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)
