MySQL query to return all records with a datetime older than 1 week
To get dates older than 1 week, you can use the following syntax −
select *from yourTableName where yourColumnName < now() - interval 1 week;
To understand the above concept, let us create a table. The query to create a table is as follows −
mysql> create table DatesOfOneWeek −> ( −> ArrivalTime datetime −> ); Query OK, 0 rows affected (0.87 sec)
Insert some records in the table −
mysql> insert into DatesOfOneWeek values(date_add(now(),interval 2 week));
Query OK, 1 row affected (0.11 sec)
mysql> insert into DatesOfOneWeek values('2018-11-04');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DatesOfOneWeek values('2018-11-25');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DatesOfOneWeek values(date_add(now(),interval -1 week));
Query OK, 1 row affected (0.14 sec)
mysql> insert into DatesOfOneWeek values(date_add(now(),interval 1 week));
Query OK, 1 row affected (0.11 sec)Let us check the records which we have inserted above are present or not. The query to display all records from the table is as follows −
mysql> select *from DatesOfOneWeek;
The following is the output −
+---------------------+ | ArrivalTime | +---------------------+ | 2018-12-20 18:11:02 | | 2018-11-04 00:00:00 | | 2018-11-25 00:00:00 | | 2018-11-29 18:11:40 | | 2018-12-13 18:11:46 | +---------------------+ 5 rows in set (0.00 sec)
Here is the MySQL query to get a date which was in the past i.e. all the date before 1 week −
mysql> select *from DatesOfOneWeek where ArrivalTime < now() - interval 1 week;
The following is the output −
+---------------------+ | ArrivalTime | +---------------------+ | 2018-11-04 00:00:00 | | 2018-11-25 00:00:00 | | 2018-11-29 18:11:40 | +---------------------+ 3 rows in set (0.00 sec)
