MySQL NOW() Function
 MySQL Date Functions
Definition and Usage
NOW() returns the current date and time.
Syntax
Example
The following SELECT statement:
| SELECT NOW(),CURDATE(),CURTIME() |
will result in something like this:
| NOW() |
CURDATE() |
CURTIME() |
| 2008-11-11 12:45:34 |
2008-11-11 |
12:45:34 |
Example
The following SQL creates an "Orders" table with a datetime column (OrderDate):
CREATE TABLE Orders
(
OrderId int NOT NULL,
ProductName varchar(50) NOT NULL,
OrderDate datetime NOT NULL DEFAULT NOW(),
PRIMARY KEY (OrderId)
) |
Notice that the OrderDate column specifies NOW() as the default value. As
a result, when you insert a row into the table, the current date and time are
automatically inserted into the column.
Now we want to insert a record into the "Orders" table:
| INSERT INTO Orders (ProductName) VALUES ('Jarlsberg Cheese') |
The "Orders" table will now look something like this:
| OrderId |
ProductName |
OrderDate |
| 1 |
Jarlsberg Cheese |
2008-11-11 13:23:44.657 |
