Set a MySQL field with the current date (UNIX_TIMESTAMP(now))
For this, use unix_timestamp(). Let us first create a table −
mysql> create table DemoTable1894
(
Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
DueTime int
);
Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1894 values();
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1894 values();
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1894 values();
Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1894;
This will produce the following output −
+----+---------+
| Id | DueTime |
+----+---------+
| 1 | NULL |
| 2 | NULL |
| 3 | NULL |
+----+---------+
3 rows in set (0.00 sec)
Here is the query to set a field with UNIX Timestamp −
mysql> update DemoTable1894 set DueTime=unix_timestamp(now());
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1894;
This will produce the following output −
+----+------------+
| Id | DueTime |
+----+------------+
| 1 | 1576042722 |
| 2 | 1576042722 |
| 3 | 1576042722 |
+----+------------+
3 rows in set (0.00 sec)
