UNIX_TIMESTAMP with date in MySQL query to fetch records after a specific date in different format?

For this, you can use STR_TO_DATE(), since we have date records in the following format: 21/11/2019.

Let us first create a table −

mysql> create table DemoTable1808      (      AdmissionDate varchar(20)      ); Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1808 values('21/11/2019'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1808 values('01/01/2018'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1808 values('26/09/2017'); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1808;

This will produce the following output −

+---------------+ | AdmissionDate | +---------------+ | 21/11/2019    | | 01/01/2018    | | 26/09/2017    | +---------------+ 3 rows in set (0.00 sec)

Here is the query to fetch records after a particular date −

mysql> select * from DemoTable1808    where str_to_date(AdmissionDate,'%d/%m/%Y') > '2018-12-31';

This will produce the following output −

+---------------+ | AdmissionDate | +---------------+ | 21/11/2019    | +---------------+ 1 row in set (0.00 sec)
