MySQL query to select date >= current date - 3 weeks?
Use the concept of DATE_SUB(). Let us first create a table −
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, ArrivalDate datetime ); Query OK, 0 rows affected (1.02 sec)
Note: Let’s say the current date is 2019-06-08
Insert some records in the table using insert command −
mysql> insert into DemoTable(ArrivalDate) values('2019-05-15');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(ArrivalDate) values('2019-06-08');
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable(ArrivalDate) values('2019-05-20');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable(ArrivalDate) values('2019-05-12');
Query OK, 1 row affected (0.12 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+----+---------------------+ | Id | ArrivalDate | +----+---------------------+ | 1 | 2019-05-15 00:00:00 | | 2 | 2019-06-08 00:00:00 | | 3 | 2019-05-20 00:00:00 | | 4 | 2019-05-12 00:00:00 | +----+---------------------+ 4 rows in set (0.00 sec)
Here is the query to select the dates, which are greater than equal to current date - 3 weeks −
mysql> select ArrivalDate from DemoTable where ArrivalDate> DATE_SUB(curdate(),INTERVAL 3 WEEK);
Output
+---------------------+ | ArrivalDate | +---------------------+ | 2019-06-08 00:00:00 | | 2019-05-20 00:00:00 | +---------------------+ 2 rows in set (0.00 sec)
