如何在 MySQL 中查詢本週的資料?


若要在 MySQL 中查詢本週的資料,可以使用 YEARWEEK() 函式。

語法如下所示

SELECT *FROM yourTableName WHERE YEARWEEK(yourDateColumnName) = YEARWEEK(NOW());

為了理解上述語法,我們建立一個表。建立表的查詢如下所示

mysql> create table currentWeekDemo
   -> (
   -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> UserName varchar(20),
   -> UserPostDate date
   -> );
Query OK, 0 rows affected (0.68 sec)

使用插入命令在表中插入一些記錄。查詢如下所示 −

mysql> insert into currentWeekDemo(UserName,UserPostDate) values('Carol','2010-01-06');
Query OK, 1 row affected (0.20 sec)
mysql> insert into currentWeekDemo(UserName,UserPostDate) values('Bob','2019-06-04');
Query OK, 1 row affected (0.17 sec)
mysql> insert into currentWeekDemo(UserName,UserPostDate) values('David','2019-03-06');
Query OK, 1 row affected (0.16 sec)
mysql> insert into currentWeekDemo(UserName,UserPostDate) values('Maxwell','2018-04-21');
Query OK, 1 row affected (0.15 sec)

使用 select 語句顯示錶中的所有記錄。查詢如下所示 −

mysql> select *from currentWeekDemo;

以下是輸出

+--------+----------+--------------+
| UserId | UserName | UserPostDate |
+--------+----------+--------------+
|      1 | Carol    | 2010-01-06   |
|      2 | Bob      | 2019-06-04   |
|      3 | David    | 2019-03-06   |
|      4 | Maxwell  | 2018-04-21   |
+--------+----------+--------------+
4 rows in set (0.00 sec)

以下是如何在 MySQL 中查詢本週的資料

mysql> select *from currentWeekDemo WHERE YEARWEEK(UserPostDate) = YEARWEEK(NOW());

以下是輸出

+--------+----------+--------------+
| UserId | UserName | UserPostDate |
+--------+----------+--------------+
|      3 | David    | 2019-03-06   |
+--------+----------+--------------+
1 row in set (0.05 sec)
