MySQL - Convert YYYY-MM-DD to UNIX timestamp

MySQLMySQLi Database

To convert date to UNIX timestamp, use UNIX_TIMESTAMP() in MySQL −

mysql> create table DemoTable1997
(
   DueDate date
);
Query OK, 0 rows affected (0.58 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1997 values('2018-10-11');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1997 values('2019-12-21');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1997 values('2017-01-31');
Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1997;

This will produce the following output −

+------------+
| DueDate    |
+------------+
| 2018-10-11 |
| 2019-12-21 |
| 2017-01-31 |
+------------+
3 rows in set (0.00 sec)

Here is the query to convert YYYY-MM-DD to unix timestamp −

mysql> select unix_timestamp(cast(DueDate as date)) as Result from DemoTable1997;

This will produce the following output −

+------------+
| Result     |
+------------+
| 1539196200 |
| 1576866600 |
| 1485801000 |
