Select a Row by Subtracting Dates in MySQL

For this, use TIMESTAMPDIFF(). Let us create a table −

mysql> create table demo42
−> (
−> start_date datetime
−> );
Query OK, 0 rows affected (0.77 sec)

Insert some records into the table with the help of insert command −

mysql> insert into demo42 values('2020-01-10 12:30:05');
Query OK, 1 row affected (0.11 sec)

mysql> insert into demo42 values('2019-02-24 10:40:45');
Query OK, 1 row affected (0.11 sec)

mysql> insert into demo42 values('2020-05-12 05:45:55');
Query OK, 1 row affected (0.17 sec)

mysql> insert into demo42 values('2020-05-12 05:40:55');
Query OK, 1 row affected (0.15 sec)

mysql> insert into demo42 values('2020-05-12 05:42:55');
Query OK, 1 row affected (0.11 sec)

Display records from the table using select statement −

mysql> select *from demo42;

This will produce the following output −

+---------------------+
| start_date          |
+---------------------+
| 2020-01-10 12:30:05 |
| 2019-02-24 10:40:45 |
| 2020-05-12 05:45:55 |
| 2020-05-12 05:40:55 |
| 2020-05-12 05:42:55 |
+---------------------+
5 rows in set (0.00 sec)

Following is the query to select a row with TIMESTAMPDIFF −

mysql> select *from demo42
−> where ABS(TIMESTAMPDIFF(MINUTE,start_date, '2020−05−12 05:40:55')) < 5;

This will produce the following output −

+---------------------+
| start_date          |
+---------------------+
| 2020−05−12 05:40:55 |
| 2020−05−12 05:42:55 |
+---------------------+
2 rows in set (0.00 sec)
