At first, find the current date and get the difference between joining date and current date using the DATEDIFF().
The current date is as follows −
mysql> select curdate(); +------------+ | curdate() | +------------+ | 2019-10-26 | +------------+ 1 row in set (0.00 sec)
Let us first create a table −
mysql> create table DemoTable -> ( -> JoiningDate varchar(40) -> ); Query OK, 0 rows affected (0.61 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('10/10/1998'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values('31/12/2010'); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable values('01/01/2017'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values('25/10/2019'); Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output−
+-------------+ | JoiningDate | +-------------+ | 10/10/1998 | | 31/12/2010 | | 01/01/2017 | | 25/10/2019 | +-------------+ 4 rows in set (0.00 sec)
Here is the query to return the difference between current and joining date −
mysql> select datediff(curdate(),str_to_date(JoiningDate,'%d/%m/%Y')) from DemoTable;
This will produce the following output −
+---------------------------------------------------------+ | datediff(curdate(),str_to_date(JoiningDate,'%d/%m/%Y')) | +---------------------------------------------------------+ | 7686 | | 3221 | | 1028 | | 1 | +---------------------------------------------------------+ 4 rows in set (0.00 sec)
