Let’s say the current date is 2019-09-06. For our example, we will first create a table −
mysql> create table DemoTable ( AdmissionDate date ); Query OK, 0 rows affected (0.54 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('2019-01-08'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values('2018-09-06'); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable values('2016-10-26'); Query OK, 1 row affected (0.17 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+---------------+ | AdmissionDate | +---------------+ | 2019-01-08 | | 2018-09-06 | | 2016-10-26 | +---------------+ 3 rows in set (0.00 sec)
Following is the query to get the difference between date records and current date;
mysql> select datediff(now(),AdmissionDate) from DemoTable;
This will produce the following output −
+-------------------------------+ | datediff(now(),AdmissionDate) | +-------------------------------+ | 241 | | 365 | | 1045 | +-------------------------------+ 3 rows in set (0.00 sec)
