如何查询本周的MySQL？
要查询本周的MySQL，可以使用YEARWEEK()函数。
语法如下
SELECT *FROM yourTableName WHERE YEARWEEK(yourDateColumnName) = YEARWEEK(NOW());
为了理解上述语法，让我们创建一个表。创建表的查询如下
mysql> create table currentWeekDemo -> ( -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> UserName varchar(20), -> UserPostDate date -> );
使用insert命令在表中插入一些记录。查询如下-
mysql> insert into currentWeekDemo(UserName,UserPostDate) values('Carol','2010-01-06');
mysql> insert into currentWeekDemo(UserName,UserPostDate) values('Bob','2019-06-04');
mysql> insert into currentWeekDemo(UserName,UserPostDate) values('David','2019-03-06');
mysql> insert into currentWeekDemo(UserName,UserPostDate) values('Maxwell','2018-04-21');使用select语句显示表中的所有记录。查询如下-
mysql> select *from currentWeekDemo;
以下是输出
+--------+----------+--------------+ | 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)
以下是如何在本周查询MySQL
mysql> select *from currentWeekDemo WHERE YEARWEEK(UserPostDate) = YEARWEEK(NOW());
以下是输出
+--------+----------+--------------+ | UserId | UserName | UserPostDate | +--------+----------+--------------+ | 3 | David | 2019-03-06 | +--------+----------+--------------+ 1 row in set (0.05 sec)
