The NOW() function gives current datetime as a timestamp while CURDATE() gives only current date, not time.
Now let us work on both the functions with the help of select statement. The query is as follows −
The following is a demo of NOW() function −
mysql> select NOW();
The following is the output −
+---------------------+ | now() | +---------------------+ | 2018-11-27 15:17:01 | +---------------------+ 1 row in set (0.00 sec)
A demo of CURDATE().
mysql> select CURDATE();
The following is the output that displays only date, not time −
+------------+ | curdate() | +------------+ | 2018-11-27 | +------------+ 1 row in set (0.00 sec)
Now let us understand this with the help of table. Let us create a table −
mysql> create table CurrentdateAndNowDemo −> ( −> Time datetime −> ); Query OK, 0 rows affected (0.82 sec)
Inserting records into table with the help of now() and curdate(). The query is as follows −
mysql> insert into CurrentdateAndNowDemo values(now()); Query OK, 1 row affected (0.11 sec) mysql> insert into CurrentdateAndNowDemo values(curdate()); Query OK, 1 row affected (0.14 sec)
Now let us check the now() function gives current datetime or not and curdate() gives current date or not. The query is as follows −
mysql> select *from CurrentdateAndNowDemo;
The following is the output that displays the current datetime and current date using now() and curdate() respectively −
+---------------------+ | Time | +---------------------+ | 2018-11-27 15:16:32 | | 2018-11-27 00:00:00 | +---------------------+ 2 rows in set (0.00 sec)
