Find the difference between dates in the form of months with MySQL

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Date1 date,
   -> Date2 date
   -> );
Query OK, 0 rows affected (1.04 sec)

Insert some records in the table using insert command &miuns;

mysql> insert into DemoTable values('2017-01-10','2017-12-10');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('2018-12-31','2015-01-02');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('2020-03-01','2019-06-15');
Query OK, 1 row affected (0.19 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+------------+------------+
| Date1      | Date2      |
+------------+------------+
| 2017-01-10 | 2017-12-10 |
| 2018-12-31 | 2015-01-02 |
| 2020-03-01 | 2019-06-15 |
+------------+------------+
3 rows in set (0.00 sec)

Here is the query to find the difference between dates in the form of months −

mysql> select abs(timestampdiff(MONTH,Date1,Date2)) from DemoTable;

This will produce the following output −

+---------------------------------------+
| abs(timestampdiff(MONTH,Date1,Date2)) |
+---------------------------------------+
|                                    11 |
|                                    47 |
|                                     8 |
+---------------------------------------+
