MySQL query to select records approaching in next 12 hours?
For this, you can use INTERVAL 12 hour using DATE_ADD(). Let us first create a table −
mysql> create table DemoTable (DueDateTime datetime); Query OK, 0 rows affected (0.60 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('2019-07-12 10:50:30');
Query OK, 1 row affected (0.29 sec)
mysql> insert into DemoTable values('2019-07-12 22:02:00');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable values('2019-07-12 11:12:10');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('2019-07-12 09:02:00');
Query OK, 1 row affected (0.10 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+---------------------+ | DueDateTime | +---------------------+ | 2019-07-12 10:50:30 | | 2019-07-12 22:02:00 | | 2019-07-12 11:12:10 | | 2019-07-12 09:02:00 | +---------------------+ 4 rows in set (0.00 sec)
Following is the query to select records approaching in next 12 hours −
mysql> select *from DemoTable where date_add(DueDateTime,interval 12 hour) BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 12 HOUR);
This will produce the following output −
+---------------------+ | DueDateTime | +---------------------+ | 2019-07-12 10:50:30 | | 2019-07-12 22:02:00 | | 2019-07-12 11:12:10 | +---------------------+ 3 rows in set (0.00 sec)
