MySQL query to select rows older than a week?

For this, you can use DATEDIFF() function. The current date time is as follows −

mysql> select now(); +---------------------+ | now() | +---------------------+ | 2019-06-09 19:15:56 | +---------------------+ 1 row in set (0.00 sec)

Let us first create a table −

mysql> create table DemoTable -> ( -> ShippingDate datetime -> ); Query OK, 0 rows affected (0.66 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('2019-06-01'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable values('2019-06-02'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable values('2019-06-14'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable values('2019-05-21'); Query OK, 1 row affected (0.24 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

Output

+---------------------+ | ShippingDate | +---------------------+ | 2019-06-01 00:00:00 | | 2019-06-02 00:00:00 | | 2019-06-14 00:00:00 | | 2019-05-21 00:00:00 | +---------------------+ 4 rows in set (0.00 sec)

Following is the query to select rows older than a week. Let’s say the current date is “2019-06-09”. Therefore, the rows would get selected older than a week i.e. before “2019-06-02” −

mysql> select *from DemoTable where DATEDIFF(now(),ShippingDate) > 7;

Output

+---------------------+ | ShippingDate       | +---------------------+ | 2019-06-01 00:00:00 | | 2019-05-21 00:00:00 | +---------------------+ 2 rows in set (0.00 sec)
