySQL 存储每周事件的方法？

让我们看看在 MySQL 中存储每周事件的最佳方法。首先创建一个新表格并包括每天的字段。

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)

使用 insert 命令向表格中插入一些记录。查询如下所示−

mysql> insert into WeeklyEventDemo(EventName,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday,StartDate,EndDate) values('Event-1',0,0,0,0,1,0,0,'2018-03-21','2019-03-08');
Query OK, 1 row affected (0.14 sec)
mysql> insert into WeeklyEventDemo(EventName,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday,StartDate,EndDate) values('Event-2',0,0,0,0,0,1,0,'2018-03-21','2019-03-08');
Query OK, 1 row affected (0.16 sec)

使用 select 语句显示表格中的所有记录。查询如下所示−

mysql> select * from WeeklyEventDemo;

以下是输出结果

+----+-----------+--------+---------+-----------+----------+--------+----------+--------+------------+------------+
| ID | EventName | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday | Sunday | StartDate | EndDate |
+----+-----------+--------+---------+-----------+----------+--------+----------+--------+------------+------------+
| 1 | Event-1 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 2018-03-21 | 2019-03-08 |
| 2 | Event-2 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 2018-03-21 | 2019-03-08 |
+----+-----------+--------+---------+-----------+----------+--------+----------+--------+------------+------------+
2 rows in set (0.00 sec)

以下是获取 MySQL 中每周事件的查询

mysql> select * from WeeklyEventDemo where Friday=1;

以下是输出结果

+----+-----------+--------+---------+-----------+----------+--------+----------+--------+------------+------------+
| ID | EventName | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday | Sunday | StartDate | EndDate |
+----+-----------+--------+---------+-----------+----------+--------+----------+--------+------------+------------+
| 1 | Event-1 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 2018-03-21 | 2019-03-08 |
+----+-----------+--------+---------+-----------+----------+--------+----------+--------+------------+------------+
1 row in set (0.00 sec)
